Text Out
– Selecting Text Out enables a Configure Text Output button to appear when the Menu key is
pressed (while on the COM Configuration Page). Pressing this button displays a pop-up menu that 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
- Receives flight plan and navigation data from a Garmin IFR GPS navigator, and optionally
outputs frequency tuning data and receives radio status data for on-screen radio display. 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).
GTX TIS-A In -
Receives TIS A-data from a Garmin Mode-S panel-mount transponder. If the
transponder is connected to the ADAHRS 1 LRU (as shown in
), it is not
necessary to connect its output to a GDU RS-232 port.
TIS-A In/NMEA & VHF Out -
Receives TIS-A data and transmits out both NMEA data, at 9600 baud,
and VHF frequency tuning information to a Garmin Nav/Comm radio. Note that if a transponder is
connected to the ADAHRS 1 LRU (as shown in
), it is not necessary to select
TIS-A In, as the transponder data is received via the ADAHRS 1 LRU.
