Troubleshooting
If the image does not appear
1.
Ensure that all devices are receiving power. The
transmitter's and receiver's front panel Power LEDs
indicate that they are receiving power.
2.
Ensure that the transmitter is receiving a video input.
3.
Ensure that the CAT 5 cable(s) are properly terminated in
accordance with TIA/EIA T 568A standards and that 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 that the receiver's SOG
and C Sync switches are in the correct positions for the
video output.
5.
For computer video, ensure that the transmitter's ID bit
switches are on.
For computer video on an LCD projector, ensure that the

transmitter's DDSP switch is on.
The transmission distance may be too far for remote

power. Try connecting the local 15V power supply to the
transmitter.
8.
The transmission distance may be too short. Ensure that
the UTP cable is at least 50 feet long.
9.
If the Manual/Auto switch is in the manual position,
ensure that the receiver's level controls are not set too
high. Too much level and peaking can cause display
problems.
10.
For computer video from a laptop or for ungrounded AC
distribution systems, the transmitter may need to be
grounded. See Grounding the transmitter in the CAT 5
Transmitter Family User's Manual, part #68-546-01.
