Advanced NMEA Output Setup
If you are going to interface the GPSMAP 296 with another piece
of equipment, 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 selected the unit
can take longer than two seconds to update. You can also set the
rate to Fast to output a minimum number of NMEA sentences at
1-sceond intervals.

1. Press MENU twice to open the Main Menu.
2. Use the ROCKER to select Setup from the vertical tab list.
3. Select Com 1 or Com 2 from the row of tabs along the top.
4. Highlight the field below Serial Data Format. Press ENTER.
5. Select NMEA In/NMEA Out. Press ENTER.
6. Press MENU to open the options menu. Select Advanced
NMEA Setup, and press ENTER.
