Vidikron Vision Model 90t and Model 100t Owner’s Operating Manual 41 
Remote Control: The Remote Control menu shows you the primary and secondary infrared 
(IR) codes to which the Vision 90t/100t will respond. By default, both are set to 17. You can 
change these codes if either:
 Another device in the theater (a DVD player, for example) is responding to commands 
from the Vision 90t/100t remote control in ways that are unpredictable or undesirable. 
 You have multiple Vision 90t/100t projectors and want to control them independently, as 
opposed to broadcasting commands from a single remote to all of them. In this scenario, 
you can use multiple remotes programmed to use different IR codes. Or, you can use a 
single remote and change the IR code as needed to address a specific projector.
When you change a remote code on the Vision 90t/100t, you must re-program your remote 
control to send that same code. To do this:
1. Using a straightened paper clip or similar object, press and hold the 
CODE button on the remote control for approximately three seconds, 
or until the red LED on the remote lights solid red.
2. Enter a new two-digit code between 00 and 31 inclusive. Use the ANA 
button for “9” and the 4x3 button for “0.” Include a leading zero for 
single-digit codes; for example, enter 9 as “09.”
3. The LED turns off to confirm the code change. If you enter an invalid code, the LED 
flashes for three or four seconds. Try again, entering a valid code. 
Display Device: The options in the Display Device menu allow you to change the picture 
orientation, reset the lamp timer, perform lens adjustments and access additional test 
patterns. 
• Installation: Select Installation from the Display Device menu to change the picture 
orientation to suit the method of installation (Floor Front, Floor Rear, Ceiling Front or 
Ceiling Rear). 
This menu page also displays the number of hours that the lamp has been in service, and 
lets you reset the counter (which is recommended after you replace the lamp; refer to 
Lamp Replacement on page 45). 
•Lens: Select Lens from the Display Device menu to access the motorized lens controls. 
Refer to 
Lens Adjustments on page 28. 
•Diagnostics: Select Diagnostics from the Service menu to access additional test patterns 
for calibration or measurement purposes:
 Select Red, Green or Blue to display only the selected color (simulating a filter of that 
color). 
 Select 75 or 100 to display color bars (75 IRE or 100 IRE). 
 Select Horz or Ver t to display a horizontal or vertical gray ramp. 
 Select Checks to display a 15-segment checkerboard pattern. 
 Select Align to display a white grid against a black background (useful for verifying 
proper image or screen alignment). 
Use the rear-panel keypad to change a projector IR code. Then, change the 
code sent by the remote to match as described below. 
Do not change the “Type” setting in this menu.

HD Format: If the characteristics of the incoming signal on the HD1 or HD2 inputs are 
known, select HD Format from the Service menu and set them as described below. Doing so 
can reduce the time it takes the Vision 90t/100t to switch from HD to 480i signals or vice 
versa. 
This is generally not necessary unless the Vision 90t/100t – for whatever reason – has 
difficulty determining the color space (RGB or YUV), bandwidth or resolution of the incoming 
HD signal. In most situations, the Auto settings work well. 
• HD/RGB 1 and HD/RGB 2 (Color Space): Select Auto, RGB or YUV.
• ADC Bandwidth: Select Auto, 75 MHz, 150 MHz or 300 MHz.
• YPbPr Input Resolution: Select Auto or specify the input resolution, if known: 480i, 480p, 
576i, 576p, 720p or 1080i. 
Triggers: Select Triggers from the Service menu to configure the 12-volt trigger outputs. You 
can assign one or more trigger outputs to each aspect ratio. Those triggers are then activated 
by selecting that aspect ratio. 
If your projector is equipped with the Vidikron CineWide with AutoScope system, assign at 
least one trigger output (the same one to which the lens motor is connected) to the Cinema 
and IntelliWide 2.35 aspect ratios.
To save the trigger settings so that they can be restored after a System Reset (described 
below), press 
 repeatedly to highlight “Save.” Then, press ENTER. 
Miscellaneous: Select Miscellaneous from the Service menu to set the following options: 
• Language: Select Language from the Miscellaneous menu and press the up- or 
down-arrows to select the OSD language. (Currently, only English is supported.) 
•Menu Mode: This is the manner in which the OSD menus appear and disappear when you 
press MENU. Choose one of the following: 
0 = No transition; menus abruptly appear and disappear.  
1 = Menus fade in and out.  
2 = “Checkerboard” dissolve; menus appear and disappear in sections.  
3 = “Window shade” effect; menus are drawn on a diagonal from top left to bottom right, 
and retract in the opposite direction. 
• Timeout - Short/Long: These settings control how long the OSD menus stay on screen. 
Select a time-out period of from 2 to 60 seconds. 
• Side Bar Color: This controls the color of the inactive image area. The range is from -100 
(black) to 100 (white). 
 
 
The inactive image area is on either side of the active image area when using the Standard 
4:3 aspect ratio, and above and below the active image area when using the Letterbox 
aspect ratio. 
•Film Mode: Enable Film Mode to smooth out moving images from interlaced, 
standard-definition (SD) sources. In most cases, the Vision 90t/100t detects the proper 
“pull-down” rate and vertical frequency. However, if your source is jittery and/or tearing 
you may wish to enable Film Mode to ensure stable processing for that source.

Resolution: The Vision 90t/100t defaults to an output resolution of 720p. When using the 
Vision 90t/100t with a computer or certain HD sources, you may want to force it to use a 
different output resolution. If so, select Resolution from the Service menu and choose one. 
Then, press ENTER to confirm. 
System Reset: To reset ALL projector and controller settings (including image settings) back 
to their factory defaults, choose System Reset from the Service menu. 
A confirmation message appears, reminding you to save your settings before you perform 
the reset, so that you can restore them afterwards. If you have done this, select Confirm to 
continue with the reset. Otherwise, click Back to cancel. 
 
Restore Saved Settings: Following a System Reset, select Restore Saved Settings to apply all 
previously-saved settings to the projector.
This action is not undoable. Proceed with caution! Before you perform a 
System Reset, save ALL settings, including “Custom” ISF Presets (
page 37), ISF 
Day/Night presets (page 39), Output Shift settings (page 39), Input Names 
(page 40) and Trigger settings (page 42).

Troubleshooting Tips
Table 5-1 provides some general guidelines for troubleshooting problems you may 
encounter with the Vision 90t/100t. 
If you encounter an issue not described here or in Section 3 (refer to Installation 
Considerations on page 15), or if the suggested solutions fail to resolve the problem, please 
contact your Vidikron dealer or Vidikron Technical Support. 
Table 5-1. Troubleshooting Chart 
SymptomPossible Cause(s)Solution
The projector does not turn on 
after initial installation. The 
power LED lights red after you 
press the power button.  The Vision 90t/100t is not 
plugged in or the AC outlet 
is not active.  Ensure that the Vision 
90t/100t is plugged in and 
that the AC outlet is active. 
The projector is on, but there is 
no video image on-screen.  Incorrect source selection. 
 Source component is not 
turned on. 
 Select the correct source. 
 Turn on the source. 
A projected image from a DVD 
is split or otherwise scrambled. DVD player is set to 
progressive scan mode.  Turn off progressive scan 
on the DVD player. 
 Connect the DVD player to 
the HD/RGB 1 or HD/RGB
 2 
input. 
Image is too bright and/or 
lacks definition in the bright 
areas of the image.  Contrast is set too high.  Lower the contrast setting. 
Image appears “washed out” 
and/or dark areas appear too 
bright.  Brightness is set too high.  Lower the brightness 
setting. 
Colors in the image are 
swapped; for example, reds 
appear blue or vice versa.  The Red/Pr, Green/Y or 
Blue/Pb outputs from the 
source are connected to the 
wrong inputs on the Vision 
90t/100t.  Ensure that the source 
outputs are connected to 
the correct Vision 90t/100t 
input. 
Image geometry is incorrect. Incorrect aspect ratio 
selection.  Select the aspect ratio that 
best matches the source 
image and screen size (refer 
to 
Table 4-1). 
The projector will not turn 
back on after it was powered 
down, or the image disappears 
during operation.  The projector will not turn 
on for two minutes after 
power-down, to protect the 
lamp. 
 The lamp has failed. 
 Wait two minutes until the 
LED at the front of the 
Vision 90t/100t turns red.

6.1 
RS-232 Connection and 
Port Configuration
To interface the Vision 90t/100t with a home theater automation/control system or a PC 
running terminal emulation software, connect it to your control system or PC as shown in 
Figure 3-10. 
Configure the RS-232 controller or PC serial port as follows: no parity, 8 data bits, 1 stop bit 
and no flow control. Set the baud rate to 19200, to match that of the Vision 90t/100t RS-232 
port. 
6.2 
Serial Command Syntax
Serial commands to the Vision 90t/100t take the following form:
 Commands are not case-sensitive. 
 For a single command that takes no parameters, type the command followed by a 
carriage return; for example, to set the aspect ratio to Letterbox, type 
LETTERBOX
 . 
 For a single command that takes a parameter, type the command, a space or a comma 
and the desired value followed by a carriage return; for example, to set the brightness to 
-10, type BRIGHTNESS
 -10  or BRIGHTNESS,-10 . 
 You can also send a string of multiple commands on a single line, separated by commas. 
For example, COMPOSITE,BRIGHTNESS
 100,ANAMORPHIC  switches to 
the Composite video input, sets the brightness to 100 and sets the aspect ratio to 
Anamorphic. Command strings can be up to 255 characters long. 
 
Table 6-1 lists the RS-232 command set. The “Parameter (min/max)” column shows the valid 
parameter ranges, or “NA” for commands that take no parameters. 
When you enter a valid command, the Vision 90t/100t executes it and acknowledges it with a 
plus sign on the command line (+ >). When you enter an invalid command – one that is 
misspelled or followed by values outside the valid range for that command – the Vision 
90t/100t ignores it and returns a minus sign (- >). 
6Serial Communications
Avoid combining the ON or POWER 1 commands with other commands on a 
single line. After sending ON or POWER 1, allow at least 15 seconds for the 
projector to power up. Once it does, it will accept and properly execute 
multiple serial commands.
