Interface Tab
The Interface tab contains one field: Serial Data
Format. This field contains eight settings that allow the
GPSMAP 76 to communicate with computer software
and other electronic devices.
•
GARMIN—allows the GPSMAP 76 to
communicate with Garmin software and other
Garmin GPS units.
• GARMIN DGPS—allows the GPSMAP 76
to communicate with Garmin Differential
Correction devices. The unit can have the beacon
receiver scan for available DGPS beacon or can
tune the beacon receiver to the frequency and bit
rate of a nearby DGPS beacon.
• NMEA—causes the unit to transmit NMEA
data. It also allows the GPSMAP 76 to accept
NMEA data from another NMEA device,
like a echo sounder. The baud (speed of
communication in bits per second) is displayed
in the Baud field.
• Text Out—allows the GPSMAP 76 to output
simple text data that includes, date, time,
position, and velocity information. The Baud can
be set to 1200, 2400, 4800, or 9600 bps.
• RTCM In—allows the GPSMAP 76 to accept
DGPS information from a device supplying
RTCM data in a SC-104 format. The Baud can
be set to 1200, 2400, 4800, or 9600 bps.
• RTCM In/NMEA Out—functions the same
as the GARMIN DGPS setting except, the unit
outputs NMEA 0183, version 2.3 sentences,
GPRMC, GPGGA, GPGSA, GPGSV, GPGLL,
GPBOD, GPRTE, and GPWPL.
• RTCM In/Text Out—functions the same as the
RTCM In setting except the unit outputs simple
text data that includes date, time, position, and
velocity information. The Baud can be set to
1200, 2400, 4800, or 9600 bps.
• None—turns off all serial communication.
