Do I need a GPS or other NMEA sensors?
FarSounder's user interface software processes and displays the 3D Forward Looking Sonar information generated by the sonar. In order to take advantage of our latest in-water target stabilization and chart overlay capabilities, GPS and heading sensor information must be connected to the bridge computer via NMEA.
NMEA information is passed into the software via the user interface computer's COM port. If your computer only has USB, a serial to USB converter can be used. If you wish to read multiple NMEA streams with one COM port, a NMEA multiplexer can be used. Some multiplexers even have a built in USB converter.
The software also includes a conning display for GPS, Heading, Speed and Echosounder information. If speed and echosounder information are included in the NMEA connection, they will be displayed.
