Step 4 - Connecting to NMEA 0183 compatible equipment
The two independent NMEA 0183 data ports provide connection to your chartplotter and other NMEA
0183 compatible equipment. Each port consists of two wires colour coded as shown in Table 1 and in
Figure 9. Connect the wires to the appropriate connections on your NMEA 0183 compatible
equipment. Please refer to your equipment manual for more information.
The AIS receiver has a high speed output port which operates at 38,400baud and a low speed input
port which operates at 4,800baud. The high speed port is intended primarily to connect to a
chartplotter, while the low speed port is intended to connect to other NMEA 0183 devices. A
multiplexing feature is provided, which means any messages that are received via the low speed port
