Dynon Shoutout

[WenEng]

I called Dynon tech rep for answer to a question about the Arinc 429 module pin 20 ground. How do I use it? Why did Stein diagram run a wire from the GTN 750 P1001-46 serial ground to Dynon's Arinc pin 20. Should I splice and run a ground from the Airinc pin 20 to Airplane ground?? I got their phone mail and left a garbled question about all this.. Seriously,,, Mike called me back in 10 minutes and walked me through it, answering my questions... Thanks Dynon..
Pin 20 is hardly ever used.... You don't need to run another wire to ground from it. It is a ground through the Skyview network.. Running the GTN 750 serial ground into pin 20 is insurance... or something like that. I confess to being electrically challenged.
