- admin - 10-20-2010
If you have more than 1 UCM, eg UCM/USB, UCM/232, or UCM/Ethernet with different IDs on the Comfort Bus, please use UCM with ID =1 for IR Learning
This is because during the IR learning process, the UCm does not communicate with Comfort and will cause a Communications failure alarm if the ID is not 1
UCM with ID=1 will not cause Communications Failure alarm when it is removed from Comfort. This is why the UCM #1 shoud be reserved for use for iupload/download as it can be removed from the Bus
