Communications Port Configuration

The unit has one NMEA 0183 version 2.0 compatible communication
port, or com port for short. The Com Port Menu, which is accessed from
the System Setup Menu, allows you to configure the communications
port to send or receive data to another electronic device, such as an
autopilot. The com port can be used for either NMEA, DGPS or SiRF
Binary data transfer.
