If interfacing the aera 795/796 with another piece of equipment (such as an
autopilot), the unit needs to be set to output NMEA data. If the NMEA output mode is
set to 'Fast', the unit will output a minimum number of NMEA sentences at 1-second
intervals. If the NMEA output is set to 'Normal', the unit will output a greater number
NMEA sentences at 2-second intervals.
Setting NMEA output mode:
1) From the Main Menu, touch Tools > Setup > Interface.
2) Touch the 'Serial Data Format' datafield. A vertical list is displayed.
3) Touch 'NMEA Out'.
4) Touch the 'NMEA Output Mode' Normal/Fast toggle button.
NMEA Sentence Output:
• Normal Mode: GPRMB, GPRMC, GPGGA, GPGSA, GPGSV, GPGLL, GPBWC,
GPVTG, GPXTE, GPBOD, GPRTE, GPWPL, GPAPB, PGRME, PGRMZ, PGRMM,
and PGRMH.
• Fast Mode: GPRMB, GPRMC, PGRMZ, and PGRMH.

USING AN EXTERNAL GPS ANTENNA (OPTIONAL)

The optional GA27C or GA25 external antenna can be used. Connect the antenna
