Install the locking ring and o-ring on the ends of the Garmin

Marine Network cable.

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.

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.

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.
