Audio out wiring question

Post by kwiatkma »

Can I get a verification that the new audio out features requires pin B24 on Connector B, which was reserved for audio use?

I'm thinking of wiring that to a stereo plug with a ground and plug it into the audio in, in my intercom...

Answer for the HX is yes, I think it's the same for the HXr.
I have an older HX, the pin right next to B24 (I think 25, but maybe it is 23) is a convenient ground.
For now, I ran those wires out from under the panel to an 1/8" plug, which I inserted directly into my (Lightspeed) headset control box. I am evaluating whether to leave it that way, or send it to the intercom in which case everyone will hear the warnings. Currently I have ADSB-in but not -out, so I get a lot of false traffic warnings as without the "ADSB-out" I cannot filter myself out from other traffic.

Bob,

Thanks! Yes I have an HXr, Should have clarified. My manual says B25 is NC and B23 is a serial 7 in...I don't see any ground on the B connector in the latest revision (A5) of the install manual.

I can always get ground from somewhere close.

These pins were incorrectly removed from the updated manuals. Pin B24 is still audio output and B25 is still audio ground. The audio ground may be a less noisy ground reference for audio than other grounds.
