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 transmission can

be customized to keep the output rate at two seconds. If too many

NMEA sentences are started, the unit might take longer than two

seconds to update.
You can also set the Output Rate to Fast to output a minimum

number of NMEA sentences at 1-second intervals.

To access the Advanced NMEA Output Setup:

1. Highlight the

Setup tab on the Main Menu.

2. Select the

COM 1 or COM 2 sub tab.

3. Highlight the

Serial Data Format field, and press ENTER.

4. Select

NMEA In/NMEA Out, and press ENTER.

5. Press

MENU to open the options menu. Select Advanced

NMEA Setup, and press ENTER.

Advanced NMEA Output Setup

Use the Advanced NMEA Output Setup Page to set the output rate,

change the precision of the Lat/Lon minutes, set Waypoint IDs to

names or numbers, and turn on and off the GPS status, the GARMIN

Proprietary sentences, and Waypoint/Route (WPL, RTE).
