The HJT Model 100 Projector can be controlled by the Executive IR remote, the
Technician IR remote or a computer. One of these IR remote controllers is supplied with
the projector. Both remotes per form the same functions when operated through the
menu tree. This chapter assumes the projector is being operated using the Executive
Remote control.
3.1. Executive Remote
The Executive Remote Control can be used as an infrared or t ethered remote
(see Figure 3.0-1 on page 3-2) . I f using the Executive remote as an IR, do not
plug in the tether cable. If using with the tether, plug one end of t he 8 meter tether
cable into the remote and the other end into t he phone jack (see Figure 3-8) on
the projector’s rear panel. One (1) end of the tether cable is terminated in a phone
jack and the other end has a telephone jack. The IR function is disabled when the
tether cable is plugged into the r em ote. All setup, image, and raster adjustments
are made with the Executive Remote by navigating through the m enu t ree (refer
to Menu Structure Diagram, Figur e 3.0-3 on page 3-11).
The Executive Remote has a maximum range of about 16 m et e r s (line of sight
only) when using the IR transmitter. It does not transmit effectively through a
rear-screen window.

3.6.3. To Choose Full or Short Menus
Full menus are necessary to perform timing, geometry, convergence, and
maintenance. Short menus allow very limited menu selections such as
picture settings and channel selection. The short menu is useful for
certain situations such as:
The projector is already set up and operating ;
Frequent channel changes are occurring;
Changes in picture settings are of ten necessary.
Short menus also prevent inadvertent changes fr om occur r ing to the
timing, geometry, or converg ence set up dat a when several operators ar e

If there is no source file on t he selected channel to handle the source to be

If there is no acceptable source f ile set up on any other channel to attach to the
selected channel, a source file must be created ( s et up) to handle the source to
be viewed. Procedures for setting up source files ar e covered in Chapt er 4.
3.8. Selecting a Channel
A channel is an Autoselect group of up to twenty (20) sour ce files set up to
receive different video sources within any one (1) VIC slot or port.
3-12 Hughes-JVC Technology Corporation
Chapter 3—Operation
NOTE: The Autoselect featur e m eans t hat when the incoming source changes in
the active channel, the projector automatically selects and switches to the sour ce
file within that channel that most closely matches the incom ing source's
parameters. The channel selected must have a source file set up to handle the
type of incoming video or graphic source. T he t er m s “source” and “source file” are
often used interchangeably (refer to Table 3.0-6 for definitions).
The procedures in Chapter 4 are for setting up a new source file for a new
source. The resultant geomet r ic and converg ence data in the new source file can
then be "attached" to different channels (refer to Section 3. 9). The Geometry and
Convergence settings on these attached sources must be adjusted with care—
adjustments made on attached sources will alter the dat a for all channels
attached to the source file. Not e t hat the setup data is being shared by all
channels attached to the source file by the attached sour ce from the original
source file.

A source is defined as an input signal with a specific set of parameters such as
horizontal/vertical scan rates, interlaced or noninter laced scanning, and sync
type/polarity. An incoming source can be attached to a source file that was
previously set up for a different sour ce. The attached source is using the setup
data from the orig inal sour ce file.

NOTE: Setup procedures for new sources are covered beginning with
Section 4.1. on page 4-2. When setting up a source file for a new source,
the operator:
1. Connects the source to the side panel input jacks;
2. Selects the channel to receive that source;
3. Names the channel to show the source type;
4. Selects the VIC slot and/or VIC port to handle that source ( if the projector
uses an optional or a multi-port VIC);
5. Follows the adjustment procedures in Chapter 4 on page 4-37
to set up a source file to handle that specific source.
Once a source has been set up, it can be “attached” to another channel.
To “attach a source” means that an original source file and its geometry and
convergence parameters are being used by another source input signal.
3-14 Hughes-JVC Technology Corporation
Chapter 3—Operation
The attached sources are using the same source files (they ar e the same source
files—not copies).
A source can be attached to a source file from a different channel. Geometry and
convergence settings must not be adjusted on at t ached sour ces because all
attached sources will then be altered by the same adjustment. This is only true for
geometry, convergence and ILA
®
settings. Timing and picture set t ings come into
the attached source at the default levels and may be adjusted without affecting
the original source or any other attached source.
Two (2) identical sources can be located in two (2) diff er ent channels with two (2)
distinctly different pictur e set tings for use with possibly different room
environments. For example, differ ent brightness and contrast settings could be
used for the same source in two (2) dif ferent channels, saving the time of
repeatedly adjusting contrast and bright ness.
NOTE: One channels’ source file parameters can be copied and used as st arting
points to set up new sources in other channels. The first channel may be copied
to a second channel. Follow the procedure in Section 4.10 on page 4-38 about
Backing up Settings. T he channel ( groups of source files) can be customized to
suit whatever purposes are needed.
Each channel is capable of handling up to 20 different sources. There are 99

This chapter assumes the operator is using a r em ote control and accessing setup
functions through the menu t r ee. All instructions are given with reference to using t he
menu tree for setup f unctions. If using a PC or laptop computer to control the projector
refer to Table 3.0-10 on page 3-23 for the equivalent key f unct ions.
Chapter 3 covered mainly operation for project o r s that are already positioned, set up,
and ready for operation. This chapter covers the com plet e projector setup procedures.
Prior to starting the procedur es in t his chapter, the operator should review Chapter 3 to
become familiar with navigating the m enu and using the remote control keys.
Prior to performing any adjust ments, allow the projector to warm up for at least 60 minutes.
4.1. Setup Preparation

After completing the t iming, geometric, and convergence adjustments for one (1)

of the 99 channels and the source file to anot her of the 20 sources.
NOTE: When backing up a channel, ensure that the “copied to” channel is blank .

on the “copied to” channel. Refer to t he Backing up Settings function from Section
4.10 on page 4-38 for mor e det ail.
This provides backup for a previously set up channel and a good star t ing point for
setting up other channels. Also ensure that t he " c opied t o" channel uses the
same type of VIC as the "copied fr om" channel. If the projector uses only one (1)
VIC, this is not applicable.

Chapter 4—Setup Adjustments
If the projector uses m or e than one (1) type of VIC, the type can be determined
by accessing the S

menu and selecting S
TATUS LIST
. Each
VIC slot will be displayed with the type of VIC in each slot. Complete the Timing
section first, Geometr y next, and Converg ence last .
They are performed in this order because Geometry depends on proper Timing
settings and Convergence depends on correct Geometry.
Ensure that the projector is installed and positioned correctly at the outset so that
all later adjustments will be at their opt im al levels and the image will be the
sharpest possible. Positioning the projector is the most important step in the
setup procedures. The projector- to-screen alignment should be as square as
possible before starting setup procedures in order to accomplish Timing,
Geometric, and Convergence adjustments properly.
Prior to starting the procedur es, a channel and sour ce (source file) must be
selected for the setup adjustm ent s. This is covered in Section 4.1.2 on page 4-6.
A rough focus of the pr ojection lens may be necessary to be able to read the
menus.
4.1.1. Projection Lens Focus (Rough)
For the Timing and Geometry setup procedures below, it is necessary to
obtain a rough focus of t he Pr ojection Lens in order to read menus and
do the adjustments. If t he focus is adequate to read the menus, this
procedure can be skipped until after the Timing and Geometry
adjustments are finished. When the Timing and Geometry adjustments
are complete, and prior to start ing conver gence, t he Projection Lens
focus adjustment should be repeated and a sharp focus obtained.

timing of raster scanning . The Timing adjustments are universal t o RGB and color
selection is not necessary.
4.2.1. Clamp Type
Use the default clamp type unless there are sync problems with the new
signals being used.
Clamp type sets the type of clamping used with the sync pulse.
There are three (3) types of clamping;
BP (Back Porch) is used in 95% of all computer and video inputs,
Back Porch is the default;
ST (Sync Tip) is seldom used but is necessary when there is
no Back Porch to clamp on;

4.3.4. Skew/Rotate (G)
Skew and Rotate are corrected in the same procedure using the same
screen patterns. Skew distortion “leans” horizontally lik e a trapezoidal
pattern. This means the vertical center line is skewed in one (1) direction
or another causing the entire patt er n to lean in the same direction (see
Figure 4.0-7 on page 4-15). Rotation distortion is where the entire pattern
is rotated vertically or horizontally (refer to Figure 4.0-6 on page 4-15).
Use the Standard Crosshatch test patter n (shown in Figure 4.0-4 on
page 4-13) to spot Skew or Rotation distortion. If the vertical centerline is
vertical and the horizontal centerline is horizontal, the Sk ew setting is
correct (as described in Section 4.3.7 on page 4- 18) and should not be
changed.
Perform the Rotate pr ocedure first to make the horizontal lines horizontal.
If the pattern leans left or right (as illustrated in Figure 4.0-7 on page 4-

4.6. Convergence (XY Registration)
Convergence (XY Registration) overlays the CRT beams onto each other.
XY Registration procedures are required to align the Red, Blue, and Green CRT
beams together on the screen.
NOTE: For a better understanding of what is being accomplished, take the tim e
now to read the entire Convergence (XY Registr at ion) sect ion before making any
adjustments.
4.6.1. Purpose of Convergence
The XY Convergence adjustments are used t o converg e or overlay the
Red, Green and Blue CRT images over the entir e screen area. The HJT
Model 100 Projector handles many different sources and convergence is
tied directly to a video source. One (1) channel can contain up to 20
different sources with different formats. Each of these sources must have
its own set of convergence data.
4.6.2. Cursor Shapes and Sizes
Three (3) diff er ent cur s or m odes ( as described in Table 4.0-3) are used
to make adjustments.
Table 4.0-3 Cursor Modes
Cursor Mode Description
Move
Size
Adjust
Various cursor sizes are available to adjust areas. Some areas may
require odd shaped cursors. If a long thin area appears out of
convergence, use a long thin cursor shaped like t he area. Use the cursor
size that best fits the area. Some ar eas m ay be satisfactory and will not
need any convergence corrections.
The greatest convergence correct ions ar e m ade at the center of the
cursor—avoid making corrections at the edg es of the cursor. Move the
center of the cursor over the area t hat needs cor recting. A cursor with a
long centerline is affected equally all along its centerline by the
adjustments.

4-24 Hughes-JVC Technology Corporation
4.6.3. Convergence Profiled
Start with a full-size cursor when the entire screen needs adjusting.
To converge (XY Registration):
1. Start with the center of the cursor at the upper left corner.
Note that cursor is off the screen at the top and left (see Figure 4.012 on page 4-26).
2. Make corrections to the area and then, move the center of the cursor
to the numbered areas shown in Figure 4.0-12 in the seq uence
shown.
3. Size down to a ¼ screen cursor size. Move down and across the
screen in the sequence shown in Figure 4.0-13—in most cases it will
not be necessary to use a cursor smaller than the one shown.
4. If there are still some smaller areas that need convergence,
size down to a cursor that encloses about nine (9) of the rect angles.
Use the same general pattern as with the previous cursors.
