Hi,
i'm troubleshooting the last snag in the avionics wiring.
for some reason, the GTX328 transponder doesn't get the GPS data from the Garmin GPS-18 mouse (for the automatic on/flight time counter function), even though i checked the wiring/pins several times.
Also the same GPS feeds the Trutrak just fine (the tx line of the gps is split to the trutrak and the transponder).
anybody encountered a similar problem? what data format is the transponder expecting? what baud rate? which (nmea) message does it need? (GPRMC?)
unfortunately the install manual does not cover these points at all.
the garmin gps-18 is configurable, so there is some possibility for error in there, however i set it to mostly default values, so one would expect garmin to work with garmin ;-)
oh and by the way, the other serial in #2 (altitude encoder from the efis) works just fine.
thanks for some hints!
