Setting up the input from a navigation system (GPS)
In order to read navigational data (position, speed, distance and heading) from an external sensor, you must choose which interface port to use, and then which datagram(s) to read.
Context
Most global positioning system (GPS) receivers provide NMEA 0183 datagrams containing geographical latitude and longitude information, as well as current speed and sailed distance.
Several external sensors(GPS navigation, gyro compass etc) may be connected to the FX80 to provide information about the vessel's speed, position, heading and sailed distance. The FX80 must be set up to receive this information.
Procedure
1 Select the Setup icon.
The icon is located under the Main menu.
