Garmin serial/USB protocol (garmin) This format can. GPSBabel supports a wide variety of Garmin hardware via serial on most operating systems and USB on Windows. The Garmin device has to support Garmin TIS over RS-232. Use the combined part and serial number. If you have a compatible Garmin device. Aviation Alerts and Advisories. On the software label adjacent to the GTS Processor serial number tag. The new protocol allows uncertified Garmin displays.
Many GPS units have serial data streams that publish enough data to display a basic HSI page on Dynon products, and can provide groundspeed and waypoint information to enhance the EMS fuel computer. The following products may be connected to the serial inputs on any Dynon product, including the HS34. If your system includes the HS34, your GPS must be connected to it.
EFIS/EMS settings are made in:
- EFIS > SETUP > HSI > EFIS SERIAL
- EMS > SETUP > GLOBAL > EMS SERIAL
HS34 settings are made in:
- EFIS > SETUP > HSI > -HS34- > SERIAL
The following two GPS serial output formats are supported:
NMEA format
- It does not matter what version of NMEA you are using.
- Baud rate must be 4800 or 9600. The baud rate will be auto detected.
- Must provide the following sentences.
- GPRMB - This sentence is needed always. It contains core position, speed, and satellite data.
- GPRMC - This sentence is needed always. It contains basic navigational data, including information about origin/destination waypoints and course deviation
- GPGGA - Only needed if you want GPS altitude
- GPBOD or GPAPB - One of the two sentences must be present, but you don't need both. Contains course direction information. If neither are present, the OBS will always indicate 360.
Aviation format
Serial Protocol Interface
- Any GPS that outputs the Aviation format can be used.
- Baud rate must be 9600.
- Some GPSs have a 'MAPCOM' setting. This is usually equivalent to Aviation format.
- Apollo GPSs may or may not work. They need to be set to MAP mode. (Some Apollo GPSs can only be set to MAPCOM mode.)
