MATRIX AIS+ CONNECTIONS

The image and table below show the wires of the MATRIX AIS+ (GX2150) and
the connections to optional devices such as a PA Speaker (Horn), External
Speaker and a GPS Chart plotter.
The GX2150 uses NMEA 0183 protocol to share coordinates, DSC and AIS
information to and from a GPS chart plotter. The GX2150 transfers targets to a
GPS Chart plotter or PC at 38400 baud (sometimes called High Speed HS).
GPS and DSC information is transferred to a GPS Chart Plotter with multiple
ports (minimum 2) at 4800 baud (default setting).
To connect to a GPS Chart Plotter which has one NMEA port, the GX2150 may
be setup to receive GPS coordinates, send DSC and AIS signals at 38400.
Refer to section "10.10 NMEA DATA IN/OUT" for details.
