Garmin GPSMAP 76S Manuale Utente

54

The Interface Tab contains one fi eld, ‘ Serial Data Format’.  This fi eld contains 

eight  settings that allow the GPSMAP 76S to communicate with computer soft-
ware and other electronic devices.

•   GARMIN — Allows the GPSMAP 76S to communicate with GARMIN 

software and other GARMIN GPS units.

•   GARMIN  DGPS — Allows the GPSMAP 76S 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 76S 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 fi eld.

•   Text Out — Allows the GPSMAP 76S 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 76S 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 will output 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 will output 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.
