Advanced NMEA Setup
NMEA Interface
If you are going to interface the GPSMAP 162 with another piece of equipment such as a radar
or autopilot the unit has 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 2 seconds to update.
Activating the NMEA Data:
1. With the GPSMAP 162 turned on, press the MENU key twice to display the Main Menu. Using
the Arrow Keypad, select the ‘COMM’ tab.
2. Highlight the ‘Serial Data Format’ fi eld and press ENTER .
3. Select ‘NMEA IN/NMEA OUT’ and press ENTER .
Advanced NMEA Output Setup
The GPSMAP 162 NMEA data transmission can be customized to keep the output rate at two
seconds. If the unit is setup to output all of the available NMEA sentences, the output rate may
exceed two seconds. The ‘Advanced NMEA Output Setup’ page will allow you to turn On/Off the GPS
Status (GSA, GSV), Waypoint/Route (WPL, RTE) and the GARMIN Proprietary sentences. You can also
change the precision of the Lat/Lon Minutes.
Advanced NMEA Output Setup:
1. With NMEA In/NMEA Out selected, press the MENU key. Select NMEA Setup and press ENTER.
2. To turn a fi eld On/Off, place the highlight over that fi eld and press ENTER . Make a selection and
press ENTER again to accept the selection.
