Step 3 - 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 8. Connect the two ‘Transmit’ wires to the
appropriate connections on your chart plotter. Please refer to your
chart plotter manual for more information.
The NMEA0183 data port output operates at a baud rate of 38400
baud. Please ensure your chart plotter is configured to receive data
from the AIS receiver via its NMEA0183 port at 38400 baud.
Please note that the 'Receive' connections should not be connected
to your chart plotter as it is not normal for the receiver 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 AIS receiver’s NMEA0183
multiplexing feature to connect both devices to the chart plotter.
To multiplex your NMEA0183 device data via the AIS receiver
simply connect the device’s NMEA0183 output to the r and
receive - terminals as defined in the table above. The NMEA0183
input baud rate is 4800 baud. Please ensure your NMEA0183
device operates at 4800 baud.
