We connected our z9 to a Clarion a couple of years ago for POC testing only. I seem to remember something that the Clarion needed the z9 to attempt the connect , then they could authorize it and finally we were able to connect. (But these are vague memories - but I so remember a multi-step procedure). The Clarion is now de-installed but I believe the FCP chipid's are still there if you need me to look at something.
