Follow these 7 steps for quick set up of the projector:

Position the Projector

To perform a quick setup, the projector must be positioned so that the throw
distance is the same as that used during the most recent optical alignment;
otherwise a detailed setup is required .

The throw distance is the distance

between the center lens on the projector and the center of the projection

screen. See Appendix F and Appendix G for more information.

Note: If an

optical lens alignment is required, refer to section 2.8, Optical Alignment.

Connect the Power Cord

Plug the AC line cord into the line input unit on the lower front panel of the

projector. Plug the three prong end of the line cord in a grounded AC outlet.

Notes: 1) Input voltage must be between 90 VAC and 264 VAC. 2) Ensure the

line cord is the proper type for the AC receptacle.

Connect a Source

Connect a source to the projector’s built-in RGB input (slot 1) or, for the
9500LC Ultra, the Image Shifter RGB input (slot 2). Ensure the source is on
and properly connected.

INSTALLATION & SETUP

Screen Type ●

Screen type is a very important factor when designing a projection system.
Inexperienced users or installers should always consult their dealer when
deciding on screen type.

The following guidelines may be helpful to

understand the differences between screen types.

Front Screen Installations

There are

two basic screen types: flat and curved. The choice between a flat
screen versus a curved screen is dependant on audience viewing angle and
screen gain.

There is always a trade-off between viewing angle and gain.

Viewing angles for both screen types are illustrated in Figures 2-1 and 2-2.

Flat screens offer a gain of about 1 with a viewing angle just less than 180°.
Incident light reflects equally in all directions so the audience can see the
display from various angles.

Because of the lower gain, flat screens are more

effective when ambient lighting is reduced.

Figure 2-1. Audience Coverage with Flat Screen

Figure 2-2. Audience Coverage with Curved Screen

Curved screens have gains larger than 1 and viewing angles much less than

180°. Most curved screens have different horizontal and vertical viewing
angles. Incident light does not reflect equally in all directions. The reflected
light concentrates in a conical volume or “viewing cone”. Audiences within
the viewing cone see a brighter image than that from an equal area on a flat
screen. Audiences outside the viewing cone see a dimmer image.

2-3

.

..

I

INSTALLATION

& SETUP

To summarize, curved screens are better suited for brightly lit rooms where the
audience is situated within the viewing cone.

Flat screens are best suited when

a wide viewing angle is required and ambient room lighting (near the screen)

is low.

Note: Screen Gain is defined in Appendix A, Glossaty.

Rear Screen Installations

There are two basic types of rear screens: diffised and optical. A diffused
screen has a surface which 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.

Optical 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, optical screens are better suited for brightly lit rooms where the

audience is situated within the viewing cone.

Diffused screens are best suited

when a wide viewing angle is required but there is low ambient room lighting.

Screen Size and ●

Screen size and throw distance are interrelated. See Appendices F and G. As

Throw Distance

screen size increases, the distance between the projector and the screen also
increases. During projection room design, make sure that the room can
accommodate the required position of the projector for the screen size you
need.

Screen Size

Screen sizes vary according to model and lens type. See Appendices F and G.
Choose a screen size which is appropriate for your application. If the projector

will be used to display text information it is important that the image size
allows the audience to clearly resolve all text. 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 not be legible at a distance even

though it is projected sharply and clearly on the screen.

To fill a screen with an image, the aspect ratio of the screen must 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 video from a VCR has a 4:3 or 1.33:1 aspect

ratio. For example, to display a VCR output 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 ofien specified as diagonal size. Screensspecified by,

diagonal size have aspect ratios of 4:3. Screens with other aspect ratios are

not typically specij7ed by diagonal size.

2-4

Throw Distance

INSTALLATION & SETUP

The throw distance (projector-to-screen distance) must be determined for every
new installation. Throw distance, the distance between the projector’s center
lens and the center of the screen, is based on screen size. As screen size
increases, the distance between the projector and the screen increases. Make

sure that the room can accommodate the required position of the projector for

the chosen screen size.

Once your screen size is known you can determine the required throw distance
for your projector model and lens by using the formulas in Appendix G and
tables in Appendix F.

Notes: 1) Calculated values are for reference only. It is good practice to
simulate the setup to determine the necessary throw distance. 2)

Display size is

aflected by input signal characteristics. Once the projector is set, use the Size

function to fine tune display size.

Throw distance and projection angle:

Keep in mind that the ability to properly
focus all areas of the image is limited if a significantly tilted projector is too
close to the screen.

Lighting ●

Proper lighting is another important factor when designing a projection room.
Visiting a movie theatre can give you an idea of what makes a good projection
environment. All walls, floors and furnishings are dull colored and non­reflectively finished. Every effort should be made to create the best
environment for your system.

When designing a projection room, try to avoid white, reflective ceilings and
non-directional lighting such as fluorescent lights. The white ceiling spreads
the light which makes the room appear brighter. You want to keep the
lighting and reflections to a minimum. If it is not possible to keep fluorescent
lights off, consider using parabolic reflectors (“egg crates”) to direct light down
to the floor and away from the ceiling. Spot lighting (incandescent) is a better
way to obtain illumination. Installing light dimmers or rheostats allows you to
control your lighting environment.

Outside windows are undesirable in any projection environment. A small
crack between curtains on a sunny day can severely wash-out an image. Make

sure that curtains are opaque and fit snugly. Some curtains can provide up to

100 percent blockage of outside light. Pay close attention to the curtain

material facing inside the room. It should have a matte finish.

Even with no external light at all, reflections from room surfaces can degrade
the image. Light from the screen should be absorbed by surfaces so that it
will not be reflected back to the screen. Keep reflective surfaces to a
minimum.

INSTALLATION & SETUP

Other

Considerations

2-6

To minimize the effects caused by unwanted light from door and aisle ways,
carefully choose the position of your projector and screen. Figure 2-3 shows
an installation where poor screen placement has allowed too much unwanted
light to enter the screen.

In Figure 2-4, the screen and the projector are

positioned so that unwanted light is minimized.

Figure 2-4. Good Screen Placement

● Here are some other considerations and tips which can help you improve the

design of your projection system.

❑

❑

Proper ventilation is important. 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 which may affect performance.

Keep the projector away from devices which radiate electromagnetic energy
such as motors and transformers. Common sources of these are slide

projectors, speakers, power amplifiers, elevators, etc. Keep 35 mm slide
projectors at least 2 feet away from the projector. Even if both are not used
at the same time, the magnetic fields created by the slide projector can
cause permanent magnetization of the projector.

,----- ..

I

INSTALLATION & SETUP

IYFor rear screen applications, less space is required if a mirror is used to fold

the optical path.

❑ Choose the right screen size for your application:

.

As screen size increases, magnification increases which reduces
brightness. This reduces the contrast ratio which affects legibility. Sharp
defined edges become soft and fuzzy. Consider whether screen size is
more important.

.

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.

“ Larger screens require greater attention to lighting conditions.

❑ When laying out your projection room, consider positioning the projector

and screen in a manner which 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 2-5 shows two
examples of how audience coverage is maximized.

This section explains: how to convert the keypad from a built-in keypad to a
remote keypad, how to change keypad protocol and backlit settings, and how
to determine if reverse scan setup is required.

The projector includes a multi-use full-function keypad which may be
configured for use as a built-in, IR remote, or wired remote keypad. The
keypad is configured at the factory for built-in use. It is located below the
front top cover. You can use the keypad as it is or re-configure it for remote
operation. You can also “hard wire” the keypad to be a protocol A or
protocol B keypad (see section 3.7,

Utility Features for information about

keypad protocols).

& SETUP

This jumper setting is important if the keypad is configured for remote
operation. There are two keypad protocols: A and B. These protocols are
available to allow two projectors in the same room to be independently
controlled by separate remote keypads.

The protocol setting of the keypad

must match that set in the projector’s Keypad Options menu ( [~ IZIEl ).

For

more information about keypad protocols, refer to the Remote

Control Options

entry in section 3.7, Utility Features.

JP2

This jumper must always be set between pins 1 and 2 as shown; otherwise, the
projector will not respond correctly to keypad commands.

JP3
This jumper must always be set between pins 1 and 2 as shown; otherwise, the

backlit feature will be disabled and the projector will not respond correctly to
keypad commands.

JP4
The JP4 jumper setting sets the keypad type. If you are converting the keypad

to an IR remote, move the JP4 jumper from between pins 2 and 3 to between
pins 1 and 2.

Step 3

For an IR remote keypad, place four AA size, 1.5V alkaline batteries in the
compartment ensuring that the +/- orientation of each battery is correct.
Position the compartment door into place.

For a wired remote keypad, an optional accessory cable (#03-001106-O2P) is
required. Plug the cable into the cable connector then position the door into
place. Plug the cable jack into the remote jack input on the projector.

In situations where the space behind the projector is limited, a mirror may be
used to fold the optical path as illustrated in Figure 2-14. If a diffused screen
is used, the projection angle 0 should be less than 15°. If an optical screen is
used, the optical path between the mirror and the screen should be perpen­dicular to the screen. Much attention must be given to the positioning of the
projector and the mirror. This can be quite difficult for installers unfamiliar
with this type of installation.

It is recommended that your dealer or an

Optional interface modules are available to accommodate other signal types.
These include a Composite/S-Video Module, an HDTV Input Module, and a
PC Analog Input Module. Any one of these can be installed in slot 2. A
Marquee Multi-Standard Decoder may be installed to add four additiomd
inputs to the system (“slots” 3 to 6). To further increase the number of inputs,
a signal switcher may be connected to the RGB interface in slot 1 to add 8
more sources to the system (9 switcher inputs replace one RGB input). Other
switchers may be connected to the first switcher for more inputs. Brief
descriptions of the above mentioned optional modules are given in Appendix

INSTALLATION & SETUP

The

two RGB interfaces provided allow connection of an RGB source having

one of the following sync types: sync on green, composite sync, or separate H
& V sync. To comect a source, connect the red, green, and blue outputs to
the RED, GREEN, and BLUE inputs on the interface. If the souce uses

sync

on green, no additional cables are required.

If the source provides a composite

sync output, connect it to the HOIUCOMP input. If the source provides
separate horizontal and vertical sync outputs, connect the horizontal sync
signal to the HORfCOMP input, and connect the vertical sync input to the
VERT inuut. Interconnection cables must be terminated with BNC connectors.

To control audio levels in an audio/visual system, pre-amplified (line level)
audio inputs are connected to the left and right channel audio inputs on the
interfaces. Audio outputs from the built-in interface are then connected to
external audio amplification equipment for sound output. All audio connection
cables require standard RCA type phono plugs.

INSTALLATION

2.8 Optical
Alignment

& SETUP

If using the projector with a

Marquee signal switcher, connect an RS-232

serial communication cable between the switcher and the projector serial port
labelled “SWITCHER”. If the projector is to be controlled by a computer or
controller which has an RS-232 serial port, connect an RS-232 serial cable
between the computer and the projector serial port labelled “IN”. After the

connection is made, set the serial port baud rate as described in the Projector

Setup entry in section 3.7,

Utilities.

Notes: 1) All serial connections require a 9 pin D connector at the projector

end. Refer to Appendix D for cable wiring requirements. 2) For

computerlcontroiler control, PC sojiware is required. 3) The RS-232 serial

port labelled “OUT” is provided for projector networking applications.

Optical alignment is required when the throw distance changes or the projector

cannot be focused using the focus controls.

The projector is optically aligned
at the factory at a fixed screen size and a fixed projector-to-screen distance.
See Appendices F and G for the specific details needed for your projector
model and lens. If the throw distance has changed since the last setup, proceed
as follows:

Notes: 1) The projector must be warmed up for at least 45 minutes prior to

peq%orming optical alignment.

2) Optical alignment is both a mechanical and
electrical adjustment. Electrical adjustments are stored in the current setup
memory. After alignment is complete, setup memories which were previously
set up (if any) must be set up again. Memory setup is explained in

section 2.10. 3) Factory alignment is pe~ormed using the internal crosshatch
with a 61.8 kHz signal applied.

It is recommended that optical alignment be performed using the projector’s
Guided Mechanical Setup tutorial. This tutorial displays step-by-step
instructions during the alignment. The instructions in this section require use
of the Guided Me~hanical_Setup tutorial.

provided with the projector. The driver is used for lens alignment.

Examine the lenses and hardware as shown in Figure 2-21a (or, for the 8500
model, see Figure 2-21b). Each lens consists of a rear section and a front
section. The rear section sets the optical focus at the center of the image and is
secured to the lens body by a wing nut at the top rear of the lens assembly.
The front section sets the focus at the corners and is secured to the rear section
by a wing nut at the top front of the lens assembly.
