I know there are a bunch of posts on installing LEMO plugs, but I just wanted to confirm everything I searched/read. The shields will go to avionics ground bus, and not the devices LO's. I know that part.
1. Does Lemo ground go to avionics ground bus, or Phone LO? I've seen references to Lemo ground as "Audio LO". Which I'm not sure is correct since that is the return line for the power lemo. Leave Phone LO empty then?
2. Does PTT button need to be between Mic LO and Mic PTT or can I use an avionics ground bus to Mic PTT input? I've read both saying just use an avionics ground, and where you have to use Mic LO for the ground of PTT.
