3
Install the locking ring and o-ring on the ends of the Garmin
Marine Network cable.
4
Connect the Garmin Marine Network cable to the GARMIN
MONITOR port on the GPSMAP 8500 and to the GARMIN
PROCESSOR BOX port on the GMM.
5
Connect the DVI-D cable to the MAIN DVI-I VIDEO OUT port
on the GPSMAP 8500 and to the MAIN DVI VIDEO IN port
on the GMM.
6
Connect the appropriate cable to the MIRROR DVI-I VIDEO
OUT port on the GPSMAP 8500 to another GMM, or to a
third-party display (optional).

Garmin Marine Network Considerations

The GPSMAP 8500 can connect to additional Garmin Marine
Network devices to share data such as radar, sonar, and
detailed mapping. When connecting Garmin Marine Network
devices to the GPSMAP 8500, observe these considerations.
• A Garmin Marine Network cable must be used for all Garmin
Marine Network connections.
◦ 3rd party CAT5 cable and RJ45 connectors must not be
used for Garmin Marine Network connections.
◦ Additional Garmin Marine Network cables and connectors
are available from your Garmin dealer.
• There are four NETWORK ports on the GPSMAP 8500 that
each act as a network switch. Any compatible device can be
connected to any NETWORK port to share data.
◦ Any compatible sensor, such as a radar or sonar device,
connected to one of the NETWORK ports on the
GPSMAP 8500 will share sensor data with other Garmin
chartplotters or GPSMAP 8500 stations connected to the
GPSMAP 8500 through a NETWORK port.
◦ The fifth connector, labeled GARMIN MONITOR, is
reserved for use with the primary GMM, and cannot be
used to connect to Garmin Marine Network devices.
NMEA 2000 Connection Considerations
If you have an existing NMEA 2000 network on your boat, it
should already be connected to power. Do not connect the
included NMEA 2000 power cable to an existing NMEA 2000
network, because only one power source should be connected
to a NMEA 2000 network.
If you are installing the included 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.
The GPSMAP 8500 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 either connect the
Basic NMEA 0183 Connections
These diagrams illustrate basic NMEA 0183 wiring used to connect your device to NMEA 0183-compliant devices. For more
information on the NMEA 0183 capabilities of the device, see
NOTICE
GPSMAP 8500 to your existing NMEA 2000 network or create a
basic NMEA 2000 network if needed.
If you are unfamiliar with NMEA 2000, be sure to read the
"NMEA 2000 Network Fundamentals" chapter of the Technical
Reference for NMEA 2000 Products on the included CD-ROM
or click on the "Manuals" link on the product page for your
device at www.garmin.com.
The port labeled NMEA 2000 is used to connect the GPSMAP
8500 to a standard NMEA 2000 network. The ports labeled
ENGINE and HOUSE are reserved for future use and should
not be connected to a standard NMEA 2000 network.

NMEA 0183 Connection Considerations

• The installation instructions provided with your NMEA 0183-
compatible device should contain the information you need
to identify the transmitting (Tx) and receiving (Rx) A (+) and
B (-) wires.
• When connecting NMEA 0183 devices with two transmitting
and two receiving wires, it is not necessary for the NMEA
2000 bus and the NMEA 0183 device to connect to a
common ground.
• When connecting a NMEA 0183 device with only one
transmitting (Tx) wire or with only one receiving (Rx) wire,
the NMEA 2000 bus and the NMEA 0183 device must be
connected to a common ground.
