Anybody have a great CCL troubleshooting guide for Warrior / Probe?

[Horizontal]

Trying to troubleshoot CCL problem on stage job, without backups!  CCLs look good, check good, getting collar signals when checked at slip rings.  Problem is nothing on log, nor Probe CCL meter.  I was hoping someone had a good guide of flowchart on how to nail down the root cause...

Make sure that you have line plugged the line connector on the shooting panel and the cable from the interface plugged into the system connector. They are easy to get switched.
Check that CCL from the Shooting panel goes to CCL on the interface panel and not the BNC line connector.

Could be bad chip (U2) within Probe shooting panel.
