I have suddenly started to get a Communication error with UCM2. My UCM2 is a zwave3 and has, up until today, been working fine. I reset the alarm as I had done a change to the programming and after resetting it announced the error.
I see RS485Comms, UCM#2 in red at the bottom of Comigurator.
I have removed the connector and put it on again, and reset again but am still getting the error.
UCM#1 is an Ethernet board and seems OK. I switched the RS485 connectors from UCM#1 to UCM#2 so that it was UCM#2 then UCM#1 but that hasn't helped.
I note the green LED is not lit on UCM#2 but is on UCM#1.If I scan for modules I get Not found for UCM#2.
Any suggestions as to what the problem might be?
