Advanced NMEA Output Setup
If you are going to interface the GPSMAP 276C with another piece of equipment (such as a radar or
autopilot), the unit needs to be set to output NMEA data. The NMEA data can be customized to shorten
the update time from the unit. If too many NMEA sentences are activated, the unit may take longer than
two seconds to update.
The GPSMAP 276C NMEA data transmission can be customized to keep the output rate at two
seconds. If the unit is set up to output all of the available NMEA sentences, the output rate may exceed
two seconds.
