Main Menu > Setup Tab Advanced NMEA Output Setup If you are going to interface the GPSMAP 396 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 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-second intervals. To access the Advanced NMEA Output Setup: 1. Press Menu twice to open the Main Menu. 2. Use the ROCKER to select Setup from the vertical tab list. 3. Select Interface 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.
