I did search, a few times... so not sure what posts you are talking about. I did a search in the girder5 forum for 2814u (the model I have) and exactly zero posts came up. If I knew to search for PLM vs PLC vs UFC or anything else I would have, thus would not have asked the question.
Guess I don't get what the difference between the interfaces are and why it cannot be used with both? I'd think Insteon protocol would be the same in either case - and USB communications is the same?
