Have you checked the voltage on the comma lines?

yep 29vdc on mnet

Had the same error last week. Turned out I was missing voltage at L3 due to a poor connection in the isolator. Did a full system reset and it cleared the fault.

had it on a hotel- system 4yr old and the comms goes through the power pack before the g50- power pack failing ,thus the comms error

appreciated, off site this week now but will check out mains / power pack etc when back.

How long is the total cabling?
Do you have a booster installed?

Check the position of the cn41 plugs on the outdoor board.
