RS232 UCM not communicating after upgrade to 7.XX
#1
We have an existing installation that we have recently upgraded for the customer. The set up was using a UCM with an RS232 daughter board to connect to a centralite system.
After upgrading the UCM to 7.XX there appears to be no communication out of the UCM.
When an RS232 communication is sent...- There is a flashing LED on the main board L10 L11 - NO flashing LED on the UCM D9 and D10
Am I correct in saying that the LED\'s D9 and D10 should flash when an RS232 communication is sent?

D9 and D10 flash when there is communication woth Comfort on the RS485 busIf D9 and D10 are not blinking there is no comms with ComfortD11 and D12 are for communications with Rs232

More to the point it was working BEFORE i upgraded to 7.XX form 5.XXX
Are you able to test this with a 7.XXX version?

Can you send the cclx file to

The cclx file is OK. Upgrading from UCM v5 to v7 should not affect it. 

The Responses to send mesages to Centralite should work (but whether the commands to centralite work is not known because we do not have any centralite here). 

You said that D9 and D10 were not blinking, is that the case? if so then the ucm is not being polled, and that does not have anything to do with the firmware or programming.

If that is fixed, then when you send a command to Centralite, the D11 (Red) LED (NOT D9) should blink meaning that a message is being sent to the Rs232 interface.

Another suggestion not related to this issue. The programming UCM should always be at UCM ID 1 and any other interface UCM should be ID 2 or more. This is because for UCM ID1 can be removed from the network without causing a Communications Failure alarm. UCMs at other IDs when removed will cause Comms failure alarm

Centralite
Were you aware that they are no longer manufacturing Centralite litejet or the larger version.... think they went into receivership a couple of years ago.
We do have software if anyone is in trouble OR can be upgraded without tooo much hassle to KNX.

I think they were announcing new products in dec 2018 si i would be surprised if they went into receivership

so i have a test rig set up
mimics the file i sent you
on UCM1 (the centralite UCM) ( RS232 daughter board in place but NO RS232 \'load\") D11 D12 DO NOT flash when I send an RS232 command.
Howeveron UCM2 (the network UCM) D11 D12 DO flash when I send an RS232 command.

Does the RS232 command get sent universally to all boards and only flashes if it sees an RS232 handshake (even though the response is addressed to only a SINGLE UCM !).

The RS232 command gets sent only to the UCM that is addressed.

Your results indicate that you have mixed up the addresses of the UCM 1 and 2.

I suggest yiou scan for modules, check which is centralite, check the response and write to Comfort That will sort out the problem

My results may indicate that BUT I\'ve DOUBLE checked.
The leds on the UCM2 flash when i send a Centralite response which is directed to UCM1.
I am using the file i sent you.
Are you able to replicate the scenario.
I still have set up on bench -
