Not really sure what the major difference is between "timing port" and
"aux port" sync/timing, but whatever it is, the 450i is certainly
different. The aux port is the traditional timing port, but not exactly?
The other thing to note, that Forrest mentioned here or the AF list, is
the 450i and presumably the 450m, even though they will take either
polarity on all pairs, two pairs + and two pairs -, they MUST have
negative on 4&5 and positive on 7&8 for sync over power to work. And
450i doesn't NEED 4-pair power, 2 will work if you're not using the POE
output on the aux port.
Mostly off the top of my head, feel free to correct. Hopefully this
table makes it onto the list properly formatted.

So, I've been working on a document with several columns:
Radio Type - the name/model of the radio.
Timing Port Sync (checkbox) - Does the radio support 'traditional'
sync via the timing port?
Aux Port Sync (checkbox) - Does the radio support newer 'aux port'
sync via the aux port?
uGPS-style power output - Can the radio provide power on the timing or
Aux Port for a GPS receiver?
Canopy Style Sync - Does the radio support traditional 'interrupt the
power' sync via the power port.?
Cambium Style Sync - Does the radio support the newer 'interrupt the
power' sync via the power port?
Voltage range supported
Pinout required (i.e. which pins are positive, which are negative,
etc) - most of this I know for all of the radios.
Other notes.
I've gotten as far as the 4-5 lines I know (newer 100PMP, 320/430PMP,
450PMP, 450iPMP, ePMP, maybe 1-2 others). A lot of them I used to
know (like when did the 100 series start supporting uGPS power?) but
don't anymore.
My intent has been to get a few more radios on it and then send it out
to the lists to help me finish it up. But since this came up I
figured it was as good of a time as any to ask for the help.
Unfortunately, I don't have the document ready in a form I can send
(it's on a paper notepad by my computer that I'm not near right now),
but since it's pretty easy to describe I figure I should be able to
just ask...
So if anyone would like to contribute one or more rows to this
document ... I.E. describe the sync and/or power status for a given
radio, that would be helpful. I'm pretty good with the AP's, but as
nick mentioned - the PTP variants are all hard to keep track of.

Lacking sync

It's extremely confusing!
