Note the UCM/ETHxx cannot be used to upgrade the firmware on its own Comfort controller. You can use a UCM/USB to do this.
Or you can use UCM ethernet to upgrade the firmware of another Comfort controller connected to the ucm firmware programming cable as long as the UCMs CM9001 controller is not being upgraded
Again, the UCM/USB can upgrade CM9001 controller in all siuations so please use that
