I can\'t remember if I asked this before but can the UCM/CBus firmware be upgraded? The base board looks like a UCM05 with a CBus plugin. Will I mess up the UCM if I try to load the UCM05 firmware, release 5.178, on it? It currently runs 5.154.

UCM05 and UCM/Cbus firmware are completely different. You cannot upgrade UCM/Cbus with UCM05 or other types of firmware. You can upgrade UCM/Cbus with the same type of firmware only. UCM/CBus 5.154 is currently the latest.
