A pop-up window appears which allows the selection of the Lat/Lon format and the output rate. These
settings affect all RS-232 ports that are configured to output NMEA data. The selected speed is displayed
following the baud rate now for all ports configured for NMEA output. This feature is useful for sending
data to devices that require the full set of NMEA sentences at a slower pace.
Fast (every second): GPBOD, GPRMB, GPRMC, PGRMH, PGRMZ
Normal (every two seconds): GPAPB, GPBOD, BPBWC, GPGGA, GPGLL, GPGSA, GPGSV,GPRMB,
GPRMC, GPRTE, GPVTG, GPWPL, GPXTE, PGRME, PGRMH, PGRMM, PGRMZ
Text Out
– Selecting Text Out enables a pop-up menu to appear when the Menu key is pressed (while on
the COM Configuration Page). This pop-up menu allows setting three selections (Attitude/Air Data,
Engine/Airframe Data, and GPS Position/Velocity) to On or Off. The On setting allows the output of Text
Data as described in
.
Aviation In -
The proprietary format used for input to the G3X (baud rate of 9600) from an FAA certified
Garmin panel mount unit. Allows the G3X to display a Go To or route selected on the panel mount unit,
which eliminates the need to enter the destination on both units. If the external GPS navigator supports
both the Aviation In and MapMX formats, Garmin recommends using the preferred MapMX format.
Aviation In/NMEA & VHF Out -
Receives aviation data and transmits out both NMEA data, at 9600
baud, and VHF frequency tuning information to a Garmin Nav/Comm radio.
MapMX -
The preferred data source when interfacing with an external navigator, and is only available
from Garmin units with a WAAS GPS receiver. When MapMX data is received, the G3X display can
show more accurate information about the external navigator flight plan (e.g. DME, arcs, and holding
patterns).
