Video Input and Output Considerations
This device allows video input from composite video sources
and video output to a monitor, depending on the model. When
connecting video input and output sources, observe these
considerations.
• The chartplotter may have one composite-video input port
labeled CVBS IN or two composite-video input ports labeled
VIDEO 1 and VIDEO 2.
◦ The composite-video ports use BNC connectors. You can
use a BNC to RCA adapter to connect a composite-video
source with RCA connectors to these ports.
◦ The video from sources connected to these ports is
available only for display on the device or on an additional
monitor connected to the device. Composite video is not
shared across the Garmin Marine Network or NMEA 2000
network.
• The chartplotter may have one DVI-D video output port. You
can connect a DVI-D or DVI-I cable to the port to view a
mirror image of the screen on a computer monitor or HD TV.
◦ If your device includes a DVI cable connector, a rubber
gasket is included. This gasket must be installed between
the DVI port and cable connector to avoid damage to the
connector.
◦ If needed, you can use a DVI-D to HDMI
®
adapter to
connect to an HD TV or other HDMI compatible display.
◦ Although it is recommended to use DVI cables sold by
Garmin, high-quality third-party DVI cables may be used.
You should test the DVI cable by connecting the devices
before routing the cable.
J1939 Engine Network Connection Considerations
NOTICE
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
information on connecting to your engine network, see the
manufacturer's engine documentation.
