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.

If the NMEA 0183 device has only one input (receive, Rx) wire (no A, B, +, or
-), you must leave the gray wire unconnected.
If the NMEA 0183 device has only one output (transmit, Tx) wire (no A, B, +, or
-), you must connect the violet wire to ground.

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.
