I'm building a frugal panel with mostly round gauges from Vans. I have a Garmin GTX 327 transponder, and a AK-350 altitude encoder. I have a few questions about pins in the connector that drive functions on the transponder that I will not be using. The question is can I just leave them unconnected, or do they need to be tied to ground or power? I've read the installation manual and it is unclear to me. Here are the pins that I'm wondering about:
Airborne sense (squat switch)
External suppression
External standby
External ident
RS-232 IN 1
RS-232 IN 2
Thanks for any info you can provide.
