ACCESSORY CABLES

The image and table below show the wires of the GX2200 and the connec-
tions to optional devices such as a PA speaker (horn), external speaker, GPS
chart plotter and an AIS receiver or transponder.
Care must be taken not to touch any of the NMEA wires to positive
12 VDC or the radio may be damaged.
When connecting the external speaker or GPS navigation receiver, strip off
about 1 inch (2.5 cm) of the specified wire's insulation, then splice the ends
together.
The GX2200 uses NMEA 0183 protocol to share coordinates, DSC and AIS
information to and from a GPS chart plotter. The GX2200 transfers AIS infor-
mation to a GPS chart plotter or PC at 38400 baud (sometimes called HS).
GPS and DSC information is transferred between 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 GX2200
may be setup to receive GPS coordinates, send DSC and AIS signals at
38400 baud. Refer to section "10.6 NMEA DATA IN/OUT" for details.
