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-PBAR4, 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 channels may be at fault, 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.
