◦ Additional Garmin Marine Network cables and connectors 

are available from your Garmin dealer.

• The NETWORK ports on the device each act as a network 

switch. Any compatible device can be connected to any 

NETWORK port to share data with all devices on the boat 

connected by a Garmin Marine Network cable.

Station Connection Considerations

This device can be set up in conjunction with other compatible 

Garmin devices to work together as a station. When planning 

stations on your boat, observe these considerations.

• Devices earlier than the GPSMAP 8000 series and GPSMAP 

8500 series cannot be used in a station.

• Although it is not necessary, it is recommended that you 

install all of the devices you plan to use in one station near 

each other.

• No special connections are necessary to create a station, as 

long as all of the devices are connected to the Garmin Marine 

Network (

Garmin Marine Network Considerations

, page 3

).

• Stations are created and modified using the device software. 

See the owner's manual provided with the device for more 

information.

NMEA 2000

 Considerations

NOTICE

If you are connecting to an 

existing

 NMEA 2000 network, 

identify the NMEA 2000 power cable. Only one NMEA 2000 

power cable is required for the NMEA 2000 network to operate 

properly.
A NMEA 2000 Power Isolator (010-11580-00) should be used in 

installations where the existing NMEA 2000 network 

manufacturer is unknown.
If you are installing a NMEA 2000 power cable, you must 

connect it to the boat ignition switch or through another in-line 

switch. NMEA 2000 devices will drain your battery if the NMEA 

2000 power cable is connected to the battery directly.

This device can connect to a NMEA 2000 network on your boat 

to share data from NMEA 2000 compatible devices such as a 

GPS antenna or a VHF radio. The included NMEA 2000 cables 

and connectors allow you to connect the device to your existing 

NMEA 2000 network. If you do not have an existing NMEA 2000 

network you can create a basic one using cables from Garmin.
If you are unfamiliar with NMEA 2000, you should read the 

Technical Reference for NMEA 2000 Products

 at 

garmin.com

/manuals/nmea_2000

.

The port labeled NMEA 2000 is used to connect the device to a 

standard NMEA 2000 network.

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.

 0183 Connection Considerations

• The chartplotter provides one Tx (transmit) port and one Rx 

(receive) port.

• Each port has 2 wires, labeled A and B according to the 

NMEA 0183 convention. The corresponding A and B wires of 

each internal port should be connected to the A (+) and B (-) 

wires of the NMEA 0183 device.

• You can connect one NMEA 0183 device to the Rx port to 

input data to this chartplotter, and you can connect up to 

three NMEA 0183 devices in parallel to the Tx port to receive 

data output by this chartplotter.

• See the NMEA 0183 device installation instructions to identify 

the transmit (Tx) and receive (Rx) wires.
