Installation Manual
1.7.4.9 RS-232 CONFIGURATION PAGE
This page allows for configuration of the serial communication port on the G5. Both
the input and output serial port formats can be configurated independently. Some
input/output formats will also allow for a configurable baud rate.
A green checkmark will appear next to the input format selection when the RS-232
port is receiving valid data. A green checkmark will not appear if data has not yet been
received by the unit. A red "X" is displayed if no data has been received after an initial
time-out period, or if data has been received and then interrupted.

G5 outputs GPS data via NMEA sentences.
The proprietary format used for input of navigation data to the
G5 at a fixed baud rate of 9600 from an FAA certified Garmin
Aviation
panel mount unit. If the external GPS navigator supports both the
Aviation and MapMX formats, the MapMX format is recommended.
The preferred input format when interfacing with an external
MapMX navigator. This format is only available from Garmin units equipped
