To avoid the complexity of fitting another GPS antenna, and to be able to utilise the best GPS antenna on the plane, I was wondering if I can feed my Garmin GTN650 or G3X GPS data into the PAW via a serial NMEA connection. Has anyone done this? Any idea which pins in the Garmin. Does PAW decode NMEA directly?
Looking at the G3X install guide it's noted. "The G3X system can provide NMEA 0183 formatted GPS position data to an ELT, via an RS-232 output from a GDU display."
I wonder can the PAW use this same data stream, recieve only no handshake, 2 wire RS-232?
