*1: The GPS chart plotter ComPort must be setup to 38400 baud (HS) to receive DSC and AIS
sentences from the GX2200 (Gray and Brown wires).
*2: The GX2200 always outputs NMEA 0183 VDM sentence at 38400.
Note: Some GPS chart plotters have a single wire for NMEA signal ground. In such a case
connect the NMEA input (–) to the GPS chart plotter's single NMEA signal ground wire, and
leave the NMEA output (–) open. In case the assignment of power supply and ground of a GPS
chart plotter to be used is different from that of the radio, connect the signal ground wire of the
GPS chart plotter to the ground terminal (GND) on the rear panel of the radio.
