Help, UCM is not a UCM/KNX after first WRITE TO EEPROM

[TheMax74]

After the first WRITE TO EEPROM command,
Comfort says \"this is not a UCM/KNX\"

No luck after reset from comfigurator.
Same thing if i press \"Read from EEPROM\"
If i scan for UCM, Comfort says \"Other\" instead of KNX in the UCM list.

To restore the operativity of the ucm, i need to open the comfort chassis, and press the UCM/KNX reset pushbutton.

UCM/KNX 5.191
UCM05 5.178
Ultra II 5.164

PS: may be related to \"Monitor mode\" option...


Another problem, KNX commands doesn\'t work in responses.
The UCM/KNX is working, because when i press \"switch device on\" from the UCM property window, it works.

Does this happen every time after you write to the EEPROM?

No. I maded further investigations.
seems to be random. After a while, it seems to change \"his personality\". It becomes UCM/Other instead of UCM/KNX.
I need to press Ucm reset button. If i reset comfort, ucm does not resets.
Sending knx commands (simply on/off) in responses, never worked.
No LED error indications on the UCM when it freezes.

If you at Cytech have successfully tested the UCM/KNX firmware, can be a wrong firmware update transfer, the cause of my troubles?
Maybe the firmware is still at 5.132, but the user manual, says that Comfigurator 3.0.8 is able to detect if the UCM is EIB or KNX, so i think more in a faulty firmware update transfer.

Just downloaded FW 5.192
No luck, same issue.
FYI, knx commands in responses doesn\'t trigger.
I have tried a response like
- KNX On 3 52
- Siren Beep
the knx command is not executed and the siren does not beep. The rows after the knx command, are not executed.

if i swap like this
- Siren Beep
- KNX On 3 52
the siren beeps, but no knx command sent

Smell like the xml cclx file is the issue...


***NOTE: i started a new project from scratch and responses seems to work.
The problem is in my cclx file.
Tried several things then tried to delete the response comment... that work!
Strange, because there was no chars outside the ascii table in the comment.
I think this has \"reformatted\" the xml correctly, because now all responses seems to work.
If i come in touch what exactly the problem was, i tell you, because this is one of the problem in witch you can spend a lot of time to overcome!! 


For me, this issue is closed.

There is a new firmware for UCM05, UCM5.192 which should fix the intemittent wrong detection of the UCM/KNX, please download from here
If the UCM/KNX is not detected then the KNX Responses will not work. This may be the cause of the problem which you encountered

Hi

I have the same problem. The leds Ready, Busy1, Busy2 and Error are all off.
When I try to upgrade the firmware, the system says: \"Firmware upgrade encountered erros\".
When I do a \'read from eeprom\', the message is UCM is not a UCM/KNX
When I do a read confort to PC, the UCM/KNX is not found, but the others UCM are founded (z-wave, rs232)

I don\'t know how to solve this problem... Any idea?

Your issue should not be related to the earlier posts which were 3 years ago

If all the LEDs are off it probably means that there is no power to the UCM
The 4 way cable should be connected from UCM/KNX to Comfort or another UCM
You must set the UCM ID to 2. The D9 and D10 leds should both be blinking if the ID is correct


If the firmware was corrupted which should not be the case unless you tried a firmware upgrade earlier. please try to upgrade the firmware again following the procedure in http://www.comfortforums.com/forum92/2409.html.
DO NOT RESET or disconnect the UCM/KNX after a failed firmware upgrade
