Normally the D10 green led blinks very fast, that is the received polling from Comfort. It bibks when Comfort polls any device

The D9 red led blinks more slowly, this is reply to Comfort Poll, si it blunks only when comfort polls and the UCM replies.
If D10 and D9 are blinking the UCM is working on the Rs485 bus. If you cannot log in it may be an ethernet problem
