GTX 327 encoder question

Maxrate

Well Known Member
I’m curious what is the best encoder for the GTX 327 transponder? After researching the GAE 12 it does not show compatibility with the 327. Is the tried and true ACK 30.5 the best? I do plan on going with the Garmin GDL 82/GDL 50R for ADS-b. Thanks all
 
EFIS output

Many of the EFIS systems have a built in altitude encoder. RS232 or Grey code wired directly to the 327 can give you the altitude input that you're looking for.
