|Question: What NMEA sentences does the Colorado series units output?
|The Colorado outputs the following sentences by default:
GPRMC, GPRMB, GPGGA, GPGLL, GPBOD, GPBWC, GPVTG, GPXTE, PGRME, PGRMZ, PGRMM, HCHDG
The sentence configuration is under Setup->System->Options->Advanced NMEA Setup.
Autopilot Mode enables only these sentences: GPRMC, GPRMB, GPAPB, GPBWC, GPXTE
Under the NMEA Sentences you can toggle three groups on/off:
Status toggles GPGSA and GPGSV
Wpts/Route toggles GPRTE and GPWPL
GRMN Proprietary toggles PGRME, PGRMM, and PGRMZ
For details on the Garmin proprietary sentences, I would point you to the specification at
With regards to the pin outs, the powered wire harness will contain a wiring diagram. As for the 010-10572-00 (Rino serial cable), the DB9 connector is wired with a standard RS-232 pin out.
