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?

Which green LED is not on in UCM 2?
The RDY LED turns on if power is applied
The D10 Green Led flashes when it is polled by Ccmfort. Id 10 is offf, it means iit is not being polled. This is probably because The KA KB wires are not connected
The D9 red led flashes when the UCM replies ie communications is goood

Thanks for the reply.It is the green LED on UCM#2 that is not on, there are no LEDs lit on the UCM.The Ethernet daughterboard has a red LED lit.
I don\'t have KA KB connected as it is connected with the RS485 cable.

Tried - nothing happening :-(
It must be faulty. I\'ll get in touch with supplier Monday for a replacement.
When I fit a replacement will Comfigurator simply put all the z-wave devices back or am I going to have delete them all from the network and start again?

I do not think it is a problem with the 4 way cable. I moved the one from UCM#1 to UCM#2 and it was the same.
There is 12V at the terminal block marked 12V and COM

OK, request for a replacement UCMZwave
when you get the replacement, do a learn from the Primary controller so that the Zwave network has your new device
You will see the old UCM/Zwave Node which is now a dead node, which you cannot remove without the working device
Check that the mappings are correct and write to Zwave

Hi - things are progressing! I received a replacement zwave UCM today and fitted it. I did as you suggested and did a learn. Things appear to be working. Now when I go to Exit Comfigurator it tells me the info has changed and do I want to write to the Eprom. I say yes and get a message, \'The HomeID & Node ID in the EEPROM differ from the values in the configuration = please read the EEPROM. I read from the EEPROM and now have only the Primary controller listed. I exited Comfigurator without saving anything and reloaded. Should I write to the EEPROM rather than read?
Also when I did the \'Learn\' the primary controller found the new interface but Comfort didn\'t seem to learn anything. The command I used on the PC was \'Send Network Information to another Controller\'.
The newly registered Cytech Controller is not appearing in the z-wave mappings.

Do another Learn on the UCM/Zwave. This should automatically Read from EEPROM. Save the cclx file
You should see the UCM/Zwave listed as secondary controller. The old UCM/Zwave may be there if you did not remove it from the zwave network using the primary controller
After doing the mapping then write to EEPROM
if you have problems send the saved cclx file to support@cytech.biz
