BTW, the GigE PowerInjector+Sync that I have at the NOC running the four 450i's is the newest I have with s/n 118966. It has a pretty old Rev G Deluxe pipe on it, which is attached to the ice bridge about 6" off of the wall, but has a decent view of the west and south and is tracking 10 out of 12 sats. About 190 feet of cable to the radios. And they haven't lost sync since they've been up, about three weeks. And I just jinxed it knowing my luck.

If the orange LED is blinking, then the injector is receiving sync, and 1PPS Active should = 1 (if you have a base unit connected to see it).

Kurt, what software is your 450i running? FWIW, I have a limited number of 450i APs up, but I have some on SyncBox Junior's (don't get the GPS data) and the one PowerInjector+Sync at the NOC. All of my 450 and 450i is running 14.1.2. Perhaps Cambium changed something in 14.2+.

I would verify that the port has sync enabled. Obviously you'd need a base unit connected. I've plugged radios in backwards on more than one occasion. Injector upside down for one reason or another, so the radios ended up 4 thru 1 instead of 1 thru 4 because I wasn't paying attention. Port 4 is at the end closest to the SyncPipe/sync daisy chain ports. That's the most obvious issue if you turned off the sync pulse on a port to run an AirFiber. But if multiple people have had the same problem, then my theory is bunk.

Ok, I just put a new PMP450i on a tower and am running into the exact same problem the Original Poster had here. I have the Gigabit Power Injector plus Sync and it is blinking for receiving sync from another Sync Injector in the same enclosure via the included jumper cable and the AP is running in Autosync+ Freerun and it is not showing receiving any sync at all and it is decided to Generate its own Sync. Has been running for a couple hours now. Will keep checking back here. On Tue, Nov 22, 2016 at 1:51 PM, That One Guy /sarcasm <thatoneguyst...@gmail.com> wrote:

    all this talk of the new units i opened our box of them, is there
    a guide for the 10/100 and gigabit powerinjector jumper settings
    per brand?
    is it just the same as
    http://tickets.packetflux.com/downloads/poeinjectorjumpers.pdf
    <http://tickets.packetflux.com/downloads/poeinjectorjumpers.pdf>
    only with the pin order backward?
    and if a guy put a 3pin connector on the A/B selector, would that
    effectively put the two inputs in parallel?

        Depends on the power circuitry on the airfiber.  My guess is
        it would be ok.
        If you have a base unit, you can actually turn off the sync
        on that port and the injector will remember it, so you don't
        have to put a base unit in the field with it, just for the
        programming.   (You'd set the poweron column for the sync row
        for that port to '0').

            I just received my first powerinjector + sync today. If I
            want to power some Airfibers with these do I need to turn
            the sync off for those ports? I don't see a jumper to
            turn off sync, is it ok to provider sync on a port with
            an Airfiber? Does it hurt anything? It looks to me like
            the only way to turn off sync is buy the additional site
            monitor base thing to hookup to it and turn it off
            through the web interface?

                    Check if the packetflux says it has fix and 1PPS
                    is active on the binary tab and that the used
