our system is ULT 5.145, UCM05 5.164, we was upgrading firmware for ULT 5.183
our engineer did follow the step ( as it wasn't the first time for him)
but as he reported :
-connect ucm/serial to ultra board and Pc.
-switch comfort off ( no battery )
-connect programming cable to pp1 on mpu01
-connect the other ends to ucm ( pp1 , pp3 )
-switch comfort on
-comfigrator , transfer , firmware download
-navigate firmware ult 5.183 ( .cbf )
1-firmware for controller type 254 v5.183.cbf will be upgraded ( ok )
when we tried again, the attached message appear "product number or type doesn't match"
and error msg on the keypad "keypad appear message " ID#1 VER 1.08r "
You need to use UCM 5.178 or above to upgrade firmware. Your version 5.164 is not able to recover from an error like this during the upgrade. See forum http://www.comfortforums.com/forum4/1783.html whuch states the minimum UCM firmware to be used
If you have another UCM, you can use one to upgrade the other to the latest firmwqare UCM 5.200 so both are up to date
Once you have upgraded the firmware you can use it to complete the upgrading of the Comfort firmware
