Chapter 6 OPTION AND OTHER FUNCTIONS
6.1 NMEA CABLE
The JMA-3400 series has 4 channels NMEA0183 signal input and 1 channel NMEA2000 signal input allowing
connecting to navigation equipment, such as GPS, for own position, waypoints and speed.
It also allows connecting a GPS compass for your heading and/or AIS for displaying targets.
In order to use the above function, NMEA cable (option) is required.
・Using JRC GPS receiver, please connect NMEA4 (GPS port).
・AIS connects all NMEA port available.
<NMEA0183>
The data are received by IEC61162-1/2.
