I have a 5500 and want to upgrade to ADSB-out with a SV-261; but that will
require reconfiguration of my serial ports.

My question is can I configure a serial port to send output to an AF-Pilot,
and take input from the 74112 ADSB-in unit?

My other serial ports would be for the SV-261 transponder, AFS-ARINC adapter,
and GPS-2020. If there is another configuration that would work with these
units please advise.
Thx!
