Complete an action, based on the network type:
• In a NMEA 0183 system, connect the yellow wire
(Accessory On) to the power ground, and install a
switch (not included) between the yellow wire and the
power ground.
NOTICE
Turning off the switch prevents the device from draining
the battery when the engine is off.
• In a NMEA 2000 system, the device automatically powers
on and off with the system, and you do not need to
connect the yellow Accessory On wire.
Connecting a VHF Antenna
To transmit and receive AIS information, the AIS 800 must be
connected to external VHF antenna (not included). The device
has an internal antenna splitter that allows VHF and AIS to
share a single antenna.
1
Mount the VHF antenna (sold separately) according to the
installation instructions provided with the antenna.
NOTE: You can purchase a VHF antenna extension cable.
Go to buy.garmin.com or contact your Garmin dealer.
2
Connect the VHF antenna cable to the VHF ANT port on the
Garmin AIS 800 device.
NMEA 2000 Device Connections
NOTICE
If you are installing a NMEA 2000 power cable, you must
connect it to the boat ignition switch or through another in-line
switch. NMEA 2000 devices will drain your battery if the NMEA
2000 power cable is connected to the battery directly.
In a NMEA 2000 system, the device automatically powers on
and off with the system, and connecting the yellow Accessory
On wire is not necessary ( Connecting the Device to Power ,
page 2 ).
If you are unfamiliar with NMEA 2000, you should read the
“NMEA 2000 Network Fundamentals” chapter of the Technical
Reference for NMEA 2000 Products . Go to garmin.com/manuals

NMEA 0183 Device Connections
This diagram illustrates two-way connections for both sending
and receiving data. You can also use this diagram for one-way
communication.
To receive information from a NMEA 0183 device, refer to items
and when connecting the Garmin device.
To transmit information to a NMEA 0183 device, refer to items
and when connecting the Garmin device.
For either NMEA 2000 or NMEA 0183 systems, refer to item
when making the basic power connections ( Assigning Data to
the Device , page 1 ), ( Connecting the Device to Power , page 2 ).

Connecting the green wire to the power ground with a switch (not included)
provides a toggle to temporarily revert to silent mode (receives only, does not
transmit).
2
In NMEA 0183 systems, use the switch to power off the device when the boat
engine is off, to avoid draining the battery.
