Installation Instructions

• If the NMEA 0183 device has only one output (transmit, TX)
wire (no A, B, +, or -), you must connect the RXB wire to
ground.
NMEA 0183 Device Connected with a Single Receive Wire
In this example, the NMEA 0183 device is receiving data from
the chartplotter.

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.

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.
