Safety Information  
If there is any visible damage to the power cable, disconnect power to the  
projector until the damaged cable is replaced. Install the projector on a smooth,  
vibration-resistant level surface, or ceiling mount, in an area free from dust and  
moisture. Do not place the equipment near heat-radiating appliances. Smoke and  
steam could adversely affect the internal components.  
If mounting the projector, use hardware that can handle a minimum of three (3)  
times the projector weight. In ceiling mounted applications, always use approved  
hardware and installation methods.  
0.3. Heat Safeguards  
0.3.1. Fans and Ventilation  
Do not  
The projector has multiple fans to cool the projector system.  
block the intake or outflow of any fans.  
Heat is emitted within the  
system and must be vented to keep the system running. Blocking air  
intake or exhaust ports could cause the projector to overheat. Do not  
enclose the unit in a restricted space (refer to physical access and  
thermal clearance illustration guidelines).  
If a foreign object falls inside the projector, immediately unplug the  
projector and call a Hughes-JVC certified technician for object removal.  
CAUTION!!! Do not unplug the power cord until after the  
arc lamp fan has stopped running. This fan protects the arc lamp from  
overheating.  
0.4. Light Safeguards  
Do Not Open The Projector Cover.  
Dangerous high voltage, bright light,  
ultraviolet, and infrared radiation can be hazardous to personnel.  
Access must remain restricted to  
Hughes-JVC authorized maintenance  
personnel.  
Do Not  
look into the output of the Lighted Projection Lens or the side exhaust fan  
while the projector is on.  
Do Not  
look directly into the projection lens from any distrance. Exposure to  
projection light can cause eye injury.

The HJT Model 100 Projector accepts a variety of inputs and operates with a wide range  
of frame and raster rates. The projector meets these requirements with sophisticated  
computer terminal control, a unique optics system, a high-powered projection arc lamp  
ILA®  
and the Hughes-JVC unique  
(Image Light Amplifier) assembly.  
The projector is intended to be used for the projection of video and graphics, as shown  
in this manual. It should not be used for purposes it was not designed for.  
1.1. Shipping and Inspection  
The projector is shipped in a standard shipping container which is not reusable.  
A reusable container is optional and recommended if the projector is moved and shipped  
often. The containers are equipped with tilt and drop indicators to assist in determining if  
the projector was handled properly during shipping.  
Upon arrival, inspect the container for any abnormal readings, dents, gouges and any  
other evidence of rough handling. Immediately report any abnormal readings or  
conditions to the shipping company.  
After removing the projector from the shipping container, inspect the projector’s exterior  
for signs of shipping damage like scratches, abrasions, cracks on paint, or other  
surfaces. Report any damage to your shipping company immediately.

2.1. Air Flow and Maintenance Clearances  
The HJT Model 100 Projector should be placed in a location where it is easily accessible  
on both right and left sides. The area should be well ventilated, and the projector air  
intakes and exhausts should not be blocked in any way.  
2.1.1. Air Flow  
The HJT Model 100 Projector dissipates 4,100 BTUs/hr and must not be placed in an  
enclosure that would limit air flow. Adequate ventilation is necessary to provide proper air  
flow to prevent overheating. For optimum operation, maintain the following air flow  
clearances around the projector for proper heat venting.  
The HJT Model 100 Projector should be placed in a location where it is easily accessible  
on both sides. The area should be well ventilated and the air intakes and exhausts  
should not be blocked in any way. For best operation, refer to

2.4. Projector-to-Screen Distance and Alignment  
Set the projector to the proper distance from the screen as determined by the  
screen width and lens ratio illustration (refer to Figure 2.0-7 on page 2-7).  
The Lens Pattern illustrated in Figure 2.0-8 on page 2-8 will help determine the  
optimal screen widths and throw distances for the zoom lens.  
The maximum projector-to-screen vertical tilt angle for a table or ceiling mount is  
15º vertical. Any tilt greater than 15º will result in a severe keystone error that  
cannot be corrected by the Keystone adjustment.  
The HJT Model 100 Projector can be used upright or downright at any angle  
from 5° to 85°.  
Figure 2.0-5 Maximum Projector-to-Screen Vertical Tilt Angle  
for table mounting, front or rear projection.

2.5. Lens Throw Distance and Screen Width  
The distance from the closest point of the screen to the projector is known  
as the throw distance.  
Table 2.0-3 Lens Definitions  
Phrase  
Throw distance Distance from the projector lens to the closest point on the screen.  
Screen width  
Maximum width of picture that can be displayed.  
Definition  
To determine the throw distance from the projector to the screen, multiply the  
screen width by the lens ratio.  
For instance, if the projection lens being used is the 1.5:1 lens and the desired  
screen width is 3.65 meters (12 feet), the distance from the closest point of the  
screen to the projector lens is 5.48 meters (18 feet), as illustrated in Table 2.0-4.

2.8. Sources  
The projector accommodates a wide range of formats from standard composite  
video to a multitude of computer graphics standard. It is critical to set up the  
projectors source files to accommodate this range. Key parameters are the  
horizontal and vertical scan rates, interlaced or non-interlaced scanning, and  
plus/minus sync levels. The projector can handle up to 20 sources in one  
channel. The correct projector source file is matched and automatically selected  
for the source being received by the projector.  
2.8.1. Types of Standard Composite Signals  
There are a number of different standards for composite video.  
These standards differ in relation to parameters such as signal timing and  
the encoding scheme for the "video" information.

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 perform 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 tethered remote  
(see Figure 3.0-1 on page 3-2). If using the Executive remote as an IR, do not  
plug in the tether cable. If using with the tether, plug one end of the 8 meter tether  
cable into the remote and the other end into the phone jack (see Figure 3-8) on  
the projectors 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 remote. All setup, image, and raster adjustments  
are made with the Executive Remote by navigating through the menu tree (refer  
to Menu Structure Diagram, Figure 3.0-3 on page 3-11).  
The Executive Remote has a maximum range of about 16 meters (line of sight  
only) when using the IR transmitter. It does not transmit effectively through a  
rear-screen window.

3.2. Technician Remote  
The Technician Remote provides quicker access to some functions by using keys  
on the remote. In the Menu Structure Diagram (Figure 3.0-3 on page 3-11), these  
direct access functions are indicated by a symbol after the function name. Direct  
access features eliminate the need to access functions via the menu structure  
and save time during set up.  
The Technician Remote can be used as an IR remote or with a tether like the  
Standard Remote. An 8 meter tether cable is provided with the Technician  
Remote. Inserting the tether cable disables the IR transmitter. See Figure 3.0-2  
on page 3-4 for an illustration of the Technician Remote control keys and Table  
3.0-1 on page 3-5 for key function and usage.  
The Technician Remote has a maximum range of about 16 meters, line-of-sight,  
when using an IR transmitter. It does not transmit effectively through a rear-  
screen window.

NOTE: To use a factory-preset source file, first copy it to another source number  
to keep it intact for future, then use Backing up Settings procedure on page 4-38.  
To use a factory-preset source file:  
1. Highlight the channel with the desired source file and attach it to the  
highlighted channel (see Section 3.8 on page 3-12).  
2. Note that any adjustments to the attachedsource will also alter the data  
from the original factory source file.  
3.5.1. Internal Source  
Every channel has a preset internal source shown as SOURCE 0 on the  
SOURCES list. This is factory set default timingfor the projector with  
scanning rates of 33.3kHz (horizontal) and 59.3Hz (vertical) and is similar  
to HDTV. This internal source is used to display menus when there is no  
source input connected to the projector. To use this internal source,  
select CHANNEL 0, then press ENTER. This internal source can be copied  
to any other channel but it cannot be cut, edited, or pasted to.  
3.6. Navigating the Menu  
The basic procedure for navigating the menu is explained on the top left of Figure  
3.0-3 Menu Structure Diagram on page 3-11. Examples for displaying the menu,  
making preference selections, and setup selections are shown in the following  
sections.

Chapter 2Installation  
3.6.1. Displaying the Main Menu  
The MAIN MENU is displayed on the screen when the MENU key is  
pressed. If another menu is already being shown on the screen, press the  
ESCAPE KEY (ESC) until you get back to the MAIN MENU. The menus stay  
on the screen for 60 seconds, then time out and go off the screen.  
3.6.2. Choosing Numbered Menus  
Menu selections are made with the remote using menus with or without  
numbers. This optional selection is made under PREFERENCES. Menus  
without numbers may be preferred when using SHORT MENUS (see  
Section 3.12 on page 3-21). Numbered menus allow for faster access  
and may be preferred during projector set-up.  
To choose numbered menus:  
1. Press MENU to display the MAIN MENU.  
2. Use the up/down arrow keys to highlight SYSTEM, and press ENTER  
(or select SYSTEM at the MAIN MENU).  
3. From the SYSTEM MENU, use the arrows keys to highlight  
PREFERENCES, and press ENTER (or select PREFERENCES at the  
SYSTEM MENU).  
4. From PREFERENCES select NUMBERED MENUS and press ENTER to  
toggle the NUMBERED MENUS box to select menus with or without  
numbers (checked box = menus with numbers).  
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 often necessary.  
Short menus also prevent inadvertent changes from occurring to the  
timing, geometry, or convergence setup data when several operators are  
handling the remote.  
To select short or full menus:  
1. From the MAIN MENU select FULL MENUS.  
2. Press ENTER to toggle to full or short menus (checked box = full menus).  
For the Full Menu Tree, see Figure 3.0-3 on page 3-11.  
For the Short Menu Tree, see Figure 3.0-6 on page 3-21.  
Unless otherwise noted, the procedures in this manual use the Executive  
or Technician remote, the menu tree and numbered, full menus.

3.6.4. Menu Selection Examples  
Three (3) examples of selections made using numbered menus follow.  
See Figure 3.0-3 on page 3-11 for a Menu Structure Diagram.  
To select the test pattern for Linearity:  
1. Press MENU (and ESCAPE, if necessary) to display the MAIN MENU.  
2. Select the SYSTEM menu.  
3. From the SYSTEM menu, select TEST PATTERN.  
4. From the TEST PATTERN list, select X-HATCH.  
5. The standard crosshatch test pattern appears on the screen.  
To select Linearity for adjustment purposes:  
(Continue from the above test pattern selection.)  
1. Press MENU and/or ESCAPE to display the MAIN MENU.  
2. Select the GEOMETRY menu.  
3. From the GEOMETRY menu, select LINEARITY.  
4. The Linearity adjustment window appears on the screen.  
NOTE: It is also possible to move from side to side in the menu tree.  
For example, when in the SYSTEM menu, #7, (above first example) to  
go to #4, TIMING, (above second example) press the left arrow three  
(3) times to move three (3) places to the left. To move back to the  
SYSTEM menu, press the right arrow three (3) times. During setup  
adjustments this feature can save time when moving between Picture,  
Timing, Geometry, and Convergence.  
To select a Video Switcher:  
1. Under MENU SETUP, Port A or Port B device, select VIDEO SWITCHER.  
2. Select a baud speed of 9600 if the switcher is connected to Port A  
OR a speed of 19200 if the switcher is connected to Port B.  
NOTE: Switchers are recommended to be connected to Port B.  
This allows for BOOT MANAGER to be connected to Port A through the  
ANSI terminal when software upgrades are needed without the need  
for reconfiguring the ports.  
3. Turn power off with the remote, or PC to shut the system down.  
4. Restart the system to activate changes (cycle AC power off and back on).  
Add a third digit to VIC channel assignment to show that a switcher is  
being used (see Section 4.11 on page 4-39 about Video Input Cards).

3.7. Full Menu Structure  
To view the MAIN MENU, press MENU on the remote. The MAIN MENU displays on  
the screen.  
NOTE: If another menu is displayed, press ESCAPE repeatedly until the MAIN  
MENU appears.  
Menu screens remain active for approximately 60 seconds, then the menu "times  
out" and is cleared from the screen. To issue a command, press MENU and the  
number of your selection.  
Figure 3.0-3 on page 3-11 shows the MAIN MENU Structure and the submenus.  
For a description of each menu item see Section 3.11 on page 3-17.  
After becoming familiar with navigating the menu, the next step is to select a  
channel. This is explained in Section 3.8 on page 3-12. Be sure that the channel  
selected has a source file set up to handle the type of graphic source to be  
viewed. Observe the list of sources on the selected channel to confirm this. Refer  
to 3.9 on page 3-14 for information on attaching a source. See Table 3.0-6 for  
definitions of terms.  
Table 3.0-6 Channel and Source Definitions  
Term  
Definition  
An Autoselect group of up to 20 source files, using one (1) specific  
VIC/switch number, set up to accept up to 20 sources with  
different parameters such as horizontal and vertical scanning  
rates, interlaced/noninterlaced scanning, ± sync levels.  
A channel defines the input path for a source.  
Channel  
A specific input format such as VGA, HDTV, NTSC etc. with a given  
set of parameters such as horizontal and vertical scanning rates,  
interlaced/noninterlaced scanning, and sync source/polarity.  
Source  
Data set in the projectors memory created to handle a specific  
video source. Source files must be set up to match the specific  
geometric and convergence parameters in the incoming source.  
Source File  
If there is no source file on the selected channel to handle the source to be  
viewed, the proper source file can be attached from the source list to the selected  
channel. Refer to Section 3.9 on page 3-14 for procedures for attaching a source.  
If there is no acceptable source file set up on any other channel to attach to the  
selected channel, a source file must be created (set up) to handle the source to  
be viewed. Procedures for setting up source files are covered in Chapter 4.  
3.8. Selecting a Channel  
A channel is an Autoselect group of up to twenty (20) source files set up to  
receive different video sources within any one (1) VIC slot or port.  
3-12  
Hughes-JVC Technology Corporation

Chapter 3Operation  
NOTE: The Autoselect feature means that when the incoming source changes in  
the active channel, the projector automatically selects and switches to the source  
file within that channel that most closely matches the incoming source's  
parameters. The channel selected must have a source file set up to handle the  
type of incoming video or graphic source. The terms sourceand source fileare  
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 geometric and convergence 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 data for all channels  
attached to the source file. Note that the setup data is being shared by all  
channels attached to the source file by the attached source from the original  
source file.  
To select a Channel from the Menu System :  
1. Press MENU to display the MAIN MENU.  
2. Press #2, CHANNELS from the MAIN MENU.  
3. Enter channel number using the number keys.  
4. Press ENTER once to highlight the selected channel. Press ENTER again to  
activate the highlighted channel. If using arrow keys, scroll to highlight the  
desired channel and press ENTER once.  
5. If the active channel contains more than one (1) source file for the incoming  
video source, the closest match will be automatically selected.  
NOTE: If the channel number is known, it may be selected by pressing the  
channel number, then pressing ENTER.  
3.8.1. Active Channel  
Press ENTER with no numbers preceding it, and the active channel  
number will display on the screen for three (3) seconds, provided the  
ONSCRN display mode is ON.  
In the CHANNELS MENU the active channel is shown with a pointer to the  
left of the number (as long as the active channel number is on the  
screen list).  
NOTE: Do not confuse the active channel with the highlighted channel.  
The active channel is the channel that is on screen. The highlighted  
channel is the channel that has been scrolled to with the arrow keys or  
selected by pressing its number and ENTER, but has not yet been made  
active by pressing ENTER again.  
Pressing the channel number and ENTER highlightsthe channel on the  
CHANNELS list. Pressing ENTER again makes it active(on screen).  
Sources may be attached (see Section 3.9) to the highlighted channel,  
while another channel is active.  
The active channel is displayed in the upper right corner of the  
CHANNELS MENU. See Figure 3.0-4 for an illustration of the CHANNELS  
MENU and active/highlighted channels.

3.9. Attaching a Source  
A source is defined as an input signal with a specific set of parameters such as  
horizontal/vertical scan rates, interlaced or noninterlaced scanning, and sync  
type/polarity. An incoming source can be attached to a source file that was  
previously set up for a different source. The attached source is using the setup  
data from the original source 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 attachedto another channel.  
To attach a sourcemeans that an original source file and its geometry and  
convergence parameters are being used by another source input signal.

Chapter 3Operation  
The attached sources are using the same source files (they are the same source  
filesnot copies).  
A source can be attached to a source file from a different channel. Geometry and  
convergence settings must not be adjusted on attached sources 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 settings 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) different channels with two (2)  
distinctly different picture settings for use with possibly different room  
environments. For example, different brightness and contrast settings could be  
used for the same source in two (2) different channels, saving the time of  
repeatedly adjusting contrast and brightness.  
NOTE: One channelssource file parameters can be copied and used as starting  
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. The 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  
channels (groups of source files) available. The maximum number of  
channel/source combinations is 200.  
To attach a source to a channel:  
1. Press MENU to display the MAIN MENU.  
2. From the MAIN MENU select CHANNELS.  
3. From the CHANNELS list, press the number of the channel to attach the source  
to. If the channel is not highlighted press ENTER to highlight the channel.  
Do not press ENTER if the channel is already highlighted (this would make the  
channel active).  
4. Press the right arrow key to move to the SOURCES list.  
5. Use the arrow keys and scroll to highlight the source desired.  
6. Press ENTER to attach the highlighted source to the channel that is  
highlighted in the CHANNELS list.  
Do not make any adjustments to geometry  
or convergence on these attachedsources. Any adjustments will also  
CAUTION!!!  
alter the original source file data and other attached sources.

This chapter assumes the operator is using a remote control and accessing setup  
functions through the menu tree. All instructions are given with reference to using the  
menu tree for setup functions. 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 functions.  
Chapter 3 covered mainly operation for projectors that are already positioned, set up,  
and ready for operation. This chapter covers the complete projector setup procedures.  
Prior to starting the procedures in this chapter, the operator should review Chapter 3 to  
become familiar with navigating the menu and using the remote control keys.  
Prior to performing any adjustments, allow the projector to warm up for at least 60 minutes.  
4.1. Setup Preparation  
In the Timing and Geometric adjustments below, Green is the active and  
on-screen color. Red and Blue are hidden because they track on Green.  
When the Timing and Geometric adjustments in this section are finished,  
Red and Blue is then centered to match Green and converged onto Green in the  
Convergence procedures. To hide Red and Blue, toggle the RGB key to RED,  
press HIDE, then toggle to BLUE and press HIDE. Green is now the only color  
displayed on the screen. Toggle the RGB KEY to highlight G.  
To avoid redundancy in the procedures in this chapter, some general information,  
instructions, phrases, and definitions are given below.

Procedures  
General Information  
Verify that ONSCRN key is toggled to ON if the screen does not show  
the window or menu correctly.  
When performing ILA® SENSITIVITY AND BIAS, BLACK LEVEL (G2),  
SENSITIVITY OFFSET, and UNIFORMITY (SHADING), verify that the  
SHUTTERS ON HIDE box under the SYSTEM-PREFERENCES menu is  
checked. Checking this box activates the shutter mechanism to  
hide the ILA® images and provides easier, more accurate settings  
of these adjustments.  
On single-axis adjustments such as PICTURE SETTINGS, G2,  
THRESHOLD, SENSITIVITY, ILA® BIAS etc. up/down arrow keys are  
shown on the screenleft/right arrow keys, though not shown, will  
also accomplish the same adjustments.  
After completing the timing, geometric, and convergence adjustments for one (1)  
source, the adjustment data may be backed up by copying the channel to another  
of the 99 channels and the source file to another of the 20 sources.  
NOTE: When backing up a channel, ensure that the copied tochannel is blank.  
Channel paste is only allowed to cutempty channel. Source paste will overwrite  
current source geometry, convergence and ILA® settings. All data will be deleted  
on the copied tochannel. Refer to the Backing up Settings function from Section  
4.10 on page 4-38 for more detail.  
This provides backup for a previously set up channel and a good starting point for  
setting up other channels. Also ensure that the "copied to" channel uses the  
same type of VIC as the "copied from" channel. If the projector uses only one (1)  
VIC, this is not applicable.

Chapter 4Setup Adjustments  
If the projector uses more than one (1) type of VIC, the type can be determined  
by accessing the SYSTEM-MAINTENANCE menu and selecting STATUS LIST. Each  
VIC slot will be displayed with the type of VIC in each slot. Complete the Timing  
section first, Geometry next, and Convergence 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 optimal 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 procedures, a channel and source (source file) must be  
selected for the setup adjustments. This is covered in Section 4.1.2 on page 4-6.  
A rough focus of the projection 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 the Projection Lens in order to read menus and  
do the adjustments. If the 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 starting convergence, the Projection Lens  
focus adjustment should be repeated and a sharp focus obtained.  
To obtain a Rough Focus of the Projection Lens:  
1. Press MENU to display the MAIN MENU on the screen.  
If necessary, use the ESCAPE key to back out to the MAIN MENU.  
2. Select SYSTEM from the MAIN MENU.  
3. Select TEST PATTERN from the SYSTEM menu.  
4. Select FOCUS from the TEST PATTERN menu.  
NOTE: The H pattern is preferred for focusing the Projection Lens.  
5. Select PROJECTION LENS from the SYSTEM menu.  
6. A small window displaying FOCUS and ZOOM arrows appears on the  
screen.  
7. Use the up/down arrow keys to zoom the image to the desired size.  
The raster and image should be smaller than the screen. Ensure the  
FOCUS ENABLE box in the PREFERENCES menu is checked.  
8. Use the right/left arrow keys to get a rough overall focus to be able to  
read menus. A sharper focus will be obtained later after the Geometry  
procedures are completed.  
9. Press ENTER to complete this adjustment.  
10. Press ESCAPE twice to display the MAIN MENU.

4.1.2. Editing Channels, Sources, and VICs  
Select CHANNEL and SOURCE files from the CHANNELS and SOURCES lists  
(see Section 3.8 on page 3-12). Edit the CHANNELSand SOURCES lists to  
select a name for the new channel, VIC, and source. Figure 4.0-1and  
Figure 4.0-2 illustrate the CHANNELS and SOURCESlists showing active”  
and highlightedchannels and sources. Verify that the projector is  
receiving the appropriate source.  
If the active channel receives a source that  
CAUTION!!!  
does not have an exact match in a source file, the projector will match the  
source to the source file that is closest to the new source parameters. If  
adjustments are attempted, the following statement appears on the  
screen: Adjustments are inhibited on an approximate match.The  
projector will not allow adjustments to a source file that has been set up  
for one source and is only being used now as an approximate match for  
the new source. If allowed, the adjustments would corrupt the data in the  
current source.  
To edit a Channel and Source (refer to Figure 4.0-1):  
1. Select CHANNELS from the MAIN MENU.  
2. From the CHANNELS list, select a new channel number by pressing the  
channel number, and ENTER. This highlights the channel for editing  
purposes but does not make it active. The channel can also be  
highlighted with the arrow keys.  
3. Press MODE. This brings up a submenu for editing (this is a toggle  
key. Pressing MODE again removes the submenu).  
4. Use the up/down arrow keys to select EDIT and press ENTER.  
5. The NAME field should be highlighted. If not, use the left/right arrow

4.1.3. Factory-Preset Channels and Sources  
Some channels have factory-preset source files, which the operator can  
select one (1) of for faster setup. These preset source files should be  
checked for proper timing, geometry, and convergence and readjusted, if  
necessary. The following table indicates the factory-preset sources  
attached to Channel 1:

4.1.4. Internal Source  
Every channel has a preset internal source shown as SOURCE 0 on the  
SOURCE list. This is factory set default timingfor the projector with  
scanning rates of 33.3 kHz (horizontal) and 59.3 Hz (vertical). This  
internal source is used to read menus when there is no source input  
connected to the projector. To use this internal source, select CHANNEL 0,  
then press ENTER. This internal source can be copied to any other  
channel but it cannot be cut, edited, or pasted to.  
4.2. Timing Settings and Adjustments  
Each type of source requires timing settings and adjustments. Perform these prior  
to geometry because the geometry adjustments are dependent on the proper  
timing of raster scanning. The Timing adjustments are universal to 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;  
TL (Tri-Level) which is used mainly for HDTV.  
To set the Clamp Type:  
1. Access the TIMING menu.  
2. Press #4, CLAMP TYPE from the TIMING menu.  
3. Highlight BP, ST, or TL using arrow keys.  
4. Press ENTER to select.  
NOTE: WVHS and HDTV use tri-level sync signals. When the HDTV  
VIC is used, the clamp type should be Tri-level.”  
4.2.2. VTR Mode  
Set VTR mode to ON position if the projectors input comes from a VTR  
source or is line-doubled DVD. This setting stabilizes the VTR sync input.  
Otherwise, set the VTR mode to OFF.  
To set the VTR Mode:  
1. Select VTR MODE from the TIMING menu.  
2. Press ENTER to toggle the VTR MODE to OFF (unchecked box)  
unless using a VTR as a video source.  
3. Press ESCAPE to return to the TIMING menu.

NOTE: Blanking, Phase, Size, and Centering are functions that  
contribute to the entire image. If one (1) function is adjusted,  
the others need to be rechecked and readjusted, if necessary.  
4.2.4. Phase  
The Phase adjustment positions the image within the raster.  
To adjust Phase:  
1. Use external image.  
2. Select PHASE from the TIMING menu.  
3. Use the arrow keys and adjust the horizontal and vertical phase so  
that the image folds over on either side or at the top and bottom.  
Center the image on the raster (see Figure 4.0-3 on page 4-12).  
NOTE: Overadjusting vertical phase may cause vertical retrace lines  
to appear in the image.

4.3. Geometric Adjustments  
Geometric adjustments are performed for each type of source. Timing settings  
must be completed before geometry can be performed correctly.  
NOTE: Toggle the REG ENABLE box to the unchecked mode in the GEOMETRY  
menu. This ensures that any previous convergence corrections will not influence  
the Geometry adjustments  
4.3.1. Centering (G)  
Centering moves the position of the raster on the CRT without wrapping  
around.  
To Center (Green):  
1. Use an external image.  
2. Select CENTERING from the GEOMETRY MENU.  
3. Use the HIDE key and hide R and B (toggle the RGB KEY to select R  
only and press HIDE then toggle the RGB KEY to select B only and

5. Use the arrow keys and position the Green raster vertically and  
horizontally so that it is centered on the screen (refer to Figure 4.0-3  
on page 4-12).  
6. Recheck PHASE and BLANKING and readjust, if necessary.  
7. Press ESCAPE or ENTER to exit.  
4.3.2. Size  
The size adjustment fits the size of the image to the screen size within  
the limits of the ILA® and CRT.  
To adjust Size:  
1. Continue with an external image.  
2. Select SIZE from the GEOMETRY MENU.  
3. Use the arrow keys and adjust the size of the image to the screen  
horizontally and vertically (refer to Figure 4.0-3).  
NOTE: Select RGB (all) for coarse SIZE ADJUSTMENT. Select R or B for  
fine adjustment of R and B with reference to G.  
4. Recheck and readjust centering, phase, and blanking, if necessary, to  
keep the entire picture in the center of the screen.  
NOTE: Make the picture slightly smaller than the screen size.  
This makes other geometric adjustments easier. After completing  
geometric adjustments, slightly readjust size, if necessary.  
5. Press ESCAPE or ENTER to exit.

4.3.3. Bow  
NOTE: Skip this procedure if the vertical centerline is straight and the  
horizontal centerline is level (refer to Figure 4.0-5 Bow Distortion on page 4-  
14).  
With bow distortion, the picture bends in the same direction on the edges  
and in the center of the test pattern. This means that the vertical or  
horizontal centerline is bowed in one (1) direction causing the entire  
pattern to bend in that same direction (refer to Figure 4.0-5 on page 4-  
14). Use the Standard Crosshatch test pattern to spot Bow distortion.  
To correct for Bow Distortion:  
1. Select the Standard Crosshatch test pattern.  
2. Select BOW from the GEOMETRY MENU.  
3. Use the up/down arrow keys to correct for vertical bow distortion.

4.3.4. Skew/Rotate (G)  
Skew and Rotate are corrected in the same procedure using the same  
screen patterns. Skew distortion leanshorizontally like a trapezoidal  
pattern. This means the vertical centerline is skewed in one (1) direction  
or another causing the entire pattern 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 pattern (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 Skew setting is  
correct (as described in Section 4.3.7 on page 4-18) and should not be  
changed.  
Perform the Rotate procedure first to make the horizontal lines horizontal.  
If the pattern leans left or right (as illustrated in Figure 4.0-7 on page 4-  
15) proceed with the Skew procedure to correct.

4.4. CRT Focus and H/V Dynamic Focus  
The CRT and H/V Focus adjustments are factory-set and do not normally require  
adjustment. They should be performed together in a back-and-forth manner to  
achieve the best possible overall focus.  
To perform the CRT Focus:  
1. From the FACTORY ADJUSTMENTS MENU, select CRT FOCUS.  
2. Select G on the remote.  
3. Select the STANDARD CROSSHATCH test pattern.  
4. Use the up/down arrow keys to obtain the best possible focus in both the  
center of the screen and in the overall test pattern.  
5. Repeat the above steps for R and B.  
To perform the H/V Dynamic Focus:  
1. From the FACTORY ADJUSTMENTS MENU, select H/V DYNAMIC FOCUS.  
2. Continue with the STANDARD CROSSHATCH test pattern from above.  
NOTE: The H/V Dynamic focus is performed on all three (3) colors together  
and the colors are not individually selectable.  
3. Use the up/down arrow keys to achieve the best possible focus at the edges  
of the screen.  
4. Repeat the CRT Focusing from above, then repeat the H/V Dynamic Focus  
again. Several iterations may be needed to achieve the best possible overall  
screen focus.  
4.5. ILA® Sensitivity and Bias  
ILA® Sensitivity and Bias are preset for the factory-set sources and will not  
normally require adjustment. Readjustments may be required due to variations  
between the factory and the field environments. When new sources are set up,  
ILA® Sensitivity and Bias must be set (or copied from another source and  
touched-up) for each new source.  
The ILA® Sensitivity and Bias can be adjusted for any color. It is preferable to  
start with Blue since Blue is a weaker color to observe than Red or Green. The  
ILA® Sensitivity is the ILA® biasing frequency that affects the resolution and  
brightness on the screen. The ILA® bias settings adjust the electrical bias levels  
to each ILA® assembly to a just offthreshold point. The smallest incoming light  
from the CRT will cause the ILA® assembly to react. When properly set, this  
adjustment will put each ILA® assembly at the threshold of operation. If set  
incorrectly, the black level will be adversely affected and the ILA® assembly will  
not react properly to incoming light. Perform all ILA® Bias adjustments in a  
darkened room.

box is checked.  
2. Use the HIDE KEY and hide Red and Green.  
3. Toggle the RGB KEY to highlight Blue.  
4. Access ILA® SENSITIVITY ADJUST from the MAINTENANCE MENU.  
5. Use the up/down arrow keys to select an ILA® Sensitivity of 11 as indicated  
in the screen window. This is the default setting and should be acceptable  
for general viewing. A lower number may be preferred for HDTV. A higher  
setting results in higher brightness but greater image lag and possibly lower  
resolution. The ILA® Sensitivity setting depends on the type of viewing  
environment. Some trial and error may be needed to get the exact setting for  
each environment.  
6. Press ESCAPE when the setting is complete.  
NOTE: Computer graphics require high resolution but typically are not fast  
movingthe ILA® Sensitivity will typically by set in the range of 11 - 15.  
Video sources are typically lower resolution but have more movementthe  
ILA® Sensitivity is set in the range of 8 - 11.  
Changing ILA® Sensitivity requires re-  
checking and re-adjusting, if necessary, sensitivity offset, threshold  
offset, and shading.  
CAUTION!!!  
To set the ILA® Bias:  
1. Use the same color from the ILA® Sensitivity adjustment  
and with the same two (2) colors hidden.  
2. Uncheck SHUTTERS ON HIDE. Hide the selected color.  
3. Access ILA® BIAS ADJUST from the MAINTENANCE MENU.  
Use the up/down arrow keys to decrease the ILA® Bias so the brightest area  
of the ILA® image just extinguishes. Then increase the bias level until the  
ILA® image just begins to appear on the screen.  
NOTE: It is crucial to set the bias level so the selected color just begins to  
appear on the screen. Find the spot on the screen where the selected color  
first begins to get brighter and use that as the reference point. Adjust the  
bias level above and below this point to find the setting where one (1) click  
causes an increase in brightness and stop at that point. This insures that the  
weakest signal will cause the ILA® assembly to respond properly.  
Repeat the above ILA® Sensitivity and ILA® Bias procedures for the remaining  
two (2) colors. Save the changes.

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 time  
now to read the entire Convergence (XY Registration) section before making any  
adjustments.  
4.6.1. Purpose of Convergence  
The XY Convergence adjustments are used to converge or overlay the  
Red, Green and Blue CRT images over the entire 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) different cursor modes (as described in Table 4.0-3) are used  
to make adjustments.  
Table 4.0-3 Cursor Modes  
Cursor Mode  
Description  
Moves the cursor around the screen.  
Increases or decreases the cursor size.  
Makes the actual convergence adjustments.  
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 the area. Use the cursor  
size that best fits the area. Some areas may be satisfactory and will not  
need any convergence corrections.  
The greatest convergence corrections are made at the center of the  
cursoravoid making corrections at the edges of the cursor. Move the  
center of the cursor over the area that needs correcting. A cursor with a  
long centerline is affected equally all along its centerline by the  
adjustments.

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 4.0-  
12 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 sequence  
shown.  
3. Size down to a ¼ screen cursor size. Move down and across the  
screen in the sequence shown in Figure 4.0-13in 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 rectangles.  
Use the same general pattern as with the previous cursors.  
Before beginning adjustments, experiment with the different cursors in  
SIZE or MOVE MODES.  
If the ADJUST MODE cursor is displayed  
CAUTION!!!  
(illustrated in Figure 4.0-14 on page 4-27), pressing the arrow keys will  
alter the convergence settings. Experiment with the arrow keys only when  
in the MOVE or SIZE MODES, not while in the ADJUST MODE.  
To adjust by Size or Move Convergence:  
1. Access Registration from the Convergence menu.  
2. Press Mode to change cursor type.  
3. Use the arrow keys to see the various cursor sizes in Size mode.  
4. Use the arrow keys to move the cursor around the screen In Move  
mode.

4.7. Black Level (G2) and Sensitivity Offset  
G2 sets the threshold of the CRT image and is adjusted, along with the Sensitivity  
Offset adjustment, using the Grey/Pluge test pattern. Together, these  
adjustments determine the level of the darkest and brightest areas of the video  
image.  
The G2 adjustment is preset at the factory and may need little or no adjustment.  
These adjustments are made in sequence, one (1) color at a time. It is preferable  
to start with Blue because it is the weakest color of the three (3) to observe.  
When the Blue settings are complete, the same adjustments are performed for  
Green and Red.

4.8.3. Color Balance (Grey Scale)  
Color balancing sets the color balance over the entire screen. This adjustment  
may be necessary after performing Threshold and Sensitivity procedures. The  
Grey Scale test pattern should be grey throughout the entire screen area with a  
normal, gradual brightness transition from bar to bar (no perceived coloration).  
If the test pattern is not grey throughout, color balancing is necessary.  
Threshold and Sensitivity Offsets can be made for the entire screen to get proper  
color balance for the bright and dark areas.  
To check for proper Color Balance (Grey Scale):  
1. Access GREY SCALE from the TEST PATTERN MENU.  
2. Toggle the RGB KEY and verify all colors are selected and on screen.  
3. Observe the two or three darkest bars in each of the four (4) sections  
of the test pattern. If any color is too prominent in these two or three  
bars, adjust the Threshold Offset (see instructions following for  
adjusting the Threshold Offset) for that color.  
4. Observe the two or three brightest bars in each of the four (4)  
sections of the test pattern (refer to Figure 4.0-17 on page 4-31).  
If any color is too prominent in these two (2) or three (3) bars, adjust  
the Sensitivity Offset (see instructions following for adjusting the  
Sensitivity Offset) for that color.  
NOTE: A color may appear too weak, due to the other two (2) colors  
being too dominant. If so, slightly increase sensitivity offset for the  
weak color.  
To adjust the Sensitivity Offset for the best Color Balance:  
1. Toggle the RGB KEY and select the color that is too prominent in the  
brightest bars .  
2. Access SENSITIVITY OFFSET from the CONVERGENCE MENU.  
3. Use the up/down arrow keys to increase or decrease the Sensitivity  
Offset slightly so that the brightest bars in the test pattern are without  
color, i.e. grey. Make a note of the offset data number before making  
any adjustments in case an error is made and the original setting is  
needed. Recheck the test pattern for a normal, gradual transition from  
bar to bar. If increasing the Offset, avoid overadjusting any of the  
colors. Leave a normal, gradual brightness transition between the  
two (2) brightest bars.  
NOTE: The two (2) numbers that appear in the box on the screen  
represent the lowest and highest Sensitivity settings on the screen. If  
either of these settings is at the minimum (0) or maximum (255) there  
will be no adjustment range available to adjust the Offset. This means  
that one (1) area on the screen has been adjusted too high or too low  
during the Sensitivity adjustment and is restricting the Offset  
adjustment.  
Before the Offset can be adjusted, this area must be increased or  
decreased to allow for more range to perform the Offset adjustment.

narrows the video bandwidth. Use trial and error to determine if this  
VNR option is appropriate for the image being viewed.

4.10. Backing up Settings  
The source file parameters previously set up (and any other source files attached  
to one channel) can be copied to another channel. Copy parameters if the source  
has the same basic parameters but different picture settings. A channel can be  
set up for a source with picture settings specific to that source, then copied to  
another channel. The channel receiving the copied information can have the  
picture settings adjusted for the image that will be received on that channeltwo  
(2) channels are now set up for the same type of source but with different picture  
settings. This function saves time and also backs up the settings from the original  
channel. When copying from one (1) channel to another channel, verify that both  
channels use the same type of VIC. This can be determined by accessing the  
SYSTEM-MAINTENANCE MENU and selecting STATUS LIST, which shows the VIC  
types.  
To Copy Settings from one channel to another channel:  
1. Access the CHANNELS MENU and highlight the channel that is to be copied  
(highlight by pressing the number or scroll with arrow).  
2. Press MODE on the remote.  
3. Select COPY from the submenu. This copies the channelsname, VIC path,  
and attached sources into a Paste Buffer.  
4. Highlight the channel to PASTE TO; press MODE, select PASTE.  
Verify that the channel copied to is blank.  
CAUTION!!!  
5. If all of the sources that were copied from the first channel are not needed in  
the second channel, they can be detached from the second channel.  
Change to the SOURCE LIST, then select the unwanted sources with the  
arrow keys, then deselect by pressing ENTER to detach them from the  
channel.  
6. These copiedchannels can be adjusted for Picture and Timing to match  
any incoming source for the new channel without affecting the original  
source from the first channel. Gemometry, Conversion, and ILA® Setting are  
sharedby the Source File.  
NOTE: For convenience store a list of all available sources in one specific  
channel. This can be used as a source masterlist. For example, have all  
available sources attached to Channel 99. Use this as a master list from  
which any source can be attached at any time. Having all available sources  
in one masterchannel avoids having to remember where any specific  
source is located and the time involved in hunting through various channels  
to find a particular source.

The HJT Model 100 Projector is designed and built to provide years of trouble-free  
servicehowever, some periodic maintenance is necessary to keep the projector  
operating at an optimal level.  
Use Hughes-JVC Authorized Service only. This protects your equipment  
and keeps its warranty in force.  
When performing any maintenance, protect yourself and the equipment by  
following these guidelines:  
Turn the projector off and disconnect the power cord.  
Observe all Caution and Warnings.  
Allow a discharge time of at least one minute for the high voltage to bleed off  
before removing the power plug.  
Do not turn off the circuit breaker at the rear of the projector until the arc lamp  
cooling fans have automatically stopped running.  
5.1. Preventive Maintenance  
Avoid direct sunlight, moisture, heat and improper mounting.  
Avoid using in a dusty environment.  
Provide sufficient ventilation to the fans to avoid overheating of internal  
components.  
Do not place magnetic equipment near the projector.  
Disconnect AC power from the projector before cleaning.  
5.1.1. Cleaning the Cabinet  
Clean the cabinet periodically with a soft cloth. If the cabinet is heavily  
stained, use a mild detergent solution. Never use strong detergents or  
solvents such as alcohol or thinner to clean any part of the projector.

Chapter 5Preventive Maintenance  
5.1.2. Cleaning the Projector Lens  
Under normal environmental circumstances, clean lenses only when  
accumulated dust makes the picture fuzzy. Clean the projection lenses  
with a camel hair brush to remove dust or use dry air to blow dust off.  
Dampen a lint free cloth with lens cleaning fluid (do not use window  
cleaner or alcohol) and wipe the lens clean in a continuous circular  
pattern from the center of the lens to the edge.  
Only clean lens when absolutely necessarytoo frequent cleaning can  
destroy the lens coating.  
5.1.3. Air Filters  
Periodically inspect the air filters at the bottom and rear of the HJT Model  
100 Projector for heavy accumulation of dirt and debris that may inhibit  
proper air circulation. The air filters can be cleaned with air guns, or  
submerged into a mild soap bath, being careful to thoroughly dry the filter  
before use.

Appendix A. Extron Switcher Interface to Model 100  
This appendix provides instructions on how to set up and configure the HJT Model 100  
Projector for proper operation with Extron Switchers 10+, 8, and 4LD.  
The baud rate for the Extron switchers is 19200. Since Port A is locked to a baud rate of  
9600, Port B should be used for Extron Switchers. The projector port assignment must  
be selected and the VIC channel assignment must be edited for a switcher.  
To select the Baud Rate:  
1. From the MAIN MENU, select #7, SYSTEM, then #4, COMM. SETUP.  
2. From the COMM. SETUP menu, select PORT B SPEED.  
3. From the SPEED SELECTION LIST, select 19200.  
4. Press ESCAPE to go back to the COMM. SETUP level.  
To set the projector port assignment:  
1. From the COMM. SETUP menu, select PORT B DEVICE.  
2. From the DEVICE TYPE list, select #3, VIDEO SWITCHER.  
3. Turn power OFF at the remote control.  
4. Wait until the Arc Lamp fans have stopped running, and provide a system  
cold bootby toggling the circuit breaker on the projector rear panel to OFF,  
then back to ON.  
To edit the VIC channel assignment (refer to Section 4.11 on page 4-39  
for more information on editing):  
1. From the CHANNELS list, select the channel to assign the switcher.  
2. Press MODE. This is a toggle key that brings up a submenu for editing  
(pressing MODE again removes the submenu.)  
3. Select EDIT from the submenu and press ENTER.  
4. Use the right arrow key to toggle over to the third VIC column.  
5. Press ENTER and use the up/down arrow keys to select the current switcher  
channel number. Press ENTER when the current switcher channel number is  
shown.  
6. Press ESCAPE to exit the EDIT MODE.  
A.1 Extron Switcher Configuration  
The Extron switcher must have two (2) important parameters for it to work  
optimally. First, it must be in the Mastermode. If in Slavemode, the display  
power and video mute buttons are internally inhibited. Second, it must receive a  
projector Power Onmessage. This message is sent routinely during a projector  
Power Onsequence. If the Power Onmessage is not received due to cabling  
problems, baud rate problems, projector configuration, or switcher emulation  
problems, the video mute will not work properly.

Appendix A-1  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Appendix AExtron Switcher Interface to Model 100  
In addition, all Extron switchers must be configured to use HJT protocols and  
19200 baud rate (Hughes-JVC emulation). This is usually done at Extron and a  
Configured for Hughes-JVCsticker is placed on the back of the unit. The Extron  
Service Manual for each unit describes how to reset the system to a state  
compatible with the HJT protocol, if necessary.  
A.2 Extron Users Manual Inaccuracies  
Early revisions (up to Rev C) of the Extron Model 8 and 10 Users Manual,  
describe incorrect configuration procedures for setting Master mode. Specifically,  
the description shows that when switch 4 of the address switch block is set to the  
closed position it enables the configuration mode. The correct position for this  
switch is the opened position. A correct example for setting the Model 8 and 10  
switchers is detailed below.  
A.3 Key Operational Differences Between Models  
The switcher firmware for Model 8 and 10+ function differently from the Model 4  
firmware. Switching on the Model 8 and 10+ always occurs independently of the  
projector. For example, when a channel switch is pressed on the Model 8 and  
10+, the switcher automatically selects that channel after a short time period (~2  
seconds). This channel switching occurs even if a projector is not connected to a  
switcher. When a projector is connected to a Model 8 or 10+ (and the  
communication interface is working properly) and a channel switch is pressed, the  
projector normally changes the channel immediately (before the 2-second time  
period has expired).  
On the Model 4LD, there is no automatic channel switching. Channel switching is  
prohibited unless commanded by the projector. If the communication interface  
between the switcher and projector is not functioning properly, no channel  
switching occurs.  
A.3.1 Switcher to Projector Configuration Example  
The following provides an example of how to configure an Extron Model 8  
Switcher to a HJT Model 100 Projector:  
1. Connect the switcher to the Model 100, Port B.  
2. Set Comm. Setup to Port B.  
3. Set the Port B baud rate to 19200.  
4. Turn power off at the remote control (or PC).  
5. Wait at least one (1) minute, for the system to reach an Offstate  
from Step 4, then toggle the circuit breaker on the rear panel to Off  
and then back to On.  
6. Verify that the Model 8 Switcher internal dip switches are set to  
Hughes Emulation and the baud rate is set to 19200  
(use the Extron manual to confirm this).  
7. Turn power on to the Model 8 Switcher.  
8. Set the Model 8 external addressdip switch #4 to the open position.

9. Set the Model 8 external addressdip switch #5 to the closed  
position.  
10. Wait 10 seconds.  
11. Set Model 8 external addressdip switch #4 to the closed position.  
12. Turn power on at the remote control.  
13. Edit the Model 100 VIC channel assignment.  
NOTE: Steps 8 and 11 are incorrectly stated in early versions  
(Rev C or earlier) of the Extron System 8 and 10 Users Manual.  
The correct steps are shown above.  
A.3.2 Failure Diagnostics  
If the channel change, video mute and power buttons on the switcher ALL  
do not work properly, check the cabling, baud rate, or emulation. This is  
an indication that data is not being sent properly between the switcher  
and the projector.  
If the channel change buttons work, but the video mute and power  
buttons do not, check the switcher master mode setting. This is an  
indication that the switcher is in slave mode.  
If the channel change and power buttons work, but the video mute button  
does not work, turn power off on the remote (or PC), wait until the Arc  
Lamp fans have stopped running, then toggle the projector circuit to Off.  
This problem is an indication that the switcher did not receive the  
projector Power Oncommand.

Appendix BConfiguration Data  
Export / Import Procedures (Rev 1.0.0)  
HJT Model 100 Projector Appendix B defines the steps to perform a Configuration Data  
Export and Import from the projector to a host computer. The host computer can be any  
system that has RS232 download and upload capability, including an IBM-PC  
compatible, an Apple MacIntosh, or a UNIX systemthe following procedures are for an  
IBM-PC running the WINDOWS 3.1 OS. We will use the WINDOWS TERMINAL application  
for communication with the projector. Other terminal emulation programs can be used  
(i.e.: PROCOMM) but all testing has been done with the TERMINAL application.  
Appendix B Note 1  
The TERMINAL application setup is the same as for controlling the projector via an  
ANSI TERMINAL (refer to HJT Model 100 Projector Users Guide, Chapter 3)  
Appendix B Note 2  
Export/Import can be performed on either Port A or Port B. The Port must be  
configured for ANSI TERMINAL.  
Port A speed is determined by Dip Switch #4 on the System Controller  
board. ON is 9600 baud, OFF is 19200 Baud.  
Port B can be configured for 2400, 9600 (default), or 19200 through the  
COMM SETUP MENU.  
If both Port A and Port B are ANSI TERMINALS, use Port A for Export/Import,  
by setting Port A device = None, or Switcher, or Tethered Remote,  
and set Port B Device = ANSI.  
Remember to POWER OFF (CONTROL + P) and HW RESET (circuit breakeron  
rear panel) after changing any configuration parameters, OR POWER OFF, then  
press CONTROL + SHIFT + ^ to reset.  
Your computer must have a 16550 UART  
WARNING!  
installed on the COMM PORT TO use 19200 Bauduse 9600 Baud if you  
are not sure. An unbuffered 8550 UART will lose data during EXPORT,  
which cannot be detected until a later IMPORT is attempted. With either  
Baud, always use SOFTWARE FLOW CONTROL (XON/XOFF).

Raster  
The area illuminated by the scan lines on a CRT.  
Resolution  
The degree of sharpness of a displayed or printed  
character or image; the amount of detail in a picture. On  
a display screen, resolution is expressed as the number  
of horizontal dots (columns) by the number of vertical  
lines (rows). For example, a 680 x 400 resolution means

Sensitivity (White)  
Adjustment for decreasing brightness on the bright areas  
of the screen. Used with Threshold adjustment to obtain  
optimal projected image.  
Sharpness  
Apparent image resolution. High sharpness may be the  
result of high resolution, or it might be an optical illusion  
caused by image enhancement or by visible edges in a  
display, such as the vertical stripes of an aperture grille  
CRT.  
Size Adjustment  
Skew  
Fits the size of the projected image to the screen size.  
Distortion caused by the vertical or horizontal centerline  
not being exactly vertical or horizontal resulting in an  
image that leansright/left or up/down.  
Source  
A specific video/graphic input format such as VGA,  
HDTV, NTSC etc. with a given set of parameters such as  
horizontal and vertical scanning rates,  
interlaced/noninterlaced scanning, and sync  
source/polarity.  
Source File  
A memory location used to store Geometry,  
convergence, Shading and ILA® settings setup data for  
a specific video/graphic sources.  
Synchronization  
Also called "sync" for short. Working together, horizontal  
and vertical sync signals from the signal source control  
the monitor's scan circuits to properly time the lines and  
frames of a picture.  
Threshold (Black)  
Adjustment for increasing brightness on the dark  
areas of the screen. Used with Sensitivity adjustment to  
obtain optimal projected image.  
Throw  
Distance to the screen from the projector.  
Variable Flat Field  
Test Pattern #5. Used for Threshold, Sensitivity and  
shading purposes.  
Vertical Resolution  
The amount of detail that can be perceived in the vertical  
direction; the maximum number of alternating white and  
black horizontal lines that can be counted from the top of  
the picture to the bottom.  
Vertical Scan Frequency  
Input signal vertical scan frequency.  
Vertical Scan  
Reversal Jumpers  
Reverses the image vertically for use with ceiling  
displays or mirror-bounced displays. Information on
