RGB 201 Rxi Universal Interface • Installation and Operation
When a centering control reaches its minimum or maximum
limit, the LCD displays MIN or MAX on the line below H-SHIFT
or V-SHIFT.
Once the centering controls are no longer active, the centering
settings are saved, and the LCD displays the current scan rates.
If DIP switch 1 (DDSP) on the rear panel is set to On (right) and
a centering control is rotated, the LCD displays N/A DDSP ON,
and the image does not shift on screen.
Troubleshooting
Turn on the input device (computer, audio device) and output
device(s) (projector, monitors, speakers) and plug in the
interface’s AC power cord. The image should now appear on
the screen, and sound should be audible.
If the image does not appear or there is no sound
1. Ensure that all devices are plugged in.
2. Make sure that each device is receiving power. The
interface’s front panel LED lights if the interface is
receiving power and an active sync signal.
3. Check the cabling and the audio connector wiring and
grounding, and make adjustments as needed.
4. For digital display devices (including LCD, DLP and
plasma devices), try turning DIP switch 1 (DDSP) On (up)
or Off (down) on the rear panel.
5. To test the system setup and output, substitute a stand-
alone video test generator (VTG) for the computer input.
Unplug the power cords to the input and output devices
and the interface, replace the video source with a VTG,
then reconnect power cords to restore AC power.
6. Call the Extron S

Sales & Technical Support Hotline if
needed.
If the image is not displayed correctly
1. If the output image looks too green, the sync on green
(SOG) DIP switch (switch 2) may be set to On (up), and
the display device may not be congured to handle SOG
signals. Set the switch to Off (down).
2. If the picture bends or ags at the top of the screen, set the
serration pulse DIP switch (switch 3) to Off (down).
3. For a display device that experiences intermittent glitches,
try turning DDSP On (up) or Off (down) using DIP switch
1 on the rear panel.
