Note: If the Comfort Firmware is version 5.xxx you need to use the UCM programming cable to upgrade the firmware as described here.

If the Comfort firmware is version 6 and above, you do not need the UCM programming cable  - the firmware can be upgraded via Comfigurator as described in http://www.comfortforums.com/forum92/3400.html

Instructions for Upgrading Comfort Firmware using the UCM/232, UCM/Ethernet or UCM/USB using the Programming Cable


This procedure shows how to upgrade Comfort firmware. For instructions on how to upgrade firmware of another UCM or Slave see http://www.comfortforums.com/view_topic.php?id=1782&forum_id=4&jump_to=7048#p7048

Please note that a module can be upgraded with firmware of the same type. 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 different firmware types. Each module can be upgraded with the same type of firmware eg UCM/KNX firmware cannot be  upgraded to  UCM/Cbus or UCM/232, USB or Ethernet.
UCM 5.178 and above is needed to do the upgrade. Lower versions may cause the firmware to be corrupted
  1. Note that this procedure may cause the siren to turn on. The SRN terminal block can be removed before this.
  2. The Rs485 white cable between the UCM and Comfort which is used in normal operations should remain connected. The UCM doing the upgrade should have firmware UCM 7 or above
  3. Connect the UCM232, UCM/USB or UCM/Ethernet  to the product to be upgraded using the UCM programming cable (see below)
  4. Connect a shunt to the PP2 header on Comfort if it is present on Comfort. PP2 can be seen in the illustration of the Comfort PCB as below the PROG connector and to the right, and directly below the D1 Green LED.

  5. Connect the UCM  programming cable with single 6 wire connector to PP1 (PROG) on the Comfort  to be upgraded
  6. Connect the other 2 ends of the UCM programming cable to the UCM (that is used for programming) to PP1 (Connector with 4 wires) and PP3 (for connector with 2 wires).
  7. Switch on the Comfort system. The battery need not be connected. Note that the Firmware upgrade cannot be done with just the Battery connected without the AC Input from the transformer also connected
  8. The UCM should have its RDY led turned on. When upgrading Comfort, its D9 and D10 will not blink as usual. When upgrading other modules, the D9 and D10 leds will continue to flash.
  9. The keypads will start beeping continuously and Comfort will not be operating normally at this time. This is expected.
  10. DO NOT LOG IN to Comfort for this procedure
  11. Start Comfigurator 3, select the UCM connection method in Options and go to Transfer > Firmware Upgrade > By Firmware Cable connected to UCM. DO NOT Login as this will not work.


  14. Next, Comfigurator will prompt for the file to be downloaded.  The firmware upgrade files can be downloaded from http://www.cytech.biz/upgrades.html The firmware files are zipped. Unzip the file. These firmware files have the extension .cbf
  15. Navigate to the correct firmware file with the extension .CBF and click "Open". The upgrade is only accepted if the firmware file is of the same type as the Comfort being upgraded, eg ULT to ULT, You will not be able to download ULT firmware to an OPT
  16. After doing so, Comfigurator will give a warning prompt, informing users that the firmware version will be upgraded. Click on "OK" to proceed with the firmware upgrade. There will be a progress bar showing the completion % during the transfer.
  17. If Comfort is being upgraded, the keypads will beep continuously because communications with Comfort is lost.
  18. When completed (without any error), switch off Comfort, unplug the programming cable from  Comfort and the UCM.
  19. Remove the shunt from PP2 on Comfort.
  20. Switch on power to Comfort. The voice announcement "Security Off" should be heard
  21. If Comfort firmware has been upgraded, go to Transfer > System Information  jn Comfigurator, and check the firmware of Comfort
Also refer to the UCM manual which can be downloaded from
http://www.cytech.biz/ucm_manual.html

A photo of upgrading of Comfort using the UCM/USB is shown.
Note that in Comfort, the PP2 shunt should be inserted during the upgrade
The white RS485 cable connects the UCM to Comfort (which is needed for normal operation). Hence there should be two cables connecting the UCM to Comfort

A short video can be seen here https://www.youtube.com/edit?video_id=yvaNE9s9YZ8&video_referrer=watch

The picture shows Upgrading of a UCM/Cbus using UCM/USB
When the programming cable is connected to the UCM/Cbus,  and the PP2 shunt inserted on the UCM/Cbus, its D9 and D10 leds will flash in time with that on the UCM doing the programming

The UCM/CBUS should  not be connected to Comfort at this time

I Want to Upgrade the firmware on Comfort Comfort II Ultra 5.169 File system 34 Vocab version 29 to the latest version (Im having trouble with Fermax/DMO1 volume levels)
The USB UCM has a firmware version of 5.156, but I see in your notes that the minimum version for my UCM should be 5.178 to upgrade to this latest Comfort ULT5.124.
Does this mean my USB UCM needs replacing, in order to perform the upgrade?:(

No, your UCM needs to be upgraded to the latest firmware which allows it to be used to upgrade Comfort, Slaves and other UCMs. At present this requires another UCM to upgrade a UCM, ie a UCM cannot upgrade itself. You can look for a  friend who has a UCM with firmware at least 5.178 so you can upgrade each others UCM, or ask a the distributor who sold the UCM is they can do it

The new UCM firmware 6.xxx can upgrade itself without using the Programming cable. You need another UCM to do the initial upgrade to firmware version 6 but once this is done, the UCM can be self upgrading

If the Firmware Upgrade fails for any reason, the Comfort Firmware will be corrupted. It will not start and keypads and door stations will beep
Do not panic

You can use this method again to upgrade the firmware and get the system operational

Follow the same instructions.

In Comfigurator, DO NOT LOG IN or do Transfer Information or any other function because there will be NO RESPONSE due to firmware being Corrupted

Go directly to Transfer > Firmware Upgrade and select "By Programming cable Connected to UCM"
