Lamp and Horn Connections

The device can be used with a lamp, a horn, or both, to sound or
flash an alert when the chartplotter displays a message. This is
optional, and the alarm wire is not necessary for the device to
function normally. When connecting the device to a lamp or
horn, observe these considerations.
• The alarm circuit switches to a low-voltage state when the
alarm sounds.
• The maximum current is 1 A, and a relay is needed to limit
the current from the chartplotter to 1 A.
• To manually toggle visual and audible alerts, you can install
single-pole, single-throw switches.

J1939 Engine Network Connection Considerations
You must use a Garmin GPSMAP J1939 accessory cable when
connecting the chartplotter to the J1939 engine network to
prevent corrosion due to moisture. Using a different cable voids
your warranty.
If you have an existing engine network on your boat, it should
already be connected to power. Do not add any additional power
supply.
This chartplotter can connect to an engine network on your boat
to read data from compatible devices such as certain engines.
The engine network follows a standard and uses proprietary
messages.
You should connect only one chartplotter to one engine network.
Connecting more than one chartplotter to one engine network
may result in unexpected behavior.
The port labeled J1939 is used to connect the device to the
existing engine network. You must route the cable within 6 m
(20 ft.) of the engine network backbone.
The Garmin GPSMAP J1939 accessory cable requires
connection to a power source and proper termination. For more

Composite Video Considerations

This chartplotter allows video input from composite video
sources using the port labeled CVBS IN. When connecting
composite video, you should observe these considerations.
• The CVBS IN port uses a BNC connector. You can use a
BNC to RCA adapter to connect a composite-video source
with RCA connectors to the CVBS IN port.
• Video is shared across the Garmin Marine Network, but it is
not shared across the NMEA 2000 network.
