Hello,
I have just installed a new SEM02-M2 with firmware 5.139 to my ultra II system. I also upgraded the old firmware with a MPU01 to firmware 5.145.
I replaced a SEM02 with the new SEM02-M2. I shorted ID jumper A, B and C so it has ID 33. However the Slave is not detected. I get Communications Error Slave 1 on the keypad and Comm Failure # Slave 1 in the eventlog.
The strange thing is: i have my UCM/GSM module connected to the RS485 connector on the SEM02-M2, and that is communicating without problems with the main panel! So i am sure the KA/KB connections and the Power connections are OK.
An addition after 2 hours: the SEM02-M2 shuts itself down after about 45 minutes; the green LED goes off. When that happens; all RS485 communications beside UCM ID1 is failing (including keypads). I have disconnected KA/KB from the SEM02-M2; that restores the communication again. Obviosly my GSM module has no communication at all as it is connected through the SEM02.
What can be wrong here??
