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

4. Select

, and press

ENTER

5. Press

MENU

to open the options menu. Select

and press

ENTER
