I'm curious if the Remote is incompatible with Kemper Profilers that were released before the remote was released. I don't think it should be an issue.
I bought Kemper (unpowered rack) with the remote. I use it with a PoE injector in my rack (one that's approved for use in the manual).
A friend has a Kemper that was made before the remote was a thing, and when we tried to connect my remote, it either wouldn't connect, or would barely power with just a line in the screen. We used the included cable from when I initially bought mine.
It shouldn't be a compatibility issue, but is it? Am I missing something??
