NMEA Out - Supports the output of standard NMEA 0183 version 3.01 data at user selectable baud rate of
either 4800 or 9600. The GDU outputs data from the selected GPS source (internal GPS or external GPS1/
GPS2) via NMEA sentences.
A setting that allows switching the NMEA output between "Normal" and "Fast" speeds is accessed by
pressing the MENU Key on the Comm Page (at least one output must be set to NMEA Out) which enables
a Configure NMEA Output button to appear.
Pressing this button displays a pop-up window 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
