AIS 300 Installation Instructions
Connecting the Receiver Box to Power
Use the AIS 300 power/data cable to connect the receiver box to a 12 or 24 Vdc battery.
Notes:
• Connect the red wire to the positive battery terminal, and connect the black wire to the negative battery terminal.
• The replacement fuse on the power/data wiring harness is a 5 A, fast-acting fuse.
• If it is necessary to extend the power wires, use 16 AWG or larger wire.
Installing the AIS 300 Power toggle
The AIS 300 can be powered on and off in one of 3 ways:
• If the AIS 300 is connected to a NMEA 2000 network, it will turn on and off with the NMEA 2000 network.
Note:
The AIS 300 is not powered by the NMEA 2000 network; however, it will turn on when it detects power on the NMEA 2000
network. You must connect the AIS 300 to power as well as to the NMEA 2000 network.
• If the AIS 300 is connected to a Garmin chartplotter using NMEA 0183, connect the yellow wire from the AIS 300 power/data cable to
the Accessory On wire from the chartplotter. The AIS 300 will then turn on or off with the Garmin chartplotter.
• If the AIS 300 is connected to a non-Garmin NMEA 0183 chartplotter, or not connected to a chartplotter at all, then you must install a
toggle switch to turn the device on and off.
◦ Connect the yellow wire from the AIS 300 power/data cable to one terminal of a single-pole, single-throw switch (not included), and
connect the other switch terminal to the negative (-) battery terminal.
◦ When you close the switch, the AIS 300 powers on. When you open the switch, the AIS 300 powers off.
Connecting a VHF Antenna to the AIS 300
To transmit and receive AIS information, the AIS 300 must be connected to a VHF antenna (not included).
Connect a marine VHF antenna to the AIS 300 using the antenna port on the device. If you have a VHF radio on your boat, connect the
VHF radio to the AIS 300 using the included RF interconnect cable according to the wiring layout diagrams starting on
.
Mount the antenna according to the installation instructions provided with the antenna.
Connecting the AIS 300 to a NMEA 2000 Network (optional)
You can connect the AIS 300 to a NMEA 2000-compliant chartplotter using your existing NMEA 2000 network, or you can build a basic
NMEA 2000 network if you do not have one on your boat. For more information on NMEA 2000, and to purchase required cables and

2000 network.
Note:
If you are unfamiliar with NMEA 2000, see the “NMEA 2000 Network Fundamentals” chapter in the
