Having read so much about Comfort over the last few days I am becomming somewhat confused as to which ucm's can be used to program the system and which can be used to interface with third party devices. I understand about the ucm/knx ucm/cbus units, its the rs232, usb, rj45, rs485 ones that are confusing me. In addition can any of those 4 interfaces be used for both Comfigurator use and third party interfacing or is it best to keep them separate.
UCM/USB, UCM/Eth02, UCM/232 can be used to program Comfort
UCM/Eth02 and UCM/232 can also be used with 3rd party products provided the 3rd party product can be programmed to talk using the Comfort Protocol, USB is normally for connection to computers onlly
If the 3rd party product has its own protocol then use the Universal UCM with RS232, RS485 or ETH02 interface. This allows Comfort to send any command to the device and to receive commands from the device
Universal UCM cannot be used to program Comfort and it does not use the Comfort Protocol
Now that all makes sense to me. I have printed a lot of the manuals off to read and digest the information but the universal ucm with the add on and then ucm/usb etc completely confused me as to what could do what.
