GTN 650 hook up to SV-intercom

[wolf1]

Garmin GTN 650 to Skyview intercom. Have the following outputs from gtn 650 and want to know which pins on intercom to connect to.
Alert hi
Com mic audio hi
Com mic key
Com audio hi
Nav audio hi
I assume all lo go to ground. Was thinking alert hi and EMS 10 audio to pin 17, nav audio to pin 4, alert hi to pin 7, sky view audio pin 31 to intercom pin 6, sky view audio pin 13 to intercom pin 19. I have PTT both cockpits.

Also saw somewhere that sky view audio pin 31 and pin 13 should be connected together. Is that still true?

Yes, the HIs are signal and the LOs are your grounds. The advice to connect the SkyView L/R wires together is for when you're connecting them to a mono input. Since SkyView has discrete stereo inputs, you want to bring break them out, as you called out, not connect them together.

You have alert hi called out twice (once to pin 17, again to pin 7), which I'm guessing was a type-o. I think you meant the following....

GTN alert hi > 7
EMS-D10 alert > 17
GTN com 1 audio hi > 14
GTN nav audio hi > 4
SkyView Left (13) > 19
SkyView Right (31) > 6
