Garmin GPSMAP 8X10 Installation Instructions Manual page 4

◦ 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
• Stations are created and modified using the device software.
See the owner's manual provided with the device for more
information.
NMEA 2000 Considerations
®
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
/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
3).
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.

NMEA 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.
