|These instructions show how to upgrade UCM, Slave or KT03 firmware using the UCM Programming Cable
If the SEM or UCM firmware is at least 6.xxx, you do not need the UCM programming cable anymore - the firmware can be upgraded over the Comfort Bus as described in http://www.comfortforums.com/forum92/3400.html
However if the module firmware is corrupt, then it can be possible to restore the firmware using the UCM Programming Cable described here
You can use the UCM/USB or UCM/Ethernet to upgrade firmware of any type of UCM or SEM or KT03 with Flash firmware. The firmware version of the target must be 5.100 or higher.
The UCM used to do the upgrade must be minimum firmware 5.178.
Note that this procedure applies to upgrading the Slave (SEM) firmware although the picture shows a UCM being upgraded.
The connections between the UCM used to do the upgrade and the UCM being upgraded are shown in the picture below. The UCM/USB is shown in the picture (ignore the RS232 connector shown)
The procedure to upgrade UCM or Slave firmware is shown here. For instructions on how to upgrade Comfort firmware, go to http://www.comfortforums.com/view_topic.php?id=1216&forum_id=4&jump_to=4472#p4472
The UCM doing the upgrading (shown on the left) is connected to the UCM being upgraded (shown on the right) via a Programming Cable which comes with every UCM/232, UCM/USB or UCM/Ethernet. The programming cable is a split cable with two connectors (6 pin and 2 pin) on one end and a single 6 pin connector on the other end
If you have two UCMs (UCM232, UCM/USB or UCM/Ethernet), one can upgrade the other, and the connections can be reversed so the other can be upgraded. a UCM cannot upgrade its own firmware
Please note that only firmware of the same type can be used to upgrade a module. For example, Comfort Ii Ultra can only be upgraded with Comfort II Ultra firmware, Slave SEM can only be upgraded with Slave firmware. UCM/232, USB and Ethernet share the same firmware. UCM/KNX, UCM/Cbus have their own tyoe of firmware so only the same firmware type can be used to upgrade the respective UCMs. eh UCM/KNX firmware cannot be used to upgarde UCM/Cbus or UCM/232, USB or Ethernet.

|If I am just upgrading a UCM does the UCM that is doing the upgrading need to be connected to the comfort motherboard or can I just feed the 12v?
|You only need to connect the 12V and COM to the UCM doing the upgrading. The KA/KB or data does not need to be connected. However it may be convenient to leave in place the white 4 way cable between the UCM and Comfort.
However the UCM being upgraded should NOT be connected at all except by the 6 way programming cable
