8.5 CONNECTION OF EXTERNAL DEVICES TO THE RADIO
8.5.1 Connecting the NMEA 0183/NMEA 0183-HS to the Radio
External GPS Device Connections (NMEA 0183 4800 baud or NMEA 0183-HS 38400 baud)
The GX2400 can select the NMEA baud rate between “4800 bps” and “38400
bps”. Refer to section “
19.9 NMEA 0183 IN/OUT
” for selection.
NMEA Input (GPS Information)
• The transceiver can read NMEA 0183 version 2.0 or higher, and NMEA
0183-HS version 1.01 or higher.
• The NMEA 0183 input sentences are GLL, GGA, RMC, GNS, GSA, and
GSV (RMC sentence is recommended).
• If 4800 baud (default) is selected:
The Yellow and Green input wires are at 4800 baud.
• If 38400 baud is selected:
The Yellow and Green input wires are at 38400 baud.
NMEA Output (DSC and GPS information)
• The NMEA 0183 output sentences are DSC and DSE.
• If 4800 baud (default) is selected:
The White and Brown wires output DSC and DSE sentences.
• If 38400 baud is selected:
The Blue and Gray output wires are at 38400 baud and include
DSC (DSC, DSE) sentences.
• GSA, GSV, GLL, GGA, and RMC sentences can be output from the trans -
ceiver using settings in the GPS setup menu (refer to section “ 19.9 NMEA
0183 IN/OUT ”).
For further information on interfacing and setting up GPS operation, contact
the manufacturer of the externally connected GPS receiver.
If you have further questions, please contact your Dealer.
8.5.2 Accessory Cables
The image and table below show the wires of the transceiver and the connec -
tions to optional devices such as an external GPS antenna and a GPS chart
plotter.
CAUTION
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 Chart Plotter, External GPS receiver, or External Speaker
strip off about 1 inch (2.5 cm) of the specified wire’s insulation, then splice the
ends together.
The transceiver uses NMEA 0183/-HS protocol to share coordinates and DSC
information to and from a GPS chart plotter.
