I am not sure yet - why RS485 comms are down. There were no hardware changes or otherwise.
I have done the following -
1 Removed all UCMs, Keypads , IRIOs so that onlythe one USB UCM is connected. I cannot sign-in - Failed to connect to UCM. Used 1234 and my own PIN. Failed to connect to UCM message
2. Followed the post on upgrading Comfort firmware via programming cable and USB UCM. This appears to be ok. See attachment. However i cannot still signon Failed to connect to UCM.
When comfort came back after power on There was no message Security Off after the upgrade using ULT7_117.cbf. Kepads are still saying Comms failure.
I repeated the above 2 times.
I have attached the upgrade monitor and my CCLx file.
Where can I go from here? I spoken Gary Morgan and he will send a U4 chip in the post.
