Step 5 - Connecting to a chart plotter
The NMEA0183 data port provides the connection to your chart
plotter and consists of four wires colour coded as shown in the table
below and in
Figure 11. Connect the wires to the appropriate
connections on your chart plotter. Please refer to your chart plotter
manual for more information.
The NMEA0183 data port operates at a baud rate of 38400. Please
ensure your chart plotter is configured to receive data from the
Mariner X2 via its NMEA0183 port at 38400 baud.
Please note that the 'Receive' connections may not be needed
when connecting to your chart plotter as it is not normal for the
transceiver to receive data from the chart plotter
.
Connecting an optional NMEA0183 device
If you wish to connect a NMEA0183 device (such as a heading
sensor) to your chart plotter, but your chart plotter only has a single
NMEA0183 input, it is possible to use the Mariner X2’s NMEA0183
multplexing feature to connect both devices to the chart plotter.
To multiplex your NMEA0183 device data via the Mariner X2 simply
connect the device’s NMEA0183 output to the receive+ and receive-
terminals as defined in the table above. Follow the instructions in
section
4.4 to configure the Mariner X2 to multiplex the devices
NMEA0183 data to your chart plotter.

Connection to a PC
The Mariner X2 is supplied with an RS232 port for connection to a
PC. The RS232 connector can be connected directly to the RS232
port on the PC or via a serial to USB converter if no RS232 port is
available. For configuration of the Mariner X2 it is necessary to
connect to a PC if your Mariner X2 has not been pre-configured by
your dealer. See section
4 for more details of configuration.
