I just sent my GTX 330 out for the ES mod to solve my ADS-B-out need. The dealer was good enough to give me a loaner unit to keep me flying in the meantime.
My GTN 635 Com/WAAS/GPS is currently connected via a single RS232 in/out pair to the GTX. The altitude source is my Dynon D100 connected to the GTN 635.
I'm trying to figure out if I will need another data connection to get the ADS-B out working when my upgraded transponder comes back.
Do I need a second RS232 connection from the GTN to the Transponder? ARINC 429? Or can one RS232 connection handle everything?
I've studied both my GTN and GTX installation manuals, and this point is still unclear to me.
Any help is appreciated!
