The image and table below show the wires of the MATRIX (GX2000) and the
connections to optional devices such as a PA Speaker (Horn), External Speaker,
GPS Chart plotter and a AIS receiver or Transponder.
The MATRIX uses NMEA 0183 protocol to communicate to a GPS chart plotter
and a AIS device. GPS Chart Plotter connections are at 4800 baud and AIS
device signalling is at 38400 baud sometimes called High Speed (HS).
