INTRODUCTION

The VX-5c projector is a professional quality DMDTMprojector that uses Digital Light
Processing

TM

(DLPTM) technology from Texas Instruments to achieve high-brightness

multimedia and video projection. Both models are compatible
with standard international video formats and can interface with
IBM

TM

-compatible PC, MacintoshTMcomputers and high-defini­tion (DTV) decoders. The VX-5c is ideal for use in large audi­ence venues in which there may be high levels of ambient light,
such as in corporate boardrooms, auditoriums, and large theaters
with large screens.

The features of the VX-5c include:

Includes the VHD Ultra Controller for optimum picture quality when
using NTSC sources

1280 x 1024 native resolution, with other resolutions fully scaleable
3000 ANSI lumens light output
Contrast ratio of greater than 250:1 ANSI, 400:1 full field
Tandem horizontal and vertical sizing software control
Independent vertical stretch for changing aspect ratios
Interchangeable lenses for diagonal screen sizes up to 40 or more feet
Memory for up to 99 custom “channels” (source setups)
Intuitive on-screen menus or hidden direct control
Input switching with keypad
Built-in RS-232 and RS-422 ports for computer control and networked projectors
Modular design for easy servicing.

How The Projector Work?

The VX-5c can accept data/graphics and video input signals for projection on to front
or rear flat screens. High brightness light is generated by an internal 700W Xenon arc
lamp, then modulated by three DMD (digital micromirror device) panels that provide
digitized red, green or blue color information. Light from the “on” pixels of each panel
is reflected, converged and then projected to the screen through a single front lens,
where all pixels are perfectly superimposed as a sharp full-color image.

This section explains how to install and set up the projector. If you are familiar with the projector and want to
quickly set it up for temporary use, follow the Quick Setup instructions below. For a more complete setup, fol­low the instructions and guides covered in the remaining subsections.

NOTE: 1) The lens is not mounted when the projector is shipped from the factory. For instructions on how to
install or replace a lens, refer to 4.5, Replacing the Lens.

2.1 Quick Setup

Follow these steps for quick setup of the projector in a standard floor mount position.

STEP 1



Position the Projector

Set the projector at the expected throw distance (projector-to-screen distance) and vertical posi­tion. See 2.3, Projector Position and Mounting and Appendix E. Make sure that the projector is
level from side-to-side (see 2.7, Leveling).

STEP 2



Connect a Source

Locate the main input panel at the rear of the projector. The lower left area, labeled INPUT 1,
accepts an RGB input via BNC connectors. The upper right area (assuming a video decoder is
installed) accepts a composite video at INPUT 3 or S-video input at INPUT 4. Connect your
source to the appropriate panel connectors.

STEP 3



Connect the Line Cord to AC Power

Connect the projector’s 13 amp high-current rated line cord to the AC receptacle at the lower
right corner of the projector and to AC. Input power required is 100 - 240 VAC, 50 to 60 Hz @

11.5 amps (@ 100 V). Use only a high-current 13 amp rated cord. See Section 5.

WARNING

Do not attempt operation if the AC supply and cord are not within the

specified voltage and power range.

STEP 4



Turn the Projector ON

Using either the built-in or remote keypad, press and hold for approximately 1 second to
turn the projector on (or press ). Let the projector warm up for about five minutes.
The POWER LED, located in the lower right corner of the rear input panel, should glow a
steady green.

STEP 5



Select a Source

Using either the built-in or remote keypad, press , , , or to select and display
the image for the source you connected in Step 2. The display will resize as needed, producing
an image as large as possible for the type of source present.

STEP 6 Adjust Image

 ZOOM: With the input image displayed, rotate the textured ring on
the lens barrel to increase or decrease the image size (this requires a
zoom lens). If you don’t have a zoom lens or you can’t adjust the
image enough, the projector may not be positioned at the proper throw
distance for your screen size. Power down, unplug the projector and
move it towards or away from the screen. See 2.3, Projector Position
and Mounting for details.

 FOCUS: At the lens opening, turn the focus tab to focus the image
clearly.

 OFFSETS: Turn either or both of the adjustment screws (with the
provided hex driver) adjacent to the lens if you need to align the image
with your screen-turn the top screw to raise or lower the image. Turn
the bottom screw to shift the image left or right. Re-check focus.

 OTHER: Press to refine other display parameters as described
in Section 3.

2.2 Installation Considerations

Although this projector delivers a high brightness quality output, final display quality could be
compromised if the projector is not properly installed. This subsection discusses issues you
should consider before proceeding with a final installation. Even if you do not intend to use the
projectors in a fixed and permanent installation, this subsection will help you to better understand
what you can do to enhance display performance.

Lifting

For any new installation, you will likely have to safely lift the projector into place. Keep in mind
that the projector is quite heavy, and the aid of a CO2 or other type of mechanical lift is highly
recommended.

INSTALLATION AND SETUP

Installation Type

Choose the installation type which suits your needs: front or rear screen, floor mount or invert­ed mount.

Screen Type Front Screen Installations

While there are two basic screen types, flat and curved, generally flat screens are recommended
for this projector. Flat screens offer a gain of about 1 with a viewing angle just less than 180°. The
image is diffused equally in all directions so the audience can see the display from various angles.
Because of the low gain, flat screens are most effective when ambient lighting is reduced,
although this difference may be negligible given the high brightness output from this projector.

INSTALLATION AND SETUP

Figure 2.1. Audience Coverage with Flat Screen

NOTE: Lenses for this projector are designed primarily for use with flat screens, but the projec­tor depth-of-field range allows the lens to be focused on curved screens as well. While focus
remains sharp in the corners, there may be significant pincushion distortion, primarily at the top
of the screen.

Rear Screen Installations

There are two basic types of rear screens: diffused and optical. A diffused screen has a surface
that evenly spreads the light striking it. Purely diffused screens have a gain of less than 1. The
main advantage of the diffused screen is its wide viewing angle, similar to that of a flat screen for
front screen projection. Fresnel lenticular screens take light from the projector and redirect it to
increase the light intensity at the front of the screen. This reduces it in other areas. A viewing
cone, similar to that of a curved front screen installation, is created.

To summarize, Fresnel lenticular screens are better suited for brightly lit rooms where the audi­ence is situated within the viewing cone. Diffused screens may be better suited when a wide view­ing angle is required but there is low ambient room lighting.

Screen Size

Screen size may be from 5 to 40 feet diagonal, depending on the lens you are using. For instance,
a 1.2:1 lens can produce a 5 to 25 foot image size, whereas a 4-7:1 zoom lens produces an 8 to
40 foot image size. Choose a screen size that is appropriate for your lens and application. Keep
in mind that if the projector will be used to display text information, the image size must allow
the audience to recognize all text clearly. The eye usually sees a letter clearly if eye-to-text dis­tance is less than 150 times the height of the letter. Small text located too far from the eye may
be illegible at a distance no matter how sharply and clearly it is displayed.

To fill a screen with an image, the aspect ratio of the screen should be equal to the aspect ratio of
the image. The aspect ratio of an image is the ratio of its width to its height. Standard television
has a 4:3 or 1.33:1 aspect ratio. For example, to display a television image with a 4:3 aspect ratio
onto a 10 foot (3m) high screen, the width of the screen must be at least 13.3 feet (4m).

Note: Screen size is often specified as diagonal size. Screens specified by diagonal size have
aspect ratios of 4:3. Screens with other aspect ratios, such as 16:9, are not typically specified by
diagonal size, instead they are specified by height and width.

INSTALLATION AND SETUP

Figure 2.2. Poor Screen Placement

Ideal Room Lighting

The high brightness output of this projector is certainly well suited for locations where ambient
lighting is less than optimum for projection, yet there are still many simple things you can do to
optimize your installation.

Visiting a movie theater can give you an idea of what makes an ideal projection environment.
Walls, floors and furnishings are dark and have a matte finish. A projection room should not have
white reflective ceilings or non-directional lighting, such as fluorescent lights. The white ceiling
spreads light, making the room appear brighter. Keep lighting and reflections to a minimum.

If it is not possible to eliminate fluorescent lights, consider using incandescent spot lighting or
parabolic reflectors (“egg crates”) to direct light down to the floor. Light dimmers or rheostats
allow further control.

Outside windows are undesirable in any projection room. A small crack between curtains on a
sunny day can wash out a projected image. If you do have windows, make sure that window cov­erings are opaque and overlapping - some window coverings are designed to provide up to 100
percent blockage of outside light. Ideally, the material should have a matte finish.

To minimize the effects caused by unwanted light from door and aisle ways, carefully choose the
position of your projector and screen. Figure 2.2 shows an installation where poor screen place­ment allows too much unwanted light to enter the screen. In Figure 2.3, screen and the projector
are positioned so that unwanted light is minimized.

Figure 2.3. Better Screen Placement

2-6

INSTALLATION AND SETUP

Even with all lighting removed it is still possible that room reflections within the room can slight­ly degrade the image. Light from the projection screen should be absorbed by the ceilings, walls
and floors so that it will not be reflected back to the screen. Again, keep reflective surfaces to a
minimum.

Other Considerations

Here are some other considerations and tips which can help you improve your installation:

 Ventilation is an important factor when preparing a projection room. The ambient temperature

should be kept constant and below 35°C (95°F). Keep the projector away from heating and/or
air conditioning vents. Changes in temperature can cause drifts in the projector circuitry that
may affect performance.

 Keep the projector away from devices that radiate electromagnetic energy such as motors and

transformers. Common sources of these are slide projectors, speakers, power amplifiers, ele­vators, etc.

 For rear screen applications, less space is required if a mirror is used to fold the optical path.

 Choose the right screen size for the application:

U As screen size increases, magnification increases and reduces brightness. Select a screen

size which is appropriate for the venue, but not larger than that required.

U Installing a large screen in a small room is similar to watching television close up; too

large a screen can overpower a room. A good rule of thumb is to be no closer than 1.5
times the width of the screen.

U Larger screens require greater attention to lighting conditions.

 When laying out the projection room, consider positioning the projector and screen in a man-

ner that will achieve maximum audience coverage and space efficiency. For example, placing
the screen along the larger wall in a rectangular room will reduce audience coverage. Figure

2.4 shows two examples of how audience coverage is maximized.

INSTALLATION AND SETUP

Figure 2.4. Screen Locations for Maximum Audience Coverage

2.3 Projector Position and Mounting

Installation type, screen type, and lighting all affect where the projector is positioned. In addition,
both throw distance (the distance between the projector and screen) and vertical position (the
height of the projector in relation to the screen) must be determined for every new installation.
Both depend on the screen size and lens type you are using. Make sure that the room can accom­modate the required position of the projector for the chosen screen size.

Throw Distance

Throw distance is the distance between the projector’s front feet and the screen. For any installa­tion, an accurate throw distance must be determined in order for the image to be of the right size
for your screen-the farther the projector is from the screen, the larger the image.

NOTE: If your projector is tilted in relation to the screen, as is sometimes the case for large ven­ues or elevated installations, throw distance still represents the smallest measurement between the
screen and lens.

Throw distance is roughly equal to the hori­zontal width of the screen multiplied by the
type of lens you are using. For example, if
you are using a 0.8:1 lens, proper throw dis­tance will be approximately 0.8 x the screen
width. Once you know your screen size and
lens, you can estimate throw distance needed
(see example in Figure 2.5).

IMPORTANT: For proper placement in an
installation, always refer to the throw
distance formula and/or graph for your lens
as listed in Appendix E. Keep in mind that due to lens manufacturing tolerances for lens focal
length, actual throw distance can vary ±5% between lenses described as having the same throw
ratio.

INSTALLATION AND SETUP

Vertical & Horizontal Position 

THE VERTICAL POSITION of the projector in relation to the screen also depends on

the size of the screen and the lens type. Correct vertical position helps ensure that the image will
be rectangular in shape rather than keystoned (having non-parallel sides) and that image focus and
brightness both remain optimized.

In addition, vertical position of the image can be manually offset-that is, moved up or
down-by turning the top screw on the front of the projector (the bottom screw if the projector is
ceiling mounted). The range of adjustment is roughly 130%, depending on the specific lens you
are using and whether or not you are also offsetting horizontally. See Table 2.1 for the percentage
of the image that can be displayed above and below the center of each type of lens designed for
this projector. These image offsets are also illustrated in Figure 2.6 (fixed lenses) and Figure 2.7.

INSTALLATION AND SETUP

Figure 2.7. Maximum Vertical Offsets (ZOOM LENSES)

NOTES: 1) If you cannot raise or lower the image enough using
mechanical vertical offsets, try adjusting V-Position in the Size
and Position menu (see 3.6, Adjusting the Image). 2) If the image
becomes keystoned or exhibits uneven brightness, the projector
may simply be too high or low in relation to the screen.

3) Recommended offset ranges can be exceeded, however this may
affect image quality. 4) Simultaneous horizontal and vertical
offset limits the adjustment range of each.

THE HORIZONTAL POSITION of the image can be offset-that is, shifted left or right of lens center-by
turning the bottom screw on the front of the projector (the top screw if the projector is ceiling mounted). The
maximum horizontal offsets for the lenses designed for this projector is shown in Figure 2.8. For this projector,
this value expresses the maximum percentage of the image that can be projected to one side of the lens center
(roughly 80%, depending on the lens).

2-10

INSTALLATION AND SETUP

Mounting

For typical front or rear floor mounts, mount the projector on a secure table
or cart. Take care with a mobile cart-avoid sudden stops, excessive force and
uneven surfaces that may cause the projector and cart combination to over­turn.

The table or cart should be reasonably level. Fine adjustments to the projec­tor level can be made by adjusting the height of the projector legs; refer to 2.7,
Leveling for details.

Special Mounting

Note that projector can be rotated and mounted at any vertical angle-i.e., you can tilt the face of
the projector up or down as much as desired for your installation. The side-to-side tilt, however,
must not exceed 15° (see Figure 2.9). This limit ensures that the arc lamp in the projector oper­ates properly and safely. Always make sure that exhaust air from the projector does not vent
towards the lens, otherwise you may detect heat waves in your projected image.

Figure 2.9. Horizontal and Vertical Tilt Ranges

You must use the proper ceiling mount fixture or stacking kit for your projector. For more infor­mation, contact your Runco dealer.

INSTALLATION AND SETUP

Folded Optics

In rear screen applications where space behind the pro­jector is limited, a mirror may be used to fold the opti­cal path. The position of the projector and mirror must
be accurately set-if considering this type of installation,
call your Runco dealer for assistance.

2.4 Source Connections

The rear panel of the projector provides standard input panels to which you may connect a vari­ety of sources. See Figure 2.10-the lower left area (INPUT 1) typically accepts an RGB signal
from an external RGB source (such as the VHD Ultra Controller), or it can also be used for YPbPr
signals from DTV sources. The upper right panel-the Video Decoder Module-accepts only com-
posite video at INPUT 3 or S-video at INPUT 4 from devices such as VCRs, laser disc players
or DVD players. There are also several optional interfaces available for connecting other sources
at INPUT 2. Such an option installs in the upper left area, just below the audio connectors. For
any input, including the optional inputs, audio with loop through connects at the audio input panel
located between the license label area and INPUT 2.

Figure 2.10. Rear Connector Panel

Note: The decoder module is an option; it is not supplied with the Projector.

INSTALLATION AND SETUP

RGB Signals

INPUT 1 provides 5 BNCs (connectors) for linking to a variety of sources. The typical connec-

tion would be to an RGB source such as the VHD Ultra Controller, computers or DTV decoders
with an RGB output. This projector supports multiple sync types with RGB signals: sync-on­green, composite sync, and separate H & V syncs.

NOTES: Depending on the source, you may need a custom adapter cable that has BNC connec­tors at the projector end and a different type of connector at the other (such as a 15-pin “D” con­nector for computer sources). Contact your Runco dealer.

Connect the SYNC BNC input(s) first. Then connect the red, green and blue source outputs to the
RED, GREEN, and BLUE BNCs on the INPUT 1 panel. If the source uses sync-on-green, only

the red, green, and blue connections are required. If the source provides a composite sync output,
connect it to the SYNC input labeled HOR/COMP. If the source provides separate horizontal
and vertical sync outputs, connect horizontal sync to the SYNC input labeled HOR/COMP and
connect vertical sync to SYNC input labeled VERT. See Figure 2.11.

NOTE: To connect YPbPr signals, such as from analog HDTV sources, to INPUT 1, use the red,
green and blue BNCs as described in YPbPr Signals later in this section.

Figure 2.11. Connecting RGB Input

AUDIO for INPUT 1: To control audio levels in an audio/visual system, connect pre-amplified (line level)
audio inputs to the “IN 1” left and right channel audio inputs located near the top left corner of the rear input
panel. Then connect external audio amplification equipment to audio “OUT” for sound output. Audio connec­tion cables require standard RCA type phono plugs.

INSTALLATION AND SETUP

YPbPr Signal (COMPONENT VIDEO)

Connect a YPbPr signal (component video) to INPUT 1 as shown in Figure 2.12.

Figure 2.12. Connecting YPbPr Signal

NOTES: 1) If, for some reason, the projector fails recognize a YPbPr signal, specify this Color
Space option within the Image Settings menu. See 3.6, Adjusting the Image. 2) Do not connect

digital component signals (known as YCbCr) to INPUT 1. Use the appropriate digital interface
installed at INPUT 2.

AUDIO for INPUT 1: To control audio levels in an audio/visual system, connect pre-amplified
(line level) audio inputs to the “IN 1” left and right channel audio inputs located near the top left
corner of the rear input panel. Then connect external audio amplification equipment to audio

“OUT” for sound output. Audio connection cables require standard RCA type phono plugs.

2-14

INSTALLATION AND SETUP

Composite Video

The video decoder input panel provides simultaneous connection of both a composite video
source (INPUT 3) and an S-Video source (INPUT 4).

If connecting a composite video source, use the Composite BNC connector or the RCA phono
jack at -do not use both as inputs. See Figure 2.13.

AUDIO for INPUT 3: To control audio levels in an audio/visual system, connect pre-amplified
(line level) audio inputs to the “IN 3” left and right channel audio inputs located near the top
left corner of the rear input panel. Then connect external audio amplification equipment to
audio “OUT” for sound output. Audio connection cables require standard RCA type phono
plugs.

NOTE: If you want to loop a composite video signal through to another projector or display
device, see Video Loop Through later in this section.

INSTALLATION AND SETUP

S-Video

The video decoder input panel provides simultaneous connection of both a composite video
source (INPUT 3) and an S-Video source (INPUT 4).

If connecting an S-Video source, use the 4-pin mini DIN connector or the Y and C BNC con­nectors (luma and chroma) at INPUT 4-do not use both as inputs. See Figure 2.14.

NOTE: If you want to loop an S-video signal through to another projector or display device, see
Video Loop Through.

2-16

INSTALLATION AND SETUP

Video Loop Through 

To loop a single incoming video signal input (connected at the video decoder) through to anoth­er projector or display device, use the empty connector(s) adjacent to this same input as described
below.

Composite Video Loop Through
CONNECTIONS: See Figure 2.15. From your source, connect a composite video signal to
INPUT 3 using either the small phono plug or the adjacent BNC. Connect a second cable from

whichever INPUT 3 connector is free to one of the composite video inputs of the next display
device or projector. Continue this looping method for each projector, using either the phono plug
or the adjacent BNC as input into INPUT 3, then using the other connector as an output (i.e.,
loop through). Whether you use the BNC or the phono plug as input or output depends on the type
of cable you have on hand and what type of connectors are on each end. If desired, connect one
audio signal to any projector as usual.

VIDEO TERMINATION: In the Preferences menu, make sure “Video Termination” is checked
for the final projector only. All other projectors must have this option unchecked in order for the
signal to continue. For other types of display devices in the chain, typically a “Hi-Z” switch posi­tion is needed.

INSTALLATION AND SETUP

S-Video Loop Through
CONNECTIONS: See Figure 2.16. From your source, connect an S-video source signal to
INPUT 4 using either the 4-pin mini DIN or the 2 adjacent BNCs labeled Y and C. Connect a

second cable from whichever INPUT 4 connector is free to one of the S-video inputs of the next
display device or projector. Continue this looping method for each projector, using either 4-pin
mini DIN or the 2 adjacent BNCs as input into INPUT 4, then using the other connector(s) as an
output (i.e., loop through). Whether you use 4-pin mini DIN or the 2 adjacent BNCs as input or
output depends on the type of cable you have on hand and what type of connectors are on each
end. If desired, connect one audio signal to any projector as usual.

VIDEO TERMINATION: In the Preferences menu, make sure “Video Termination” is checked
for only the final projector. All other projectors must have this option unchecked in order for the
signal to continue. For other types of display devices in the chain, typically a “Hi-Z” switch posi­tion is needed.

 HDTV Serial Input Module (available Spring 2000)

2-19

INSTALLATION AND SETUP

2.5 Power Connection

Plug the projector’s high-current 13-amp rated line cord into the line input socket located in the
lower right corner of the rear panel of the projector, then plug the 3-pronged end of the line cord
into a grounded AC outlet. Input voltage to the projector must be capable of supplying between
100 and 240 VAC, 50 or 60 Hz. The power source must be capable of supplying 1200 watts of
power to the projector. See Section 5, Specifications for all power requirements.

WARNING

Do not attempt operation if the AC supply and cord are

not within the specified voltage and power range.

Caution: Once the projector is turned off, the lamp cooling fans will continue to run for
approximately five minutes to ensure that the projector and lamp have sufficiently cooled, at
which point the fans will automatically shut off. To avoid thermal stress to the lamp, never unplug
the line cord while the lamp cooling fans are running. Do not unplug the projector in order to
power down.

2.6 Operating Orientation

The projector is set up at the factory for use in a front screen, floor mount orientation. If your ini­tial installation is ceiling mount or rear screen, displayed images may be upside down and/or
reversed. To correct, you must change the
image orientation from within the Preferences
menu (you may prefer to do this before physi­cally installing the projector in its final posi­tion/orientation).

In the Preferences menu, highlight and select
the “Image Orientation” pull-down list. Select
from Rear, Inverted Rear, Front or Inverted
Front according to your intended installation.
See Section 3, Operation for further informa-
tion.

2.7 Leveling

For most installations, the lens surface of the
projector is parallel to the screen-this prevents
‘keystoning’ of the image (i.e., an image with
non-parallel sides). In addition, the projector
must be kept level from side-to-side in order for
the lamp to function safely. To make small cor­rections to the projector’s level, rotate each leg
as necessary to raise or lower. For angled instal­lations, see “Special Mounting” under 2.3,
Projector Position and Mounting earlier in this
section.

INSTALLATION AND SETUP

2.8 Zoom, Focus & Lens Offset

Once the projector is properly set up and producing an image, you are ready to make quick lens
adjustments.

Zoom

If you have a zoom lens installed, turn the textured ring of the lens barrel to decrease or increase
the size of the image at the current throw distance. NOTE: Do not touch the lens surface.

Focus

At the lens opening, turn the focus tab until the image is as sharp as possible.

Lens Offset

To ensure that the image is located as desired, turn either or both of the front screws next to the
lens. The top screw (vertical) will raise or lower the image, the bottom screw (horizontal) will
shift the image left or right. Try to achieve the desired overall image position and best brightness
while obtaining a rectangular image. If the brightness looks uneven, or the edges do not look per­fectly straight, the projector may not be in the optimal position for your screen. See 2.3, Projector
Position and Mounting for full details. Lens offset ranges are also listed on page 5-1.

Further display adjustments are available through keypad commands and on-screen menus-refer
to Section 3, Operation.

2.9 Serial Port Connections

You may wish to use equipment other than the keypad for controlling the projector or for per­forming other special functions. Such equipment-such as most personal computers-requires a
serial interface for sending and receiving communications through the serial ports on the projec­tor. Note that there are two different types of serial communication ports on this projector as
described below.

If using a computer

RS-232 Ports

From computers or automation systems, connect an RS-232 serial communication cable between
the controlling device and the projector serial port labeled RS-232 IN-this 9-pin D connector port
is located near the bottom center of the projector’s rear control panel (see Figure 2.19). Then set
the projector baud rate to match that of the computer or automation system(changing the baud rate
is described in 3.7, Adjusting System Parameters and Advanced Controls).

NOTE: Refer to Appendix D for complete cable wiring details.

2-21

INSTALLATION AND SETUP

Figure 2.19. RS-232 Serial Connection to a Computer

RS-422 Ports

Some systems can provide RS-422 serial communications (often through a plug-in adapter or
external converter) rather than the more common RS-232. RS-422 communication has differen­tial “transmits-and-receives” and is generally better suited for long distances than is RS-232 com­munication. RS-422 is not compatible with RS-232-connecting one to the other could damage the
equipment at either end.

If you wish to control the projector with a computer and/or other controlling device having RS­422 capability, connect RS-422 serial communication cables between the computer (or other
device) and either (or both) of the projector serial ports labeled RS-422-these 6-pin XLR con­nector ports are located near the upper right corner of the projector’s rear control panel (see Figure

2.20). Use an RS-422 port only if your equipment has RS-422 capability-always first consult the
documentation supplied with your equipment.

2-22

INSTALLATION AND SETUP

WARNING

Do not use an RS-422 port unless you are using a computer with RS-422 capability.

The voltage levels of this signal can damage incompatible equipment.

If using multiple projectors

Serial Communications
RS-232 NETWORK: To control multiple projectors with a computer/controller having an RS-

232 interface, chain the projectors together by connecting the RS-232 OUT connector of the first
projector (already connected to the computer/controller) to the RS-232 IN connector of the next
projector in the chain.

2-23

INSTALLATION AND SETUP

RS-422 NETWORK: To control multiple projectors with a computer/controller having an RS-

422 interface, you can chain the projectors together by connecting the RS-422 PORT 2 connec­tor of the first projector (already connected to the computer/controller) to the RS-422 PORT 1
connector of the next projector in the chain.

Figure 2.22. Adding Another Projector via RS-422

For either type of network, continue connecting projectors in this manner until you’ve reached the
last projector in the chain, so that only the last projector has an empty RS-232 OUT (or RS-422

PORT, if applicable). See examples on the following page.

2-24

INSTALLATION AND SETUP

Figure 2.23. Assorted Networks

Communication parameters such as baud rate must be set to match the particular controlling
device-refer to the documentation that came with your controlling device in order to determine
the proper baud rate. See 3.7, Adjusting System Parameters and Advanced Controls if you need
help changing the projector baud rate from its default of 38400.

NOTES: 1) To avoid damage, connect only properly wired serial communication cables. See
Appendix D for details. 2) It is recommended that each RS-232 communication cable be no more

than 25 feet in length. Use high quality cables.

INSTALLATION AND SETUP

Projector Numbers

Each projector can be assigned a unique 3-digit projector number (for example, 001). These num­bers are particularly useful when you are working with multiple linked projectors, enabling you
to direct commands to a certain projector rather than always broadcasting to the entire network.
For complete information on how to assign projector numbers, see 3.7, Adjusting System

Parameters and Advanced Controls.

NOTE: To loop a single incoming video source through to another projector or display device on
a network, see Video Loop Through in 2.4, Source Connections.

2.10 Keypad Protocols and Conversion

At manufacture every keypad is assigned “A” as its default protocol, which is simply a collection
of settings that determine how the keypad operates. Once assigned, this protocol remains in effect
until it is changed-that is, the keypad will operate as it currently does until you change its proto­col.

Protocols are most useful for multiple-projector applications. For example, you might want to
change a keypad protocol if you are working with two projectors and two remote keypads in the
same room and need to control each projector independently (Figure 2.24). When Keypad A has
a different protocol than Keypad B, each keypad communicates only with the projector having a
matching protocol. Or, if you have a network of two or more projectors connected together via
RS-232 serial ports, you may want only certain projectors to respond to a wired keypad, thus you
can use different protocols to limit responses.

NOTE: Matching the protocol on the projector to that of a keypad is done through a setting in the
Communications menu. See 3.7, Adjusting System Parameters and Advanced Controls for fur-
ther information on how to change the projector’s infrared sensor (rear and front) protocol.

A protocol for either type of remote keypad - IR or wired - can be changed through software com­mands entered on the keypad. A new protocol set through software commands remains in effect
until the keypad batteries are removed and replaced (if an IR remote), or until the keypad is
unplugged (if a wired remote). A remote can also be changed manually -you can “hard-wire” new
jumper settings inside the keypad so that they remain in effect until you change the hard-wiring.
Note that a hard-wired protocol can be temporarily overridden by the software protocol change,
effective until the keypad is unplugged and plugged in again (if a wired remote) or until a battery
is removed (if an IR remote).

2-26

INSTALLATION AND SETUP

Figure 2.24. Independent Keypads and Projectors

Remote Keypad Protocol - IR OR WIRED KEYPAD -

The standard IR remote keypad or the optional wired remote can be set to one of two
different protocols - “A” or “B”. To hard-wire a protocol to “A” or “B” in either remote,
follow Steps 1 through 5:

Step 1

Unplug the keypad from the projector (applies to wired remote only).

Step 2

Unlatch and open the empty battery compartment on the back of the keypad as shown in Figure

2.25.

NOTE: A wired keypad opens as shown, but a cable passes through the battery compartment
cover.

Figure 2.25. Opening the Keypad

Step 3

Find the 4 jumpers located along the latching side of the battery compartment. These jumpers set
the keypad protocol and other settings so that the keypad functions in a certain manner.

Step 4: Set the Jumpers

Set the jumpers as shown in Figure 2.26. Take care to refer to the correct part of the drawing - IR
or wired (optional). Use tweezers or needle-nose pliers to remove and replace each jumper as
necessary.

2-27

INSTALLATION AND SETUP

 J1 jumper: For either remote, set between pins 1 and 2 to set as Protocol “A”. Set between

pins 2 and 3 to set as Protocol “B”.

 J2 jumper: For either remote, set between pins 2 and 3 as shown; otherwise, the projector

will not respond correctly to keypad commands.

 J3 jumper: For the IR remote, make sure that the jumper is set between pins 2 and 3 as

shown. For the wired remote, make sure that the jumper is set between pins 1 and 2 as

shown.

 J4 jumper: For the IR remote, make sure that the jumper is set between pins 1 and 2 as

shown. For the wired remote, make sure that the jumper is set between pins 2 and 3 as

shown.

Step 5

Replace battery compartment cover. Plug into projector (wired keypad only) and test.

Figure 2.26. Locating and Setting the Jumpers

NOTE: A wired keypad can be converted into an IR remote keypad, and vice versa. Follow the
settings shown above, adding or deleting the cable and batteries as required. The cable with 3­pin XLR connector is available separately from your dealer.

SHORTCUT METHOD:

You can also issue software protocol settings through the keypad. These software commands
will be lost when the keypad is either unplugged or when a battery is removed - the keypad will
revert back to the hard-wired jumper settings (see above) until you enter the software com­mands again.

INSTALLATION AND SETUP

NOTE: If you change any keypad to a new protocol and the projector stops responding, the
projector may be set to a conflicting protocol. Use the projector’s built-in keypad to access the
Communications menu. Under “Front IR” or “Back IR” or “Wired Keypad”, select the protocol
that matches the new protocol of the keypad at hand. The projector should now respond
properly.

Converting a Keypad

If desired, you can convert an IR remote keypad into a wired remote keypad and vice versa.

TO CHANGE FROM INFRARED TO WIRED:

 Remove battery compartment cover from back of keypad.
 Remove batteries.
 Wait 1-2 minutes.
 Plug the keypad cable (available separately) into the empty battery com-

partment. Make sure that the battery cover is notched smoothly to accom­modate the cable.

 Set keypad protocol as desired, using “wired” jumper settings.
 Replace battery compartment cover.
 Plug into the 3-pin XLR port at the rear panel of the projector.

3.1 Overview

This section explains how to use the projector once it has been installed. Please read through these
pages before using the projector for the first time. An understanding of projector features and how
to access them will help you to take full advantage of the capabilities of the projector within min­utes.

NOTE: Installation involves locating the projector and adjusting it for use at that location. If you
have not yet installed the projector, refer to Section 2, Installation and Setup.

3.2 Projector Basics

Most projector functions and adjustments are entered through keypad commands that either con­trol the projector directly or activate a system of intuitive menus. Variations in settings can be
defined and retained in the projector’s internal memory as a custom channel, with up to 99 dif­ferent channels possible.

AC LINE CORD INPUT - The projector requires AC power of 100 to 240 VAC, 50 to 60 Hz
(11.5 amps @ 100 VAC, 5.5 amps @ 220 VAC). Always use the line cord that is supplied with
the projector-the projector requires this high-current 13A rated cord. See complete power speci­fications in Section 5.

WARNING

Do not attempt operation if the AC supply is not

within the specified voltage and power range.

STATUS/POWER LEDS - Two LEDs (light emitting diodes) located in the lower right corner of
the rear connector panel indicate projector “Status” (top) and “Power” (bottom). During normal
operation, the “Power” light is steady green and the “Status” light flashes green each time a key
is pressed or when the projector receives a serial command. Use the following as a guide:

Figure 3.2. Reading the Status LEDs

NOTE: A steady red power light accompanied by a coded pattern of red and yellow flashes from
the status light indicates an internal system error. Consult the rear LCD display for an explana­tion, and see 3.9, Error Conditions. Should the problem persist, contact your Runco dealer.

REMOTE WIRED KEYPAD CONNECTOR (3-pin XLR) - For optional tethered remote control
of the projector.

LCD STATUS DISPLAY - Visual feedback for monitoring projector activities and status.

INFRARED SENSORS - The infrared (IR) sensors on the front and rear of the projector receive

infrared signals from the IR keypad for remote control of projector functions. For proper opera­tion make sure that these sensors are not blocked.

HARD RESET - Emergency access for powering down the projector in the event of a system
failure. Insert a pen point or small screwdriver.

OPERATION

3.3 Using the Keypad The keypad appears in two locations:

 Infrared (IR) Remote for wireless control up to 100 feet away
 Wired Remote (optional) tethered to the rear of the projector

While each keypad is identical in layout and provides complete control of the projector, you may
find one keypad more convenient than another for your specific installation and application.

IR Remote

The IR Remote Keypad controls the projector by way of wireless communications from a battery­powered infrared (IR) transmitter. Use the IR remote keypad the same way you would use a
remote keypad supplied with a TV or VCR. When making key presses, point the keypad either
toward the screen or toward the front or rear of the projector. One of two sensors on the projec­tor will detect the signals and relay the commands for internal processing.

Wired Remote-OPTIONAL-

The wired remote keypad connects to the 3-pin XLR jack via a 50 ft. cable. It is recommended
when:

 the lighting conditions are unsuitable for proper IR transmission
 you want to use a separate keypad for each projector in a group

Guide to Keypads

Keep in mind the following guidelines:

1) Press keys one-at-a-time; there are no simultaneous key presses required.

2) For any key having an “*”( for example), hold the key for approximately 1 second in

order to toggle the function with a single key press. For other keys (or to use a “*” key in con­junction with ), a momentary press similar to a mouse click is sufficient.

3) Press the “lightbulb key” to temporarily illuminate the backlight for the keys without sending
any other command.

4) , , , and repeat their “arrow” actions when held down. For other keys,
release and press again to repeat an action.

5) If you press a key while the projector is busy with another action, such as during a power-up,
the key press may not take effect.

Keypad Commands

Specific keypad commands are explained below:

Power ON/OFF

Press and hold for approximately 1 second to turn the projector on or off with a single key press.
Or press followed immediately by or if you want to guarantee the correct toggle
(useful if you are unsure of the present status).

NOTES: 1) Whenever the projector is turned off, the lamp cooling fans remain on for about five
minutes to cool the lamp. 2) It is a good idea to avoid turning a projector back on until it has been
off for a few minutes. Hot re-strikes of the lamp may reduce lamp life.

assigned to your switcher (usually 1-9, or "0" for one of the four inputs on the projector). The sec­ond digit represents the switcher's slot number (1-9). For example:

= display data from switcher 1, slot 2.

NOTES: 1) Although you don't need to use the input key, you can also use to access the four
input "slots" on the projector itself: use as the first digit (representing the projector as the
switcher), then , , ,or as the second digit (the desired input slot number). in combi­nation with higher numbers is an invalid entry. 2) See 3.5, Using Channels and Inputs for a
detailed explanation of inputs.

NOTE: key behavior during a presentation depends on whether or not the Display Channel
List option is selected in the Preferences menu. You can choose to have on-screen feedback when
you press , or you may prefer to enter the desired source location "blind", i.e., without on­screen feedback. See Preferences later in this section.

Channel

Press to select a specific source setup (channel) defined and stored in projector memory.
Once you enter a 2-digit channel number (or, if there is a list displayed, highlight it and press

), the display will automatically change and update according to the numerous setup param-

eters defined for that channel.

NOTE: key behavior during a presentation depends on whether or not the Display Channel
List option is selected in the Preferences menu. You can choose to use a scrollable list of chan-

nels when you press , or you may prefer to enter the desired channel number "blind", i.e.,

NOTE: does not save changes within text editing boxes (including number editing of a
slidebars) or within pull-down lists. It acts as a "cancel" in these cases.

Arrow Keys

The arrow keys have a variety of functions depending on the situation. Some typical uses are
described below. See also Editing Text later in Section 3.

 Use or to change a slidebar value-hold as desired for contin-
uous adjustment (note the adjustment increments and range depend on the
parameter being adjusted).

 Use or to change to a different option within a pull-down list
without having to display the list first.

 Use or to jump between "pages", such as in Help or lengthy
pull-down lists.

Use the keys to navigate within a menu, pull-down list or text box, or to increase
decrease the value in the second (bottom) slidebar of a double slidebar.

You can also use in conjunction with certain toggle keys-i.e., those including an
asterisk symbol-to ensure a toggle only in the desired direction. When turning the projector on,
for instance, you may be too far from the projector to know whether it is really off or if the
shutter is merely closed. If you press and hold it for approximately 1 second in hopes of
turning the projector on, the projector will actually turn off if the projector was already on.
Instead, to avoid the risk of toggling in the wrong direction, quickly press and release normally
the function key you wish to toggle (in this case ). Then immediately (within 2 seconds)
press either as desired. The specific toggle will occur.

Toggle keys are labeled with an asterisk on the keypad. They are listed below:

 + = close the shutter (OPTIONAL)

+ = open the shutter (OPTIONAL)

 + = put the projector in standby mode

+ = leave standby

Color

Press to adjust the color saturation level, i.e. the amount of color in a video image. Lower
settings produce less saturated colors - a setting of "0" produces a black and white image, for
example. If the color level is too high, colors will be overpowering and unrealistic. Use
and until the desired color saturation level is displayed. This is not used when an RGB
source is input.

Tint

Press to adjust the red/green color hue for true color reproduction of NTSC video signals.
For best results, adjust tint while displaying a proper test pattern - otherwise, it is recommended
that tint remain at its default setting. Use and until the desired tint is displayed.
This is not used when an RGB source is input.

Detail

Press to adjust the sharpness of a video image (it is of limited use for non-video). Use

and until the display is as sharp as desired, keeping in mind that any level of detail
above 3 will also introduce a certain degree of noise in the image. Set below 3 to filter the sig­nal and remove noise from a noisy source. This is not used when an RGB source is input.

Contrast

Press to increase or decrease the difference between light and dark areas of your image.
Use and until you reach the desired level of contrast, making sure that the whites
remain bright but not distorted or tinted (i.e., "crushed").

Brightness

Press to increase or decrease the amount of perceived light in the image so that black just
changes to very dark gray. Use and until you reach the desired level. See 3.6,
Adjusting the Image (Image Settings subsection). Avoid "crushing", or distorted blacks and/or
whites.

Volume

Press to control the audio level. Use and until you reach the desired volume.

Projector

Press when you want to access a specific projector within a group or if you simply need to
see if the local projector is listening. The number appearing in the "Enter Number" window
indicates which projector is currently listening to commands, and will match the projector num­ber that has been defined in its Preferences menu.

The "Projector" checkbox (read-only) shows whether or not the projector physically connected
to a keypad is listening to commands from that keypad. A checkmark means that connected
projector is listening; if there is no checkmark, you are communicating with a different projec­tor.

remaining projectors. See 2.10. Keypad Protocols and Conversion, and 3.7, Adjusting System

Parameters and Advanced Controls.

Pixel

Press to access the pixel tracking and pixel phase double slidebar. Adjust pixel tracking
first: use and to increase or decrease the frequency of the pixel sampling clock to
correct consistency of the image. For proper phase, use and to increase or decrease
pixel phase so that any shimmer disappears and the image is stable throughout. See 3.6,
Adjusting the Image (Size and Position subsection) for a complete explanation of tracking and
phase.

Position

Press to move the image using the double slidebar. At the slidebar, use and to
move the image left or right, use and to move the image up or down.

Shutter (OPTIONAL)

If your projector has a mechanical lens shutter (a.k.a. dowser) installed, press and hold
for approximately 1 second to toggle the shutter closed or open with a single key press (this
also blanks the image electronically). Or quickly press and release and follow immediately
with or if you want to guarantee the correct toggle (useful if you are unsure of the
present status). Close the shutter whenever you want to mute all display yet maintain access to
projector functions. Open the shutter to regain the display. With no shutter installed, still
blanks the image electronically, but the blanking is not quite as black.

NOTES: 1) The status of the shutter is shown in the LCD window on the rear panel of the pro­jector. 2) Upon power-up, the shutter is open. 3) The lamp remains on.

Mute

Use to mute audio and/or hide the current menu. Press and hold for approximately
1 second to toggle the audio on or off with a single key press. Or quickly press and release

channels (source setups), switchers, or slots. As each digit is entered, it is displayed and the
cursor moves on. Note that channel numbers are defined with 2 digits-for example, if you enter
only a single digit (like "7") for a channel number, the channel will automatically be defined as
"07". Use "07" to utilize this channel.

NOTES: 1) Once you enter the first digit, this digit replaces all old digits. 2) If you press any
non-numbered key, the number entered up to that point is accepted and updated as the new
value. 3) Press to cancel editing of numerical values.

3.5 Using Inputs and Channels

NOTE: See Section 2, Installation and Setup, for a full explanation of how to connect a variety
of sources to the projector.

The projector stores and automatically recalls up to 99 different channels (source setups) for a
variety of inputs. This memory feature allows you to define and conveniently use a wide variety
of customized setups rather than having to repeatedly re-configure the projector for different
presentations. Each physical source (i.e., input) can have several different channels associated
with it.

Selecting an Input 

INPUT - An input simply describes a physical location for an incoming signal connection.

These connections are always either on the projector itself (one of the four inputs at the rear of
the projector).

EXAMPLE:

` = use source connected to the projector, slot #1 (i.e., )

Pressing the appropriate direct key - , , , or - is a quick and seamless way to
display from one of the four inputs connected at the rear of the projector.

If it is the first time you have used the source/input (or if you used the input but did not define
a channel by adjusting anything ), the projector will recognize the new input signal based on its
frequencies and polarities, and will automatically display an image according to default settings
for such a signal. Note that a graphic source will resize into a full-screen image, whereas video
or HDTV sources will resize only as much as possible while maintaining their aspect ratio.

If you used the source once before and changed a display parameter such as contrast, V­Position etc., then a channel was automatically created and still exists in projector memory (see
below). Using an key will automatically recall this channel-and all its setup parameters­and update the display accordingly.

If more than one channel exists for the input, the image will be displayed according to the
setup parameters for the first channel with matching characteristics.

OPERATION

CHANNEL - A channel is a collection of measurements, locations and settings that tailor a dis-

play to your specific needs. Since source types and applications can vary greatly, you will likely
want to adjust and define a wide variety of parameters, such as brightness, contrast, tint, size,
etc., in order to customize and optimize the display coming from a particular source. For exam­ple, the display settings you choose for a VCR source may be very different from those you
choose for a high resolution computer source, or one signal may simply vary from another sig­nal used earlier through the same input location. Once you have adjusted a display parameter,
such as pixel tracking or contrast, all current settings are collectively stored in the projector's
memory as a unique 2-digit channel, such as . You can have numerous distinct channels
available for the same input, any of which can be selected by using the key on the keypad fol­lowed by the 2-digit channel number.

NOTE: The key may display a channel list or not, depending on what you have defined
within the Preferences menu (see Preferences later in this section). Shown at right is a sample
channel list available from .

In order to use channels ( on the keypad), you must first create them. See below.

Creating a New Channel  - AUTOMATIC -

To use a new source with the projector, a new channel must be added to projector memory so
that the projector will respond properly to an input signal from that source in the future. A new
channel can be created automatically, as described here, or it can be copied from an existing
channel and then edited as necessary (see Copying or Deleting Channels later in this section).

When you select a direct input (press or , , , or ), the existing channels
in the projector are searched for matching input and signal parameters. If no match to the
incoming input signal is found in the currently defined channels, a new channel is temporarily
created based on factory-defined defaults for this signal. The channel number assigned to this
channel is the lowest available number from 01-99.

NOTES: 1) An automatic channel will be discarded unless one or more of its parameters are
changed, and will not appear in the Channel List (see below). 2) If two channels have the same
distinguishing source characteristics except for the reversal of sync connectors (i.e., H-sync and
V-sync, are switched), they are still defined as distinct channels. 3) You cannot define a new
channel without a signal present.

If the incoming signal does match an existing channel, the image will be set up and displayed
as usual according to the parameters currently defined for that channel.

select a channel at any time by pressing
(see right). If you want to prevent a channel
from appearing in this list, you must edit the
channel as described in Channel Edit later in this
section. Such a channel can still be selected by
entering its number as shown at right.

NOTE: 1) The current channel is highlighted upon entering the Channel List, or, if this channel
is not displayed in the list, the first channel in the list is highlighted. 2) Channels created auto­matically do not appear in the Channel List unless a parameter has been changed.

What Channels Are Defined So Far? 

All available channels are listed in the Channel Setup menu, which describes how each channel
can be accessed and which serves as the gateway for editing, copying and deleting channels.

Press to display the Main menu. To display
the Channel Setup menu, press , or move the
highlight to the Channel Setup option and press

. The Channel Setup menu will appear
(see sample at right), with the active channel
highlighted.

This menu lists all channels defined so far and
indicates how they are connected to the projector.
The far left column contains current channel
numbers defined. The values in the far right
columns indicate horizontal and vertical frequen­cies-if a name has been defined for this channel,
it appears here instead. Other columns contain details pertaining to each channel setup, such as
its switcher number, slot location and a variety of icons indicating access to the channel. See
Editing a Channel Setup for details.

If you have more than a handful of channels, use and to see the remaining channels
not visible in this initial display.

To copy, delete or edit any of the channels listed in the Channel Setup menu, highlight the desired
channel and do one of two things:

·

 Press if you want to copy the selected channel or delete this or other
channels. See Copying or Deleting a Channel below.

 Press if you want to edit channel setups (i.e., non-image related
parameters) for the selected channel. See Editing a Channel Setup, below.

Copying or Deleting Channels 

TO COPY A CHANNEL, highlight the desired channel in the Channel Setup menu, then press

to go to the Channel Copy/Delete submenu. Select "Copy" and press -a new channel
will be created. It is identical to original, which still remains, but it is identified with the next
available number from 01-99. If you change your mind and do not want to copy the current
channel, press to cancel and return to the previous menu. Copying channels is a quick
method for creating numerous channels, each of which can then be edited and adjusted for a
variety of presentations in the future.

TO DELETE A CHANNEL, highlight the desired channel in the Channel Setup menu, then
press to activate the Channel Copy/Delete submenu. Select "Delete" and press -a
confirmation window will appear to make sure that you really want to delete this channel.

Figure 3.9. Deleting a Channel

TO DELETE MULTIPLE CHANNELS, highlight any channel in the Channel Setup menu
and press to go to the Channel Copy/Delete submenu. Select "Delete Unlocked Only" and
press to delete all unlocked channels. Or select "Delete All Channels" to delete all chan­nels, even those that are locked. In either case, the current channel will remain but will be rede­fined from projector defaults.

NOTE: For any deletion, a confirmation box appears to make sure that you really want to
delete. Select "Cancel" (default) if you don't want to delete after all.

can be up to 12 characters in length.

 CHANNEL NUMBER: A channel number from 01 to 99 can be changed here. NOTE: If you enter a
channel number that already exists, a dialog message appears indicating that this number is already in
use-assign a different channel number.

 SWITCHER NUMBER: "0" represents the projector itself. This will likely always be the case for
the VX-5c.

 SLOT: 1 ( ), 2 ( ), 3 ( ) , or 4 ( ) for projector inputs.

 LOCKED: If checked, all of the image settings for this channel are disabled. If unchecked (default),

all available image settings can be adjusted as desired.

 IN MENU: If checked (default, except for automatically defined channels with unchanged parame-
ters), this defined channel will then appear in the list available when key is pressed. If unchecked, the
channel must be accessed via on the keypad or via the Auto Source function. NOTE: On-screen dis-

play of the channel list is an option that must be set in the Preferences menu.

 AUTO SOURCE: If checked, (default), the projector can automatically locate this channel when an
incoming input signal matches. If not checked, the projector can locate the selected channel only when it
is directly selected via on the keypad-and a change in input signal will not result in a channel change.

3.6 Adjusting the Image

Most options for image adjustments can be accessed through two menus: Size and Position
( ) and Image Settings ( ), both of which are listed in the Main menu.
While in either of these two menus, you can change settings affecting the image from the cur­rent channel by working with the appropriate slidebars, checkboxes and pull-down lists.
will always return to the previous menu (or to the presentation, if from the Main menu) and
accept any changes you may have made.

From your presentation, you can access any of the individual options in these menus by press­ing followed by the appropriate two-digit number representing their location in the menu
system. For example, press to quickly access the "color temp" option in the
Image Settings menu.

Note that for certain options, you may prefer to use a "direct key" from presentation level to go
directly to a particular option rather than traveling through the menu system at all (note: this is
not available for all display parameters). For example, press to access the "contrast"
slidebar immediately. Press to return to your presentation.

NOTE: 1) To hide the "direct" slidebars only, make sure the Display Slidebars option in the
Preferences menu is unchecked. 2) To hide the entire menu system from view, toggle the on­screen display OFF: press and hold the key.

Auto Setup

If you want the projector to quickly set up the image for you, select "Auto Setup" from the
Main menu. A confirmation box will ask if you really want to continue, in which case display
parameters listed in the Table below will be set for you. An "Auto Setup" can save time in set­ting up an image, and you can also make further adjustments as desired.

Image Size and Position

The Size and Position menu allows you to increase or
decrease the size of your image, change its proportion
(aspect ratio), move the image to a specific area of the
screen, and refine other related parameters. Use Size and
Position controls to match the image precisely to the
screen size and aspect ratio needed for your application.

Refer to "Using Slidebars and Other Controls" (earlier in
this section) if you need help using any of the following

slidebars or pull-down lists to alter your image.

Resize Presets

Use Resize Presets to quickly display an
image in its native resolution (including
anamorphic) or to automatically resize an
image to fill the screen. The value for Size,
Position and Blanking parameters (described
below) will, in turn, change as necessary
without your having to set them manually.

 DEFAULT SETTING: When displaying a new source, the default “Full Screen”
option is in effect, meaning that your image will fill the screen as fully as possible for
the type of source present:

* A graphic image will resize to fill the screen, regardless of its original aspect
ratio.
* A video image will resize to fill the screen as closely as possible while still
maintaining its aspect ratio. Since a video image is not precisely 4:3, there will
likely be a handful of unused “border” pixels.
* An HDTV wide-screen (16:9) image will resize to fill the screen horizontally
in a 16:9 aspect ratio (i.e., with top and bottom borders).

 WHEN “CUSTOM” APPEARS: The “Custom” descriptor appears in the automati-
cally when any of the values for Size, Vertical Stretch, H-Position, V-Position or
Blanking do not correspond to those for a preset. It should not appear as an option in
your Resize Presets pull-down list.

 SELECT “NO RESIZING” to display the image in its native resolution, which may
be small or larger than 1280 x 1024. All Size, Vertical Stretch, H-Position, V-Position or
Blanking values will change accordingly. For example, for a source with a native resolu­tion of 800 x 600, “No Resizing” will center a small image within a black border.
Conversely, an HDTV image is wider than 1280 and will be cropped on the sides or, in
the case of “1080i” HDTV, cropped at top and bottom too.

 SELECT “FULL SCREEN” (default) to center and display your image as large as
possible for the present source. Note that video and HDTV both maintain their original
aspect ratios (i.e., there will be at least a few unused pixels), other sources change their
aspect ratios as necessary

OPERATION

order to fill the screen. Non-HDTV (16:9) anamorphic images, common on DVDs, will be
stretched vertically. With the exception of HDTV (16:9), the “Full Screen” setting produces an
aspect ratio that is either almost or exactly 4:3.

 SELECT “ANAMORPHIC” to display an entire
non-HDTV “wide screen” (anamorphic) image in its
native 16:9 aspect ratio. The image will fill the
screen from left-to-right, but will not use all vertical
pixels available (top and bottom will be black). If
you do not choose “Anamorphic” when a non-HDTV
anamorphic image is present, the default image will be stretched vertically, characterized
by obvious distortion and “thin people”.

NOTE: Use “Anamorphic” for regaining a 16:9 display of non-HDTV anamorphic
sources only (typically found on some DVDs, for example). For HDTV, the “Full
Screen” default will produce the same result.

Size

Size controls both the image width and height in tandem, maintaining the original aspect ratio
(proportion) of data from the incoming signal. 1000 = no resizing.

Vertical Stretch

Vertical stretch adjusts the height the image while keeping the width constant. Use Vertical
Stretch to display data from the incoming signal in a different aspect ratio. 1000 = no vertical
stretch (i.e., native aspect ratio).

Pixel Track

(SHORT CUT: Press and adjust the top slidebar.)
Pixel tracking adjusts the frequency of the pixel sampling clock, indicated by the number of
pixels per line, so that all pixels generated by a particular source are sampled. Proper pixel
tracking ensures that the image quality-whether good or poor- is consistent across the screen,
and that pixel phase can be optimized (below).

NOTE: By default, the projector will sample at the correct frequency for most sources.

Pixel tracking is adjusted most effectively using a good test pattern, such as a smooth gray con­sisting of a clear pattern of tiny black and white dots, or a similar “half on, half off” graphic
image, such as the Windows shutdown screen. Steady flickering or several soft vertical stripes
or bands across the entire image indicates poor pixel tracking. Adjust the slidebar until the
stripes broaden to the point where one large stripe fills the image. Again, the image may still
exhibit some noise. See Pixel Phase.

OPERATION

Pixel Phase

(SHORT CUT: Press and adjust the bottom slidebar.)

Pixel phase adjusts the phase of the pixel sampling clock relative to the incoming signal. It is
used primarily for adjusting RGB inputs.

NOTE: Adjust pixel phase after pixel tracking is properly set.

Adjust pixel phase when the image (usually from an RGB source) shows shimmer or “noise”.
Pixel phase adjustment is done most effectively from within a proper test pattern, such as a
smooth gray consisting of a clear pattern of tiny black and white dots, or a similar graphic
image, such as the Display mate program. Adjust until the image is stable and each dot is clear­ly defined. Using the numbers on the slidebar as a guide, you will notice that you can actually
stabilize the image at more than one point-i.e., you may find that the image appearance at “11”
is identical to the image appearance at “38”, thus you can select either setting.

Filter

Filter applies a low pass filter to the input signal. This removes high frequencies which can
improve pixel phase noise but which also reduces signal bandwidth. Note that most signals will
not require any filter adjustment-use the filter option only if standard pixel tracking and phase
adjustments do not adequately clear up a “noisy” signal. For best results:

1. Optimize Pixel Tracking and jot down the value.

2. Optimize Pixel Phase

3. If the image is still too noisy, return to Pixel Tracking
and “mis-adjust” so that 2 vertical bands of noise appear,
separated by a good center band. See right.

4. Adjust Filter to maximize the width of the good area. See
right.

5. Return Pixel Tracking to its correct setting from Step 1.

6. Readjust Phase.

NOTE: “Filter” affects only the current signal.

H-Position

Blanking: Top, Bottom, Left or Right

This submenu blanks (turns to black) the top, bottom, left, or
right edge of the image so that any unwanted information is
cropped from view. For example, when displaying native size
video you may want to blank out a few of the top lines.

Image Settings

Use any of the following slidebars, pull-down lists or the checkbox to alter your image. Refer
to "Using Slidebars and Other Controls" (earlier in this section) if you need help in selecting
options and adjustments. Changes made to the Image Settings menu are applied immediately
and are saved when you exit the menu (press or ).

Figure 3.13. Image Settings Menu

Contrast
(SHORT CUT: Press and adjust the slidebar.)

"Contrast" increases or decreases the perceived difference between light and dark areas of your
image (0-100). If contrast is set too high, the light parts of the image lose detail and clarity. If
set too low, the light areas will not be as bright as they could be and it may be difficult to dis­tinguish between foreground and background information. Adjust so that whites remain bright
but not distorted or tinted. For best results, keep close to 50.

NOTE: If environment lighting changes, it may be necessary to re-adjust both options.

Brightness

(SHORT CUT: Press and adjust the slidebar.)

"Brightness" increases or decreases the amount of perceived light in the dark part of the image
(0-100). If video or data is displayed with a black background, adjust until the background just
changes from black to very dark gray. For best results, keep close to 50.

OPERATION

Color

(SHORT CUT: Press and adjust the slidebar.)
“Color” adjusts color saturation level, or the amount of color in a video image. For example,
setting Color to “0” produces a black and white image. If Color is set too high, the color levels
in the picture will be over-powering and unrealistic. Use or until the desired color
saturation level is displayed. NOTE: COLOR is not available in the RGB mode.

Tint

(SHORT CUT: Press and adjust the slidebar.)
“Tint” adjusts color hue to obtain true color reproduction of NTSC video signals. Use or

until you reach optimum balance of red-to-green in your image. It is best to adjust tint
while displaying a proper SMPTE color bar test pattern-otherwise, it is recommended that tint
remain at its default setting. NOTE: TINT is not available in the RGB mode.

Detail

(SHORT CUT: Press and adjust the slidebar.)
“Detail” adjusts the sharpness of the video image. Use or until the display is as
sharp as possible, keeping in mind that any level of detail above 3 (default) will increase the
level of detail as well as introduce some level of noise in the image. Set below 3 to filter the
signal and remove noise from a noisy source. Keep at 3 to apply no detail. NOTE: DETAIL is

not available in the RGB mode.

Color Temp

“Color Temp” applies either a preset color temperature (3200K, 5400K, 6500K, 9300K) or any
previously defined Interpolated or custom “User” color temperature. All temperatures are meas­ured in degrees Kelvin and represent the “coloration” (reddish or bluish) of the whites dis­played by the projector-the lower the temperature, the more reddish the whites, the higher the
temperature, the more bluish the whites.

NOTE: Custom temperatures (“User” or “Interpolated”) can be defined in
the Advanced Color Temperature menu-until then, these choices all default to
6500K. See Section 3.8, Adjusting System Parameters and Advanced
Controls.

Color Space

This option determines how the color components of an input signal are decoded for accurate
color in the display. Selecting a color space option is useful only for analog signals connected
to INPUT 1 or INPUT 2. Although the color space for such a signal is automatically deter-
mined by the projector, in some circumstances you may wish to override this and manually set
a different color space.

NOTE: For digital signals or for signals connected to INPUT 3 or INPUT 4, the color space
function is entirely automatic and the pull-down list disabled.

 Select YPbPr (HDTV) if you are using a high definition decoder (HDTV).

Video Standard

The projector automatically detects the video standard present and displays the name of this
standard here. Press to view or select a different video standard from a complete list avail­able to the projector (some will appear disabled, depending on the current incoming signal).
Selecting a specific standard forces the projector to process the signal according to this stan­dard.

NOTE: This option should remain set at “Auto” for all instances EXCEPT: 1) a poor quality
input signal or 2) a black-and-white video signal. In order to detect and display such signals,
specify the relevant standard.

Gamma

NOTE: Gamma does not normally require adjustment and is intended for experienced users
only.

The “Gamma” option affects the shape of the gamma curve representing the levels and types of
grays available between minimum input (black) and maximum (white). Generally the best
gamma curve is one that produces maximum contrast, brightness and color performance. See
Figure 3.14.

THE 1.0 SETTING greatly reduces apparent contrast of mid-range signals and represents a
straight transition from black to white.

THE DEFAULT SETTING OF 2.2 is a normal and smooth gamma curve recommended for
virtually all sources, producing good contrast and smooth gray transitions without distorting
colors.

SETTING OF 2.2S OR 2.8S are not true gamma curves but are slightly S-shaped, resulting in
more intense mid-grays. If you use an “S” option, mid-levels in your display will be brighter
(they have more intensity) without whites crushing, however this abnormal grayscale will also
likely disturb color accuracy. Likewise, the 2.2SN curve is also distorted, but can improve some
NTSC signals.

THE 2.8 SETTING offers more apparent contrast of mid-range signals with fewer grays, and
may appear darker than the 2.2 setting. This is the official standard for PAL and SECAM sig­nals but it is almost never used for real signals which use 2.2.

3.7 Adjusting System Parameters and Advanced Controls

Use the Communications, Preferences and Status menus to display and/or alter overall system
parameters rather than those that affect a specific source or channel.
Use the Advanced menu whenever you need to work with or replace the lamp, select a test pat­tern, define a new color temperature, or access lesser-used image control settings intended for
experienced users.

Communications

Use the checkboxes and pull-down lists in the Communications menu to alter the methods or
types of communication to and from the projector. Refer to “Using Slidebars and Other

Controls” subsection if you need help. Changes made to the
Communications menu will be saved when you exit the menu.

Baud Rate

The baud rate setting determines the speed of communications to and from the projector. By
default, the projector baud rate is set to 9600. Setting the correct speed is important when you
are controlling the projector with an external device or another projector via an RS-232 or
RS-422 port. You must set the projector baud rate at these ports to match the baud rate of the

controlling device. If you are unsure about what baud rate to choose, refer to the
documentation for the controlling device.

NOTE: 1) The baud rate setting does not affect the switcher port, which is always 9600 baud.

2) See 2.9, Serial Port Connections and Appendix D for more information about cable connec-

tions between devices.

OPERATION

Front IR / Back IR

As described in Section 2, the standard IR remote keypad is capable of sending data to the pro­jector in either one of two protocols called A or B. Likewise, the front and rear IR sensors on

the projector can be set to accept IR data accordingly, responding to A, B or
both. The projector’s A or B default is adequate for most single-projector
installations. Select a specific protocol to prevent interference when you are
controlling two protectors in the same area and want to work with one projec­tor at a time.

Note that the front and rear IR sensors cannot respond to different protocols-if you change a
protocol for either sensor to anything other than OFF, the protocol for the other sensor also
changes. For example, setting Front IR to B also changes the Back IR to B. If you want only
one sensor to respond to a particular protocol-A, B, or A or B-disable the other sensor by set-
ting its protocol to OFF.

If you want to disable both IR sensors, you cannot use the IR remote keypad to select the sec­ond OFF setting. This safeguard prevents accidentally disabling a keypad while you are using
it. Instead, use either the built-in keypad or the wired remote to set the remaining active sensor
to OFF. The projector will no longer respond to an IR remote keypad.

IMPORTANT

Keep at “A OR B” unless you are sure of

the current IR keypad protocol.

NOTES: 1) The IR remote keypad for this projector is set at Runco to “Protocol A”. See 2.10,
Keypad Protocols and Conversion for information about changing the keypad protocol. 2) A

key press from a conflicting protocol will cause a single yellow flash on the Status LED located
in the lower right corner of the rear projector panel.

Wired Keypad

Like the IR remote keypad, the optional wired keypad is either a “Protocol A” keypad (default)
or a “Protocol B” keypad. Likewise, the projector can be set to accept wired keypad data
accordingly, responding to A or B. If desired, you can prohibit the projector from responding to
a particular wired keypad protocol, or you can ensure that the projector responds to either pro­tocol (default). You can also prevent the projector from responding to the keypad entirely. In
the pull-down list, select the desired protocol.

NOTE: The wired keypad for this projector is set at manufacture to “Protocol A”. See 2.10,
Keypad Protocols and Conversion for information about changing the keypad protocol.

ADDING A PROTOCOL: To add a protocol, select the A or B option.

CHANGING A PROTOCOL: As a safeguard, you cannot accidentally select an option in the

“Wired Keypad” list that would disable the wired keypad during use, since such options are
automatically disabled in the list. In other words, you cannot switch to the opposite protocol or
select OFF using the wired keypad. Instead, if you want to quickly change to the other protocol,
you may find it more convenient to use one of the other keypads (the built-in keypad or the IR
remote) to execute the protocol change for the wired keypad. The projector will now recognize
only the opposing change for the wired keypad protocol. Or, if you prefer, use the wired keypad

1. A or B

2. A

3. B

4. Off

3-28

OPERATION

to safely change its own protocol:

1. Select the A or B option. This will ensure that once your keypad is manually changed
(see Step 2), it will still be recognized by the projector.

2. Unplug the keypad and change the protocol in the keypad as desired. Do this either
by entering the short-cut software command or by hard-wiring the keypad as
described in 2.10, Keypad Protocols and Conversion.

3. Plug the keypad back into the projector. Return to the Communications menu and
select the new protocol you have just set up in the wired keypad.

TURNING OFF THE WIRED KEYPAD: If you want to disable the wired keypad entirely,
you cannot use it to select the OFF option. This safeguard prevents you from accidentally dis­abling the wired keypad during use. Instead, use either the built-in keypad or the IR remote
keypad to select OFF. The projector will no longer respond to the wired keypad.

Broadcast Keys

Enter a checkmark if you want keypad commands sent to one projector to be relayed to all pro­jectors in a network. Note the key will temporarily “override” the effect of a broadcast
setting and allow you to control a specific projector when necessary.

Projector

Enter a three-digit number (such as “001”) to assign or change a number to the projector cur-

rently in use-if the current projector already has a number
assigned, that number will appear here. Numerical identity
for projectors is required whenever you want to communi­cate with a single projector within a multiple-projector
application (see key description in 3.8, Using the
Keypad). If you make a mistake in assigning or changing
the projector number, press to cancel.
For complete information about controlling multiple pro­jectors, see Section 3.8.

Preferences

Use Preferences checkboxes and pull-down lists to alter how the projector responds to com­mands and displays its parameters. Refer to the “Using Slidebars and Other Controls” subsec­tion if you need help. Changes made to the Preferences menu will be saved when you exit the

NOTE: The Channel List and input dialog box cannot be hidden when a menu is displayed.

Display Slidebars

Enter a checkmark to superimpose a small slidebar over the current image when an adjustable
parameter is selected directly with a key (the option does not affect slidebars in menus). These
“direct” slidebars include volume, contrast, brightness, position, pixel tracking and phase, and
others. If “Display Slidebars” is unchecked, these slidebars will be hidden during adjustment.

Display Error Messages

Choose in what way you want to be notified of errors detected in either the incoming signal or
projector. Select “Screen” or “All” if you want a brief message displayed. If you prefer to be
notified via a serial communication only (RS-232 or RS-422), select “RS232” instead. To dis­able error messages entirely (except invalid user entries), select “Off”.

NOTE: Display of invalid user entries cannot be disabled, even if you choose the “Off” option.

Auto Power Up

Enter a checkmark to enable the projector to automatically power up after losing power due to
unplugging or a power failure. Note that unsaved display adjustments may be lost.

Video Termination

Enter a checkmark to terminate the video inputs 3 and 4 (75 W). The input should be terminat-

ed unless the signal loops through (continues) to another
projector or display device, in which case only the last
projector in the chain should be terminated.

Menu Options

In this submenu, choose the default location desired for on-screen menus. You can use the shift
options to move a location up or down, creating a Custom location. Note that menus for this
projector often expand and can be quite large-avoid placing them too low or too far to the right
where they may be cropped.

Advanced Controls

The Advanced menu includes a variety of special options
that an experienced operator may want to adjust for certain
applications, such as color-critical displays or multiple
projector walls. In addition, this menu provides access to
test patterns, lamp settings and service, and the password­protected Service submenu.

TEST PATTERNS - Select this option to use a pull-down list of all avail-

able internal test patterns.

NOTE: For quicker access from your presentation, use the key to
cycle through the patterns. At the last pattern, press to return to your
presentation-or press at any time.

FREEZE IMAGE - Use the “Freeze Image” checkbox to freeze (stop) the
image at a single frame. This diagnostic tool is useful if you need to exam­ine in detail a still version of the incoming image that may not be “freez­able” at the source. For example, in moving images it is difficult to observe artifacts such as
external deinterlacing/resizing and signal noise.

COLOR ENABLE - Select which color or colors you want to see, useful while working with
color temperature white levels or input levels.

Input Levels

NOTES: 1) It is recommended that only experienced users use the Input Levels menu-the pro­jector automatically optimizes input levels for all but the most unusual of sources. 2) Always
check that overall contrast and brightness settings are near 50 and that color temperature is
properly set up on an internal grayscale test pattern before attempting an input level adjust­ment. 3) There must be at least one white pixel present in the image for “Auto” to work.

Good RGB or input levels-that is,
the drives and blacklevels for each
of the three colors, red, green and
blue-ensure that images from analog
sources other than decoded video
have maximum contrast without
crushing black or white. By default
(and in an “Auto Setup” from the
Main menu), the projector automati­cally determines the best input levels
by monitoring image content and
adjusting the controls appropriately-further adjustment is typically not required to obtain proper
blacks or whites. NOTE: This automatic adjustment requires at least 1 white pixel in the image.

Without a white pixel, input levels may produce skewed colors, particularly in non-video
images.

However, for a very unusual source an experienced user may prefer to use the Input Levels
menu (see Figure 3.19). This adjustment, which is actually a calibration process to compensate
for differences in sources and cabling, enables an experienced user to perfect the source image
input levels.

AUTO INPUT LEVEL - Keep off for virtually all sources (default). Temporarily enter a
checkmark only if you are an experienced user and you have an unusual source that you feel
needs further color temperature and/or input level adjustment. After entering a checkmark, wait
for the six values to stabilize, then delete the checkmark.

OPERATION

BLACKLEVELS AND DRIVES - To check your image and adjust these controls:

1. Make sure overall Contrast and Brightness are both set to near 50. NOTE: Not

required for “Auto” adjustment.

 = 50 (approx.)
 = 50 (approx.)

2. Check the color temperature setup using an internal grayscale test pattern, adjusting

as desired to obtain a neutral grayscale. NOTE: Not required for “Auto” adjustment.

3. Make sure you are using an analog source not connected to INPUT 3 or INPUT 4, as

Input Levels are not applicable for digital sources or sources going through the decoder.
A grayscale is recommended.

4. If the blacks and/or whites appear OK, input levels do not need adjustment. If the

image has poor blacks and/or white, continue with Step 5.

5. Temporarily enable “Auto” in the Input Levels submenu. Wait for all 6 values to sta-

bilize.

6. Delete the “Auto” checkmark and leave the Input Levels menu.

To adjust black levels and drives manually, judge by eye and change one or more of the six lev­els as necessary to obtain proper blacks and whites. You may want to see only a certain color
while adjusting-use the “Color Enable” option (described below).

CLAMP TIP - This option (full name sync tip clamping) can brighten the image produced
from certain high resolution, high frequency graphic sources. Enter a checkmark if the image
appears unusually dim, if there are horizontal streaks across the image, or if there is significant
color drift. Delete the checkmark if the image is either sufficiently bright or overly bright.

NOTE: The sync tip clamping option is not used for video sources or any RGB source with sync
information on the video (e.g., sync-on-green).

COLOR ENABLE - Select which color or colors you want to see, useful while working with
color temperature white levels or input levels.

NOTES: 1) Input levels apply for the current source only, but for any color temperature used.

2) Assuming that color temperature has been set up based on the internal test patterns, you can

then set up input levels for a given source so that it matches the color temperature of the inter­nal test patterns.

OPERATION

Odd Pixel Adjustment

NOTE: For sources with Color Space set to RGB only.

When using certain RGB sources with static
images, you may need to adjust the normal gain
or offset of odd pixels in relation to even in
order to smooth out very narrow (1-pixel wide)
checks or vertical stripes. These patterns signify
adjacent “on” and “off” pixels, and can be
removed as follows:

1. Use an external grayscale test pattern of some kind (make sure it has both dark grays

and light grays).

2. Make sure the image is displayed in its native resolution, i.e. with No Resizing.

3. Display a single color - choose through the “Color Enable” menu option or use the

key shortcuts shown on the back of the remote keypad.

4. Examine an area of darkest gray (but not black). If there is a 1-pixel wide pattern

present, adjust “Odd Pixel Adjustment” offset for the current color. Stop when the pat­tern disappears and the area is smooth.

5. Examine an area of lightest gray (but not white). If there is a 1-pixel wide pattern

present, adjust “Odd Pixel Adjustment” gain for the current color. Stop when the pattern
disappears and the area is smooth.

6. Repeat for each color, adjusting offset then gain for each.

NOTES: 1) Always adjust offset before gain, since offset affects gain. 2) A value of 128 repre­sents no change in normal odd pixel offset or gain. 3) Odd Pixel Adjustment eliminates “1 pixel
on, 1 pixel off” patterns only, not any type of larger patterns.

Advanced Color Temperature

Select the Advanced “Color Temp” option if you want to apply, alter, add, or copy a color tem­perature, or if you want to use an unaltered factory default color temperature.

By default, the projector can utilize any of four calibrated factory-set color temperatures: 3200,
5400, 6500 or 9300 (expressed in degrees Kelvin). For most applications, these temperatures
will display accurate and realistic colors from a variety of sources. They can be selected at any
time in either the Image Settings menu or in the Advanced Color Temperature menu.

Func

3-34

OPERATION

However, if you require extra color temperatures, you can also add up to five custom color tem­peratures-four "User" and one "Interpolated"-by defining them within the Advanced Color
Temperature menu (each defaults to 6500K until then). Any "User" or "Interpolated" tempera­ture created here is immediately applied, or it can be selected at any time from the Image
Settings menu as usual, regardless of your source or channel. The Advanced Color Temperature
menu options are described below.

NOTE: For best results, use an internal grayscale test pattern when working with color temper­ature.

COLOR TEMP - See Figure 3.20. Upon opening the Advanced Color Temperature menu, the
current temperature appears as the top option. You can change to a different color temperature
here as desired, just as in the Image Settings menu. Note that if you select a "User" color tem­perature, the "White Level" options further down in the Advanced Color Temperature menu are
no longer disabled-you can adjust them as desired to define or change a "User" color tempera­ture (see "White Levels", below). Likewise, selecting "Interpolated" here activates the
"Interpolated" slidebar for defining or changing an interpolated color temperature.

INTERPOLATED - Select this option if you need a specific color temperature that lies some­where between one preset color temperature and another. Adjust the slidebar to define a new
temperature that will be interpolated from the neighboring presets (for example, 7841 is inter­polated from 6500 and 9300). It can be used any time and appears as a 4-digit temperature
when present.

WHITE LEVELS -These 3 controls are adjustable only if a "User" choice is selected (in
which case "User 1, 2, 3 or 4" appears at the top of the Advanced Color Temperature menu).
Their current values are shown for the active color temperature. Changing a white level here
changes the drive (contrast) for that color, essentially creating a new color temperature that is
"warmer" or "cooler" etc. When you are satisfied with the new "User" temperature, it can be
used immediately upon exit or it can be selected from either the Image Settings menu or the
Advanced Color Temperature menu as usual. You can re-define a "User" color temperature at
any time using the Advanced Color Temperature menu.

COLOR ENABLE - Select which color or colors you want to see, useful while working with
color temperature white levels.

Figure 3.20. Advanced Color Temperature Menu

OPERATION

COPY FROM - Use this option to replace the currently selected "User" color temperature

setup with that of another. This function can be particularly useful for creating a starting point
for a new "User" color or for accessing an unaltered factory default. It is disabled for all color
temperatures except "User". See Figure 3.21.

Figure 3.21. "Copy From"

To create a starting point: To set a starting point for a new custom user color temperature,
select a user temperature, then highlight "Copy From" and select a temperature that is similar to
what you want. Adjust white levels from there as desired.

To use a factory default: The preset color temperature setups (3200K, 5400K, 6500K and
9300K) can be altered from within the password-pro­tected Service menu only-note that although such an
alteration changes the setup and appearance for a pre­set, it does not change its name. If you suspect that
you are using a preset temperature that has been
altered and you want instead to use the original cali­brated factory color temperature without clearing the
entire projector memory, you can use the "Copy From"
option in the Advanced Color Temperature menu to set
up a "User" temperature with settings from a perma­nent factory preset:

1. Enter the "User" color temperature you wish to update at the top of the Advanced Color
Temperature menu, such as "User 2".

2. From the "Copy From" list, select the matching temperature labeled "Factory" (such as
"Factory 5400K").

3 The setups for the "User" color temperature you entered at the top of the Advanced Color

Temperature menu will now be updated/replaced by those for the permanent factory cali­brated temperature you selected in the "Copy From" list. Again, a "User" temperature can
be altered at any time, if desired.

OPERATION

Advanced Image Settings

DECODER LUMA DELAY - This option

affects any incoming composite or S-video sig­nal, delaying the luma signal (intensity) in rela­tion to the chroma (color). In the image,
increasing the luma delay will move luma (seen
as a shadow where colors overlap) to the right
slightly, with colors remaining in place.
Decreasing this delay will move the shadow slightly to the left. If necessary, adjust so that no
shadows occur with adjacent colors.

INPUT VIDEO BLACK - This option determines where black levels are determined in rela­tion to the clamping location on a video signal, so that blacks are neither crushed (i.e., with
dark gray appearing black) nor elevated (i.e., with black appearing dark gray). If black is
crushed in the current image, set to "0 IRE" so that blacks are at the clamping level. If black is
elevated, set to "7.5 IRE" so that blacks are set above the clamping level.

VCR - This option determines to what degree the projector tolerates signal disturbances. The
correct setting is automatically determined and set according to the type of incoming source
signal-for instance, there should be a checkmark for all VCR sources. The VCR option may
require a change from its auto setting in very rare circumstances only, such as if you are having
difficulty switching between two unusual and almost identical VGA computer sources.
Otherwise, it is not necessary to change this option.

MOTION FILTER - This option is most useful for smoothing out de-interlacing artifacts that
sometimes occur with moving interlaced images (such as HDTV). By default, the correct set­ting is automatically determined according to the type of incoming source signal. If desired,
override the default setting as follows:

1. Turn to OFF (delete the checkmark) if you have a static image.

2. Turn to ON (enter a checkmark) if your mov­ing image exhibits motion artifacts. The image will be
smoother while forfeiting some sharpness.

Lamp

Whenever you install a new lamp in the projector you need to
access the Lamp submenu and record the lamp serial number
in the projector's memory. You can also set different Lamp
submenu options such as intensity (output) or power required.
These setups can be changed at any time.

NOTE: See 4.4, Replacing the Lamp and Filter for complete
instructions on installing a new lamp in the projector.

From the Advanced menu, select the "Lamp" option for access to the Lamp submenu, where all
lamp functions and data appear. Read-only information includes the number of hours logged on
the lamp so far and the serial number recorded for the installed lamp.

Figure 3.23. Lamp Submenu

3-37

OPERATION

LAMP HOURS shows the number of hours logged on the current lamp. Whenever you record

a new lamp serial number, this value automatically resets to "0", where it begins to log time for
the new lamp. NOTE: Read-only. This information also appears in the Status menu.

LAMP S/N is the serial number recorded for the current lamp. When you install a new lamp
and enter its serial number, the number will appear here in the Lamp menu. NOTE: Read-only.

Enter a checkmark for LAMP MESSAGE if you want to enable a warning message upon
power-up that the lamp has reached the specified lamp limit and should be replaced. Delete the
checkmark if you do not want to see this warning-instead, when your lamp expires, only the
status information on the back of the projector will provide the warning to replace the lamp.

NOTES: 1) It is recommended that the Lamp Message checkbox remain enabled. 2) When a
lamp warning message appears, press to temporarily cancel the message. The message will
continue to appear upon power-up until you install a new lamp.

Set LAMP LIMIT to the number of hours you expect to log on the current lamp before replac-
ing it. The recommended limit is 1000 hours.

NOTE: 1) If you change modes over the life of a lamp, the lamp limit you originally expected
may no longer be possible. 2) Turning the lamp on and off reduces lamp life significantly, as do
other factors.

Set which LAMP MODE you want to use in order to control the light
output. Although there are exceptions, in most lamps, the higher the
light output or power setting, the shorter the life span of the lamp.

Use the lamp mode that best suits your brightness needs. For example, in
a tiled application you may want to precisely match brightness levels between adjacent images­choose Intensity for each projector, then judge by eye and set each individual intensity setting
as necessary (see "Intensity", below). Or you may simply always need as much brightness as
possible-choose Max Brightness.

Lamp modes are described below:

 Max Brightness: The lamp will always burn as brightly as possible, driven by maximum

power of 700W. Keep in mind that the "maximum brightness" for any lamp gradually
diminishes with age-the image will become dimmer over time. Its current output level
appears in the "Intensity" option (not in lumens).

 Intensity: Brightness will remain at a specified level for as long as possible. Once you

select this option, enter a number representing the intensity level (brightness) you wish to
maintain. Note this value is a correlation only (0-9999), not actual lumen levels possible
(0-3000, e.g.). See "Intensity" below.

 Power: The power supplied to the lamp will remain at a desired watt level throughout the

life of the lamp. Once you select this option, enter the number of watts representing the

Figure 3.24

3-38

OPERATION

power level you wish to maintain. See "Power" below.

POWER - The number shown here indicates how many watts are applied to the lamp. Set from

450-700 watts as desired, keeping in mind that lower power levels produce dimmer images.
When in "Power" or Max Brightness modes, the power level remains constant. When in
"Intensity" mode, the power level will change as necessary. Specifying a power level of 700 is
the same as operating in Max Brightness mode.

NOTES: 1) Power level can be set only if the lamp is in "power" mode. 2) If you are in
"Intensity" mode, the power level value will automatically increase over time as necessary to
maintain the desired brightness, until power reaches 700W.

INTENSITY - This number is a representation of the current brightness of your lamp, decreas­ing over time when you are operating at Max Brightness or at a specific Power level.
However, when you are operating in "Intensity" mode, this value remains at the original
"Intensity" setting chosen.

NOTE: The number shown for "intensity" is not the actual lumen output, but rather a correlat­ed value only-9999 may represent 3000 lumens, for example.

To use "Intensity" mode, judge by eye and set the level as desired for your application, remem­bering that higher settings can significantly shorten lamp life. Over time, the projector will
automatically increase the power supplied to the lamp as needed to maintain the chosen intensi­ty to within 5% of the setting. This is called "brightness tracking".

Keep in mind that once the lamp power has reached its maximum of 700 watts (see "Power",
above), this tracking is no longer possible. At this point, the lamp will gradually begin to dim as
usual, even though your original "Intensity" value will still appear in the menu. To resume
accurate tracking, reduce the intensity setting so that the resulting "Power" value is under 700
watts - the lower the intensity, the longer it can be maintained.

Do not lower the "Intensity" so much that the corresponding "Power" value reaches its mini­mum of 450 watts - the intensity setting will be inaccurate and cannot be maintained. For
matching intensity over in tiled images, choose an intensity setting that enables all lamps to
operate at less than 700 watts.

NOTES: 1) Lamps become more stable over time, thus a specific intensity is more easily main­tained as the lamp ages 2) Intensity can be set only if the lamp is in "Intensity" mode 3)
Intensity cannot exceed the output of Max Brightness mode.

LAMP HISTORY - This read-only option lists the most lamps most recently
installed and recorded in the projector. Lamp History automatically updates
whenever you record a new lamp serial number-the new lamp is added to the
bottom of the list.

3.8 Using Multiple Projectors

When working with multiple projectors, you may want to use the RS-232 or RS-422 serial ports
to chain the projectors together in a network that you control from either a keypad or a comput­er/controller (see 2.9, Serial Port Connections). Or you may prefer that each projector stands
alone, in which case you will probably use a single IR remote keypad. In either case, you can
switch back and forth between broadcasting to all projectors or controlling each projector indi­vidually.

Assigning a "Projector#"

Make sure you have assigned a unique projector number to each projector present - this number
will be required in order get the exclusive attention of an individual projector. To assign a pro­jector number:
Press and select the Communications menu. In the Communications menu, scroll down to
"Projector#" and enter a three-digit number (000 to 999) for identifying the current projector.
Press to accept the entry, or to cancel.
Repeat for each projector, using a unique three-digit number for each. Once every projector has
its own number, you can begin to control the network.

Controlling One Projector

If you are using an IR remote, press to display an editable window. Enter the three-digit
number you have assigned to the projector you wish to control. All keypad commands will then
affect this projector exclusively until you press again and enter a different number, or until
you switch to broadcast mode (below).
If you are using a wired remote keypad (optional) in a network of projectors, make sure that the
projector to which the keypad is connected has its "Broadcast Keys" option checked. Press to
bring up the editable box. Enter the three-digit number assigned to the projector you want to
control - keypad commands will now affect only the desired projector until you press
again and enter a different number, or until you switch to broadcast mode (below).

NOTES: 1) If you are using a computer or controller to issue commands, use the correct RS­232 software command to gain control of a single projector.

Broadcasting to All Projectors

On the IR remote or wired keypad, press to display the projector box. Press again without
entering a number - the keypad commands will now affect all projectors.

Make certain that only one projector has its "Broadcast Keys" option selected (checked) - the
remaining projectors should have the option unchecked and their keypads disabled (do this in
Preferences menu). The "Broadcast Keys" projector will then relay keypad commands to the
others. If using a wired remote, make sure to select the "Broadcast Keys" option for the projec­tor to which the wired remote is connected.

NOTE: If you are using a computer or controller to issue commands, use the correct RS-232
software command to broadcast.

3.9 Error Conditions

Occasionally the projector may encounter an error condition that interrupts normal operation.
Such a condition can be caused by an invalid user entry, an input signal error (most common)
or other system error.

If you would like to be notified on-screen of such errors, select the "Screen" option from the
"Display Error Messages" pull-down list (in Preferences menu). If you would like to be notified
via a serial communication only, select the "RS-232" option instead. To receive both notifica­tions, select "All". To disable error messages (except for invalid user entries), select "Off".

NOTE: Error messages also always appear at the rear LCD next to the keypad.

User Errors  Invalid User Entry

Any keypad entry not recognized by the projector will trigger an on-screen error message
describing the problem. For example, if you specify a channel number that has not been
defined, the message "Invalid Channel” will appear. Or if you try to enter the wrong password,
you'll see "Invalid Password". Press or to confirm the message and eliminate the
message box.

NOTE: Displaying of "Invalid User Entry" messages cannot be disabled, even if Display Error
Messages has been set to "Off".

Input Signal Errors

Input signal errors messages appear when there are no menus present, and have selected an
input on which the projector detects a problem. While menus remain operational and pressing
any key will temporarily remove the message from the screen, you must resolve the signal
problem in order to permanently eliminate the message.

NOTE: Input signal messages appear on-screen only if Display Error Messages has been set to
"Screen" or "All".

No Signal

The message "No signal" appears when there is no signal detected at the selected input. Both
HSYNC and VSYNC are inactive and the screen background is black. Connect or correct the
signal, or select another input.

Enter

Exit

3-42

OPERATION

Bad Sync

The message "Bad Sync" is displayed when HSYNC or VSYNC are active but the signal can­not be displayed. Such a condition occurs when only one of the two signals is present, or when
either signal is unstable or of the wrong frequency. Correct the signal or select another input.

Other Signal Error Messages

In addition to the common "Bad Sync" and "No Signal" errors, you may encounter a signal
error message indicating that Hsync and/or Vsync are either too fast or too slow. When such a
message appears, check the frequencies shown in the Status menu. If they are correct, then the
signal may be out of the projector's operating range. On some PCs you may be able to change
the settings to generate a compatible signal. If the frequencies shown in the Status menu are
incorrect, check the cabling to see where the problem is.

System Warnings / Errors 

When the projector encounters a system malfunction, either a System Warning message or a
System Error message may appear. Both types of messages are accompanied by a steady red
"Power" LED and a flashing red-and-yellow error code on the "Status" LED. This condition
indicates the need for service by a qualified Runco service technician.

NOTE: System messages appear on-screen only if Display Error Messages has been set to
"Screen" or "All".

System Warnings

A system warning message indicates that a system malfunction has been detected (see Status
LED Codes, below). A system warning message replaces any input signal message and disap-

pears when the input signal status changes. While the projector will remain operational, the
message indicates the presence of a serious problem that should be reported to the manufactur­er. You can press to remove the message, but for best results you should reset the projec­tor-power the projector down and up again with the key.

System Errors

A system error message indicates that a serious malfunction has been detected and must be
reported to the manufacturer (see Status LED Codes, below). The projector will no longer oper­ate and must be reset-power the projector down and up again with the key.

The Status LED Codes

If the "Status" LED on the back of the projector repeatedly flashes a pattern of yellow and red
light while the "Power" LED glows a continuous red, you have encountered a likely system
error requiring the attention of a qualified service technician (see System Warnings and System
Errors, above). Try resetting the projector by powering it off and on again, cooling when neces­sary. Consult Table 1 and contact your Runco dealer if the problem persists.
The specific pattern of flashing indicates the 2-digit code identifying the type of problem
encountered-the number of yellow flashes represents the first digit and the number of red flash­es indicates the second digit. For example, a pattern of "yellow-yellow-red-red-red" is "Code
23", meaning the lamp ballast (power supply) is overheated. These codes include:

Maintenance

4.1 Warnings and Guidelines

This projector is CSA approved and is designed for safe and reliable operation. However, safe
operation cannot be assured by design alone; installers, maintainers, and users must maintain a
safe operating environment for the system. Please read through and understand the following
warnings and guidelines promoting safe usage of the projector.

WARNING

Never look directly into the projector lens.

The extremely high brightness of this projector

can cause permanent eye damage.

WARNING

For protection from ultraviolet radiation,

keep all projector shielding intact during operation.

Labels and Markings 

Observe and follow all warnings and instructions marked on the projector.

The exclamation point within the equilateral triangle alerts the user to important
operating and maintenance (servicing) instructions in the literature accompanying
the projector.

The lightning flash and arrowhead symbol within the equilateral triangle alerts the
user to non-insulated "dangerous voltage" within the projector's enclosure that may
be of sufficient magnitude to constitute a risk of electric shock.

Projector Location

Operate the projector in an environment that meets the operating range specifications in Section
5, Specifications. Do not operate the projector close to water, such as near a swimming pool.

Do not place the projector on an unstable cart, stand or table. If the projector is to be ceiling
mounted, only use a Runco-approved ceiling mount fixture.

A projector and cart combination should be used with care. Sudden stops, excessive
force, and uneven surfaces may cause the projector and cart combination to over­turn.

MAINTENANCE

Lamp and Filter Replacement

LAMP: Do not operate the Xenon lamp for more than 1000 hours; risk of the lamp shattering

increases as a result of changes in the quartz glass. Also, operation beyond 1000 hours signifi­cantly reduces brightness output.

WARNING

Never attempt to remove the lamp housing directly after use.

The lamp is under great pressure when hot and may explode,

causing personal injury and/or property damage.

Allow to cool completely.

The arc lamp operates at a very high temperature and pressure. Failure to
allow the lamp to sufficiently cool prior to handling could result in an
explosion causing personal injury and/or property damage. After turning
the projector off it is important that you wait at least five minutes before
unplugging it. This provides enough time for the internal lamp cooling
fans to cool the lamp and to automatically shut off. Cool completely
before handling.

WARNING

Use only lamps supplied by Runco.

FILTER: Replace the side filter every 1000 hours or sooner. If this filter is not replaced, air

flow may become restricted and cause the projector to overheat.

See 4.4, Replacing the Lamp and Filter for the complete replacement procedure.

WARNING

Use only filters supplied by Runco.

Power Cord and Attachments 

Only use attachments or accessories recommended by Runco, such as the 13 amp high-current
rated power cord supplied. Use of other attachments or accessories with this projector may
result in the risk of fire, shock or personal injury.

WARNING

Use only the AC power cord supplied.

Do not attempt operation if the AC supply and

cord are not within the specified voltage and power range.

Do not allow anything to rest on the power cord. Locate the projector where the cord cannot be
damaged by persons walking on it or objects rolling over it.

Operate the projector at the specified voltage only. Do not overload power outlets and extension
cords as this can result in fire or shock hazards. Runco recommends a dedicated AC circuit for
the projector itself.

!!!!!

4-3

MAINTENANCE

The projector is equipped with a three wire plug having a third (grounding) prong. This is a
safety feature. If you are unable to insert the plug into the outlet, contact an electrician to have
the outlet replaced. Do not defeat the safety purpose of the grounding-type plug.

Ventilation

Before unplugging the power cord, make sure the internal lamp cooling fans have shut off. The
fans automatically shut off when the projector has adequately cooled down.

Slots and openings in the projector provide ventilation. To ensure reliable operation of the pro­jector and to prevent overheating, these openings must never be blocked or covered. The pro­jector should never be placed near or over a radiator or heat register. The projector should not
be placed in an enclosure unless proper ventilation is provided.

Do not push objects of any kind into the projector through the ventilation openings. They may
touch dangerous voltages or short-out components resulting in a fire or shock hazard. Do not
spill liquids of any kind into the projector. Should an accidental spill occur, immediately unplug
the projector and have it serviced by a qualified Runco service technician.

Servicing

If any of the following conditions exist, unplug the projector from the power outlet and refer
service to qualified Runco service personnel.

 The power cord has been damaged.
 The internal cooling fans do not come on when the projector is first turned on.
 Liquid has been spilled into the projector.
 The projector has been exposed to excessive moisture.
 The projector does not operate normally.
 The projector has been dropped or the case has been damaged.

Do not attempt to service the projector yourself. All servicing must be performed by a qualified
Runco service technician. If replacement parts are required, it is important that only Runco­approved parts are used. Other parts may result in fire, electric shock or risk of personal injury.

4.2 Cleaning

Clean the projector when required. Before cleaning, always unplug the projector from the
power outlet.

Lens

To avoid the risk of scratching the lens, clean the lens only if absolutely required. A small
amount of dust on the lens will have very little effect on picture quality. If the lens must be
cleaned, use a DRY soft cotton cloth. Clean gently in a circular motion.

Lamp

It is important to never touch the glass surface of the lamp, as the oil imprint will seriously
degrade lamp performance. Should you accidentally touch the surface of the lamp, clean care­fully with a lint-free cloth moistened with isopropyl alcohol.

4-4

MAINTENANCE

Case

Clean the case with a soft dampened cloth. Use a mild commercial cleaner. Do not use liquid or
aerosol cleaners.

Figure 4.1. Replacing Keypad Batteries

4.3 Replacing Keypad Batteries

The optional IR Remote Keypad uses four AA size, 1.5V batteries (preferably alkaline). To
install new batteries, open the battery compartment at the back side of the keypad by pulling on
the raised portion of the cover as shown (Figure 4.1).

Remove the old batteries and properly discard. Wait a minute or two and place the new batter­ies in the compartment, orienting the positive/negative of each battery according to the labels in
the compartment. When batteries are in place, replace the cover by inserting its bottom edge
first and snapping the top into place. Do not force.

NOTE: Always wait a minute or two when replacing batteries so that the internal electronics
discharge and can recognize the change.

NOTE: For this procedure you will need a VX-5c Lamp and Filter Replacement Kit from
Runco.

The high brightness of your projector is provided by a 700 watt Xenon lamp permanently
mounted inside its own protective housing. When the bulb approaches 1000 hours of usage, this
lamp assembly should be replaced.

How Old is The Lamp?

The number of hours logged on the current lamp appears both in the Lamp submenu (accessed
through the Advanced menu) and the Status menu. In the Status menu, do not confuse “Lamp
Hours” with “Lamp Counter”, which indicates the number of hours logged during the ‘rental
period’, in a situation where the VX-5c is to be rented for various functions. In a permanent
install, this would be of no consequence.

NOTE: As the lamp nears its limit (as set in Lamp Limit), a message can appear on screen to
warn that the lamp needs to be replaced. To make sure that this warning appears, enter a
checkmark in the Lamp Message checkbox located in the Lamp submenu.

MAINTENANCE

4.4 Replacing The Lens

A variety of lenses are available to accommodate different throw distances and specific types of
installations. See page 5-1 for details. To change a lens, follow the steps below.

NOTES: 1) You will need a 9/64”(3mm or 3.5mm) hex socket ball driver (supplied with projec­tor) or allen wrench for this procedure. 2) “Top” or “bottom” references assume a non-invert­ed projector, as illustrated. 3) If you are installing a lens, first make sure its Lens Adapter is
present on either the lens or projector. Such an adapter/flange secures to the projector in the
same manner as the flange described below, but accommodates a screw-mount lens.

STEP 1 Turn off the projector, cool, and unplug.

Before removing or installing a lens, turn off the projector and allow it to cool for five minutes
before unplugging. Make sure that the lens cap is on.

WARNING

Unplug the projector.

Install the lens cap.

STEP 2 Loosen the 3 lens mount screws

 IF FIXED LENS: Use the hex socket ball driver
provided with the projector to loosen the 3 lens
mount screws that secure the lens flange to the
mount-loosen these screws only, do not remove. See
Figure 4.10.

Figure 4.9. Install lens cap

MAINTENANCE

IF ZOOM LENS: Access to the 3 lens mount
screws is likely blocked by the toothed zoom
ring in front of it. First rotate the zoom ring by
hand until its 3 access holes align with the
screws, then insert the hex socket ball driver
through the holes to loosen the screws-do not
remove. See Figure 4.11.

STEP 3 Rotate the lens barrel slightly

 Using both hands, rotate the lens barrel coun­terclockwise until the screw heads align with the
larger end of their slots on the lens. See Figure

4.12.

MAINTENANCE

STEP 4 Pull lens assembly out

 See Figure 4.13. Carefully pull the lens
assembly straight out of the projector and set
aside.

STEP 5 Install new lens assembly

 IMPORTANT: Remove the rear (smallest)
lens cap from the new lens. Make sure the front

lens cap remains on during installation.

 See Figure 4.14. Align the large cut-out area
on the lens flange to the bottom of the lens
mount (which has a matching cut-out). The 3
lens assembly slots should align with the lens
mount screws so that the screw heads will fit
through the large end of the slots.

NOTE: On most lenses, a small extra “keying”
slot located at approximately 2 o’clock on the
lens flange will align with a set screw in the
same location on the lens mount, preventing the
lens from being installed in the wrong orienta­tion. If the lens flange does not seem to fit into
place over all screws, try rotating the lens assembly in one direction or another.

MAINTENANCE

With the lens assembly aligned and the screws inserted through the flange, use both hands to
rotate the lens barrel clockwise until the lens mount screw heads lock into the small end of the
lens assembly slots.

Secure the 3 lens mount screws.

STEP 6 Reposition the projector for new lens

Remove the front lens cap and reposition the projector closer or further from the screen as nec­essary for the screen and the new lens type (refer to lens descriptions in Section 2 and Section 5
and Appendix E, Throw Distance). In a permanent installation, always use the appropriate throw
distance formula to calculate the distance accurately Power up and test. Adjust offsets as neces­sary.

4.5 Troubleshooting

If the projector appears not to be operating properly, note the symptoms present and use the fol­lowing guide to assist you. If you cannot resolve the problems yourself, contact your Runco
dealer for assistance.

NOTE: Always check the LCD status window at the rear of the projector for initial information
about a problem.

Symptom The projector will not turn on when is pressed...
CAUSE / REMEDY:

1. Make sure to hold for approximately one second. Or press quickly and release, and fol-

low with .

2. Do both LEDs come on at the rear of the projector? Check that the power cord is properly

connected at the wall outlet (100-240 VAC, 50-60 Hz nominal) and that you are using the origi­nal high-current 13A cable provided.

3. Does the green “Status” LED flash with each key press? If not, the projector is not receiving

the keypad’s IR signals. Ensure the keypad is directed at either the front or rear of the projector,
or at the screen. Also make sure that these paths are not blocked. Try the built-in keypad.

4. The batteries in the IR remote keypad may be weak. Refer to 4.3, Replacing Keypad

Batteries for instructions.

5. The IR keypad may have been disabled by a change in protocol. See 2.10, Keypad Protocols

and Conversion and 3.7, Adjusting System Parameters and .

6. Use the key on the built-in keypad to turn the projector on.

Symptom The projector is on but I can’t see display of source input...
CAUSE / REMEDY:

1. Was the lens cover accidentally left on? Remove lens cover.

2. Is the shutter closed? Is the projector in standby? Press to clear.

3. Is an active source connected properly? Check the cable connections. And is the correct

source selected? Press , , , or to select. See 2.4, Source Connections and 3.5,
Working with Inputs and Channels for details.

4. Are there test patterns or menus present? If so, check your source connections again.

5. The room lighting may be too bright. Lower the intensity of the room lighting. Reduce light

reflections as much as possible.

MAINTENANCE

steady red? This indicates an internal system error that may prevent the projector from operat­ing. If the problem persists contact a qualified Runco service technician.

Symptom The projector does not respond to the infrared remote keypad...
CAUSE / REMEDY:

1. Does the built-in keypad work? If so, check that the keypads are enabled.

2. Does the green “Status” LED flash each time a key is pressed? If not, the projector is not

receiving the keypad’s IR signals. Ensure the keypad is directed to either the front or rear of the
projector, or towards the screen.

3. The viewing path between the IR keypad and the projector (or screen) may be blocked.

Ensure there is a clear line-of-sight between the keypad and the projector (or screen).

4. The batteries in the IR remote keypad may be weak. Refer to 4.3, Replacing Keypad

Batteries for instructions on how to replace the batteries.

5. There may be unusual lighting conditions in the room affecting IR keypad operation.

Determine if such conditions exist and correct.

6. The IR keypad may have been disabled for use with this projector(s). Press to enable

broadcasting to all projectors. See 2.10, Keypad Protocols and Conversion and 3.7, Adjusting
and Checking System Parameters for additional information.

Symptom The power is on but the lamp is not...
CAUSE / REMEDY:

1. Does the LCD status window say “warming up”?

2. The projector probably became overheated (there is likely an error code flashing and a mes-

sage in the LCD status window). Allow to cool and make sure that nothing blocks projector
vents. Do not operate in environments warmer than 35°C (95°F).

3. The lamp may have reached the end of its life. Check the “Lamp Hours” via RS-232 request

‘lph?’.

Symptom The display is jittery or unstable...
CAUSE / REMEDY:

1. If the display is jittery or if it disappears and reappears erratically, check that the source is

properly connected and that its signal is of adequate quality for detection. For example, it the
projector scans the default input for a signal to display, and a poor quality or improperly con­nected source is connected, the projector will briefly and repeatedly attempt to display an
image. If no source is connected, the “No signal present” error message appears over a blank
display. Correct the source connection.

2. The horizontal or vertical scan frequency of the input signal may be out of range of the pro-

jector. Refer to Section 5, Specifications for scan frequency ranges.

3. The sync signal may be inadequate. Correct the source problem.

4. The input signal type may conflict with the input module. Install/use the correct module for

the source.

5. Pixel tracking, phase, filter, etc. may need more adjustment.

Symptom The display is faint...
CAUSE / REMEDY:

1. Check Input Levels option-turn auto to “off”, then “on” again.

2. Brightness and/or contrast may be set too low. Adjust as necessary.

3. Gamma may be set too low. Recommended setting for most signals is 2.2.

4. The projection room may be too bright. Lower the intensity of projection room lighting and

reduce light reflections as much as possible.

5. The projector may be too far from the screen. Move the projector closer.

6. The location of the audience with respect to the screen may not be ideal. Make sure the audi-

ence is within the viewing angle set by the projector and screen position, and the screen type.

7. The source may be double terminated. Ensure the source is terminated only once.

8. The source (if non-video) may need sync tip clamping. Enter a check in the "Clamp Tip" box

found in the Input Levels submenu.

SymptomThe display is reversed and/or upside-down…
CAUSE / REMEDY:

1. The projector's image orientation is not set correctly for the current installation. Refer to 2.6,

Operating Orientation to set the projector's image orientation to match your installation.

SymptomThe upper portion of the display is waving, tearing or jittering…
CAUSE / REMEDY:

1. This can sometimes occur with video or VCR sources. If you are using a VCR, make sure

that the "VCR" option is checked (in Advanced menu).

SymptomPortions of the display are cut off or wrap to the opposite edge…
CAUSE / REMEDY:

1. Reduce top, bottom, left or right blanking from within the Size and Position menu. Check

size and position adjustments.

2. Resizing may need adjustment. Adjust until entire image is visible and centered.

SymptomThe display appears compressed or stretched…
CAUSE / REMEDY:

1. The frequency of the pixel sampling clock is incorrect for the current source.

2. The Size and Position options may be adjusted poorly for the incoming source signal. See

3.6, Adjusting the Image.

SymptomDisplay quality appears to drift from good to bad, bad to good…
CAUSE / REMEDY:

1. The operating temperature of the projector may be fluctuating. Watch that the projector is not

located too close to heating/air conditioning vents.

2. The source input signal may be of low quality.

3. The horizontal or vertical frequency of the input may have changed at the source end.

SymptomThe display has suddenly frozen, or an unknown menu has appeared…
CAUSE / REMEDY:

1. You may have accidentally entered a special engineering code using the key in combi-

nation with certain numbers, or you may have selected the "Freeze Image" option. Press
as necessary to cancel the function and return to presentation level.

2. If the screen blacks out inexplicably, it is possible that excessive voltage noise on the AC or

ground input has interrupted the projector's ability to lock on to a signal. Turn the projector off,
wait for the lamp fans to stop, and unplug. Plug in again and power up as usual.

SymptomThe display is not sharp or "clean"…
CAUSE / REMEDY:

1. More display adjustment may be required-focus, brightness, contrast, pixel tracking, pixel

phase, and detail.

2. If you are using a BNC T-connector, try using a distribution amplifier to boost signal levels.

3. Is the video input signal properly terminated? Set in Preferences menu.

4. The screen size may be too large. As screen size increases, magnification increases, reducing

brightness and clarity. See lens specifications in Section 5.

5. The source input signal may be of low quality. Try another source.

SymptomThe display is "noisy"…
CAUSE / REMEDY:

1. Display adjustment may be required. Adjust pixel tracking, phase and filter.

2. The video input may not be terminated. Make sure the video input is terminated (75 Ω). If it

is the last connection in a loop-through chain, the video input should be terminated at the last
projector only.

3. The signal cables carrying the input signal may be of poor quality. Use only good quality sig-

nal cables.

4. The distance between the input source device and the projector may be too great. If the dis-

tance between the input source device and the projector is greater than 25 feet, signal amplifica­tion/conditioning may be required.

5. The input signal may be of poor quality.

6. If the source is a VCR or off-air broadcast, detail may be set too high. Keep near 4 for most

sources.

Safety Tips

6-3

Congratulations on your purchase of the VHD Ultra Controller video processor with Vivix™ technology! This
processor is designed to maximize the image quality of your fixed-pixel display or rear-screen television while
adding an extra level of flexibility to your system. The VHD Ultra Controller's Vivix™ processing techniques
enable this processor to be used most efficiently with fixed-pixel displays, and will provide the most stunning
image that your display can possibly deliver.

Vivix™ is a proprietary technique developed by Runco engineers to match the output resolution of the
processor precisely to the display it will be used with. This precision processing technique resolves all the
problems that conventional video processors have with fixed-pixel displays, which include pixel-tracking
artifacts (jagged lines, moiré, jerky motion, etc.), too much overscan (significant loss of image) and even
improper and disproportionate aspect ratios. The results of Vivix™ technology is an image that nearly rivals
that of a CRT, while providing three geometrically-correct aspect ratios on a 16:9 or a 4:3 screen.

The VHD Ultra Controller have many great features and benefits that make it a flexible, high-quality
processor. Its many benefits include:

• Vivix

TM

Technology, which maximizes image quality and flexibility of fixed-pixel displays.

• An adaptive 2-dimensional comb filter that greatly reduces artifacts when using a composite
video signal as an input.

• A Luma edge enhancement circuit makes the edges of objects appear sharper without the ringing
and noise increase associated with traditional sharpness circuits

• A Chroma edge enhancement circuit is included to compensate for lower chroma resolution found
in composite and S-video.

• Inverse Telecine (3:2 pulldown) detection and processing allows the scaler to almost completely
eliminate interlace artifacts associated with other scalers

• The controller can correctly scale anamorphic, letterbox and 4:3 formats to fit on a wide aspect-ratio screen,
and scale anamorphic formats on a 4:3 screen

• A pass-through connector is supplied for routing HDTV or computer graphics directly to the display.

• An RS-232 input is provided for easy integration into the automated home theater environment

• A TBC (Time Base Corrector) circuit is provided for unstable sources such as VCR’s.

• 12V outputs are provided for drop screens and screen masking.

• A simple 7-button remote controls all aspects of operation. One button source selection and aspect ratio
control is also provided via the remote control.
