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
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.
