*1: The GPS chart plotter ComPort must be setup to 38400 baud (HS) to send GPS coordi-
nates to the GX2200E (Blue and Green wires) and to receive DSC and AIS sentences from
the GX2200E (Gray and Brown wires).
*2: The GX2200E 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.
In some areas powerful AM broadcast stations may be heard when in listen-
back mode. In this case change the speaker wire to 2-conductor shielded
audio cable. See the illustration below for connections.
