AIS 300 Installation Instructions
Connecting the AIS 300 to a NMEA 0183 Device (optional)
You can connect the AIS 300 to a NMEA 0183-compliant chartplotter using the bare wires on the AIS 300 power/data cable. Connect
NMEA 0183 bare wires to a Garmin chartplotter as indicated in the wiring layout diagram on
. Consult the diagram below to connect
the AIS 300 to a non-Garmin chartplotter. Use 22 AWG wire for extended runs of NMEA 0183 wire, if needed. If it is necessary to extend
the power wires, use 16 AWG or larger wire.

Notes:
Consult the installation instructions for your NMEA 0183-compliant device to identify the receiving (RX) A(+) and B(-) wires.
If your NMEA 0183-compliant device has only one receiving wire (Rx), connect it to the gray wire [Tx A (+)] from the AIS 300, and
If your NMEA 0183-compliant device has only one receiving wire (Rx), connect it to the gray wire [Tx A (+)] from the AIS 300, and
leave the pink wire [Tx B (-)] wire unconnected.

The AIS 300 can transmit NMEA 0183 data using either 38400 baud (default) or 4800 baud. Connect the orange/white wire from the
AIS 300 power/data cable to the negative (-) battery terminal if you would like to limit the output speed to 4800 baud. Refer to the
documentation provided with your chartplotter to determine the correct NMEA 0183 baud rate.
using the AIS 300
If you connected the AIS 300 to a chartplotter using either NMEA 2000 or NMEA 0183, refer to the Owner’s Manual provided with your
chartplotter for information on using the AIS-specific features of the chartplotter.
If you did not connect the AIS 300 to a Garmin chartplotter, ensure that you connected a power toggle switch using the yellow wire on the
