Problem Solving
Troubleshooting
In the event of poor quality or missing signal output at one or more distribution
points supplied by circuits that include the CNX-PBVR4, and troubleshooting
procedures for the other devices in the network do not resolve the problem, do the
following:
1. Verify existence of input signals(s) from the CNXRMCLV.
2. Verify that the correct (24 VDC, 1A) external Power Pack is properly
connected, and that the front panel PWR indicator is illuminated.
3. Verify pinouts on CAT5 cable connectors. Make sure crimping is secure
and that there are no shorts.
4. Verify that all CAT5 input cables and RCA output cables are securely
connected.
5. After determining which of the four signal groups may be at fault, either
perform the Video Input Compensation procedures (discussed on page 7),
or swap the input and output cables between the groups to locate the
source of the trouble. If further assistance is required, please contact a
Crestron customer service representative.
