I am trying to do a firmware upgrade on two UCM05's. both are serial.

First i connect the Jumper PP2 on unit to be upgraded then the single plug to pp3.

Connect the two ends to the unit that is connected to comfort. Reset comfort. In comfigurator do a system info (which works) then transfer> firmware dwnld. select file UCM5_159.cbf.

Confirm the download.

Then I get Ucm regected firmware upgrade every time. I have tried reversing the UCM's but get same message

Both UCM's are 5.154 and comfort Ultra II 5.121.

What am i doing wrong?
