When writing to EEPROM, error: \"UCM 2 is not a UCM/KNX2\" or other type of external UCM which has been installed
This is because the UCM used with Comfigurator is version 5.xxx
It needs to be upgraded to the latest version 7
However for version 5 UCM firmware you need to have another UCM to upgrade this ucm using the UCM programming cable
see http://www.comfortforums.com/forum4/1782.html
When it has been upgraded to UCM firmware version 7, then this UCM can be used to upgrade Comfort ansd the UCM/KNX2 without the programming cable, just use Comfigurator
If you do not have another UCM/USB or ETH03 perhaps you can borrow a UCM or ask your Comfort distributor to to the upgrade for you
