+1.
Plus, there was a time when some of us were mis-wiring FSK to put the +
and - on the twisted pairs so that it wouldn't cause as much noise (the
guys at Last Mile Gear tried it and it worked.
Cambium guys decided to make it real after that when they put together
the 430.
Round and round we go...

But there was a very good reason for that. + and - twisted on a single
pair greatly reduced the sync pulse spike from causing ethernet
errors. The 450 went back to the old way and I haven't seen
sync-over-power causing ethernet errors on it. Surely things have
improved with PHYs now. The PMP100 PHY is noisy and pretty sensitive
to all kinds of crap which is why I've only ever done timing port sync
on those.

Do you think that Cambium was like, "These techy types are so
enthusiastic about proprietary formats like Apple and everything, we
should follow suit and ignore all of the IEEE standards!??" Or was
it "Maybe we can MAKE them buy our CMM!" Either way, I call it a POE
failure. Glad that I never deployed 430.

Yes, it bonds the positive or 4/5 with the positive of 7/8
whichever one that is. It is the split pair powering version.
The others don't split the power pair.
The most universal one is the GigE-XXX-POE. Unless you need
split pair powering...

Does the 430APC-HV bond any pairs? Would it be the more
universal one?

Right, it electrically bonds the pairs for powering. That
will not work for
a 430 and a few others.

You want the GigE-APC-HV because it will work with
everything.
but power pairs are electrically bonded (4/5)
(1/2) (3/6) (7/8)
Will that make it not work with something?
