This is a question about using shielded cable, grounding the shield, and using ground wire.
Just trying to get a feel what the majority of you did during your install.
I connected my flight plan out (GTN650) to my Aero 660 portable.
I connected "just one wire" as some of you instructed. It works fine. No shield, no ground.
I now need to connect ADSB out from the GTN650 to an input on the GTX330ES transponder.
I also need to connect serial altitude out from my Encoder to the GTX330ES transponder.
Several folks here are saying "all you need is one wire for each". But the manual is showing I need to use the signal wire, a RS232 ground wire, and shielded cable.
What is the correct answer? Can someone please go into detail
