That's the kicker here. A couple of these sites have 450 APs and I disabled the on-board and power port timing. That forces it to sit on the timing port and I still had no data. I should've seen something, like receiver info, 0 visible and 0 tracked sats, but all I got was the "... if this is a remote AP..." message.

And in reality, if an AP (FSK, 430 or 450) is receiving sync via power port, it listens for and displays data on the timing port anyway. I have a couple sites now feeding sync over power via SyncInjector and I left the parasitic pipes in place. Remember I asked about that? It works. :) The difference is the 450 iGPS. They internally switch the serial data circuit from the timing port to on-board GPS.. BUT, if the iGPS doesn't have lock, then it doesn't switch.

I believe (but am not more than about 50% certain) that there was a version of the cambium software which didn't update the GPS status screen unless it was using that device as it's sync source. Which was frustrating since you couldn't tell why you weren't getting sync from the device unless you were getting sync from the device. I'm not sure if that has been fixed or not.

I will say that there have been numerous changes to the sync reception hardware and software on the cambium side made with the intent to improve sync reliability. I'd say in some ways this has been the case, and some cases this hasn't. I think they'd be the first to admit that there have been some challenges with the automatic switching between sync sources, and I feel they still have some distance to go to fix this on a more permanent basis.

    We've seen our share of odd SyncPipe/SyncBox issues. Sometimes the
    receiver just gets confused and needs to be power-cycled. I've
    seen them reporting miles of location inaccuracy until reset.

    One issue I had with the SyncBox at multiple sites last summer is
    really weird. Power would go out and the UPS died. Came back a
    couple hours later. And then I got no sync and no data from them
    on all APs. Two of the sites we're using the parasitic power and
    running one AP through it. All of the radios were working
    perfectly fine, just no GPS data nor sync. Power cycle it,
    nothing. Leave it alone and then a couple hours later, bam, GPS
    sync and data comes back out of the blue. Even if the receiver
    can't get lock, I should see some data on the AP's GPS status
    pages. No idea what that's about.

    We have a site that starts getting sync errors once or twice a
    day. We've found if we power cycle the sync injector and the sync
    pipe, the errors "go away" for a period of 3 - 6 weeks.

    So that is our solution for the time being. We set up an alert
    when we get sync errors. At which time we power cycle the sync
    injector/sync pipe during off-hours (~~ 2AM-3AM), and wait for
    another few weeks.

    The only issues I've heard like this are specifically related to
    mounting in a bad location, and then the problem seems to come
    and go just like you expect.

    The units don't really have firmware on the unit itself,  only
    in the GPS module,  and I can honestly say we've never had to
    update a module in the field.    I don't even know how to make
    that happen at this point other than it can be done.    The
    modules come from the factory with our preloaded firmware, which
    never changes unless we switch modules, which has happened
    once,  the last time being at least a year ago.

    One caveat is that the newest syncboxes have been modified to
    work with the 450i.  So the radio driving electronics are
    slightly different, even though the firmware is the same.   This
    only is relevant to units shipped in the last month or so.

    If you can come up with the serial numbers of affected units
that might help in case something happened to a batch here (like some undetected bad modules from our supplier)

    The other thing to look at is if the status screen is really
updating on the radios. If the gps module doesn't supply data, the screen stays the same.

        We have been deploying sync box 12 units with Netonix
switches for the last 6-9 months with great success. However, several of the syncbox12's we have deployed seem to
        loose and acquire sync repeatedly until they are power
        cycled.  This affects all the customers on the tower during
that time. Is there a firmware version that fixes this? I'm not sure how to even update firmware on a syncbox? The
        Sync status tab always shows that the device is tracking 10
        or so satellites but the device is not passing sync on.  In
        some other installations we have out there they have never
        had any issues.  It seems to be several that were deployed
        about the same time that are doing this but I cant swear to
        it.  Forrest?? is there an easy fix to this or have you
        heard about this from anyone else?
