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 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
Connect the cable with the 2 ends - 2 wire connector and 4 wire connector to the programming UCM (PP1 and PP3) and the end with a single 6-wire connector to the PP1 on UCM to be upgraded. PP1 is a 6 way header and PP3 is a 2 way header. The connection is shown in the picture below.
On the UCM to be upgraded, insert a shunt on the PP2 header if present. The PP2 header has been removed on later UCM Modules and PP2 is not needed for KT03. In the picture, PP2 can be seen below the green (D10) and red (D9) leds on the UCM being upgraded. In older versions of the UCM, the PP2 header may be under the submodule. If so the submodule must be removed to access the PP2 header
The UCM being upgraded should not be connected to Comfort, the only connection is to the UCM doing the upgrade via the programming cable. When the connection is made, the red (D9) and green (D10) leds on the target UCM being programmed will flash, with D9 (red) very fast so it appears steady and D10 (green) at a slower rate. IF D10 GREEN LED on the target is not blinking, then the PP2 shunt is not connected or may not be making contact. Change the shunt on PP2
Run Comfigurator, go to menu Options > UCM Interface and select USB, Serial or Ethernet and the appropriate port in the usual way.
Go to Transfer > Firmware Upgrade> By Firmware cable connected to UCM. Browse to select the firmware file with extension .cbf for the UCM to be upgraded.
When selected, the firmware upgrade will start, and will take only a minute for a UCM. The progress bar will show the completion rate of the upgrade. If the upgrade process fails or halts for any reason, just repeat the transfer > Firmware upgrade process.
When it has completed successfully, remove the cable from the UCM being upgraded and the other UCM. Also remove PP2 shunt from the UCM being upgraded.
If the firmware upgrade fails for any reason, RESET the UCM which is doing the firmware upgrade, and then try again
If you have upgraded a Slave, UCM/KNX, UCM/CBUS, UCM/GSM2, etc the firmware version can be checked using Comfigurator 3.1.3 and above via the Scan Modules function in the Modules Tab
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.
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
