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. Some GPS systems will also provide the current heading, but this information is normally taken from the gyro.
The ship's navigation system is connected to the Bridge Control Unit using a serial port. This connects directly to an NMEA converter that transmits data as UDP packets. These packets - containing the navigation information - are sent to the FX80 Processor Unit on the Ethernet line.
The communication parameters defined for NMEA 0183 are:
You can not change any of the serial line communication parameters in the FX80 user interface. These a fixed to the standard NMEA settings.
