Troubleshooting
If the image does not appear
1 . Ensure that all devices are receiving power. The
transmitter and receiver front panel Power LEDs indicate
they are receiving power.
2 . Ensure the transmitter is receiving a video input.
3 . Ensure the TP cable(s) are properly terminated in
accordance with TIA/EIA T 568A standards and the RJ-45
connections are securely made. If the Power LEDs on the
transmitter and the receiver are lit green, a transmitter is
properly connected to a receiver.
4 . For computer/RGB video, ensure the receiver SOG and
C Sync switches are in the correct positions for the video
output.
5 . For computer video, ensure the transmitter ID bit switches
are on.
6 . For computer video on an LCD projector, ensure the
transmitter DDSP (Digital Display Sync Processing) switch
is on.
