RE: ETH03 keeps going offline - Krobar - 04-19-2026
Hi,
Sorry to be a pain but I'm now seeing the UCM General module go offline. Can you send me links to the latest recommended UCM General, Comfort and Comfort Slave firmwares? (Slave is not connected to any UCM but I suppose it should be brought in synch with others). Have firmware been removed from the site product URLs?
Rob
