Re: [AFMUG] SyncInjectors and PMP450i

That's exactly the problem that the RevI injectors will fix. The reason it went away with a higher voltage is that the bottom of the dip that I showed in one of the traces above at the start shifts upward with voltage. So at 52 volts it doesn't dip as close to zero. As long as that dip isn't

Motorola could have done us all a favor by just superimposing a 1 or 2 volt drop on the power than totally interrupting it. Just put a 1 Hz square wave at the top of the power. The total interruption and terribly narrow pulse width has cause lots of issues over the years. From: Forrest

Depends on the radio. The 450i needs to voltage to drop below 30V (from 48 or 56V), so still a pretty nasty drop. Others are worse. On Tue, Nov 10, 2015 at 2:26 PM, Bill Prince wrote: > Oh wow. A simple solution. > > In fact I bet Forrest could do something like that

The expansion bus communication in the SyncInjectors and PDUs is redundantly powered through their main inputs and the expansion. So yes, you'd have to cut both the main and the exp. power to cycle them. I have seen many issues with the SyncPipes over the years. Sometimes they just go stupid

It's a bit more complicated than that.. Yes, the pulse is effectively fed through the syncinjector. The injector doesn't (as an example) realign the pulse, or anything like that. It does, however, control the length of the power interruption and is able to simply ignore a pulse if it deems it

Thanks, that's makes more sense. Yeah, it's really weird. All APs say they lose sync at the same time which points to the SyncInjector, but all of the stats look fine. As far as voltage, I have a couple sites on regulated 24 and a couple others on Mean Well AD-155's which put out 27.6 float
