Whoah..... You say 'switch polarity of the pins'.
That's wrong. A 450i should be hooked up exactly the same as a 450, just at 48VDC, not 24V. If it isn't, it will power on, but won't receive sync. -forrest On Thu, Nov 24, 2016 at 7:58 PM, Kurt Fankhauser <[email protected]> wrote: > Just logged into the AP tonight and still not receiving sync over power. > Here are the details of my setup: > > AP firmware: 14.2.1 > cable lengh from Syncpipe to Sync Injector: 8 feet > cable lengh from Powerinjector to AP: 15 feet > Syncpipe Deluxe is Revision H or H1 > Powerinjector is daisy chained from a Syncinjector that is receiving > timing pulse (Have a 3.65ghz 450AP that is receiving sync over power from > this injector) > > I don't have any Site Monitor or Base Units to verify if the sync is > turned on at the injector but I just received the injector last week brand > new.
