    Ok so my setup was working just fine with power inserter in a room I had to paint today. Disconnected the PI from the outlet but forgot to disconnect the other two receivers in the home. We got done painting and I powered up the PI but now non of the receivers gets beyond 775 communications error. I have moved the PI to a different room and removed all power passing splitters so that from PI it's a direct line to the switch. I still get the 775 communication errors. Is it possible that my swim has gone bad???? Anything else I can try?????

    Did you unplug everything, then redo it by starting with the PI 1st and then plugging everything else in?

    Could powering on the PI with other receivers power have caused swim to fail??? Just weird since I am sure I have accidentally powered down the room with swim and not all other receiver. Every receiver was unplugged and only one is plugged in right now and made sure it was unplugged and PI plugged in for about 30 seconds

    removing the PI with receivers ON causes no harm to anything. make sure the PWR to SWM port is going towards the power passing port(s) on the splitter(s) that is the first thing to check

    splitters are no longer I. The loop. I bypassed it to ensure a direct connect from swim to,PI. The coax does have a connector in the path just so I could bypass the splitter. I will try one more time to ulug receiver and unplug PI and tha try redoing again a PI than receiver..

    Just checked all other receivers unplugged. Hr44 is on one side of PI and swim on other side. I verified the PI red side is goin to swim and other side is going to the hr44. No other splitters are in the path just two coax connectors.

    do you have a multimeter? read the voltage coming out of the PI21 towards the ODU (power to swm)

    think i have a bad PI 28. took it outside right next to the swim switch and bingo it powered and switch got hot and all receivers worked. shutdown everything moved it back inside no workie. moved back outside again not working. tech coming friday after 3 frustrating calls trying to tell the tech supports that I didn't have a swim with green led on top or outside of it

    Well right now issue is resolved. I disconnected only the coax from the PI reconnected it and the receivers started to see the swim. Still going to have them replace the PI

    Turned out to be a flaky PI-28. The installer had never seen one of these before. We also replaced all connectors and cables to dish for the swm16. Great job by Installer doing basic cabling cleanup and neat installation.
