Your desired setup only requires freeing one serial port. This would be done with the upgrade to an SV-ADAHRS-200/201. You would then have
Serial 0: AF-PILOT
Serial 1: SV-ADSB-472 (74113) or SV-ADSB-470 (74112) if you haven't done the trade in program
Serial 2: SV-XPNDR-261
Serial 3: AF-ARINC
Serial 4: GPS-2020
The 2020 baud rate isn't acceptable to the AF-PILOT.Would my current setup work if the GPS-2020 was wired to the AF-Pilot serial input directly?
Unfortunately this won't work as the EFIS has to be involved with processing the 2020's data into transponder information...combination of SV-2020 + TT22 is not officially supported by Trig or Dynon, but I think it should work as an ADSB out solution.
