CAT5 MULTI VIDEO SYSTEM

4. Troubleshooting

4.1. Common Problems

In most cases, nearly every issue with the CAT5 Multi Video System can be
resolved by checking the CAT5 termination and making sure that it's pinned to the
TIA/EIA 568B wiring specification. However, there may be other problems that
cause the system to not perform as it's designed. Below are solutions to the most
common installation errors.
Problem: No video signal at the receiver.
Solution: • Check that all units are powered.
• Make sure the CAT5 cable is terminated correctly per the
TIA/EIA 568B wiring specification.
• Check Receiver cable compensation switches/knob
adjustments
• Is the display device powered on and functioning?
