Garmin GPSMAP 8500 Black Box Installation Instructions - Page 5

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). 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. 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 NOTICE 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 inline 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 Item Description GPSMAP 8500 NMEA 2000 drop cable NMEA 2000 power cable Ignition or in-line switch 12 Vdc power source NMEA 2000 terminator NMEA 2000 T-connector NMEA 2000 backbone cable 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. Basic NMEA 0183 Connections These diagrams illustrate basic NMEA 0183 wiring used to connect your device to NMEA 0183-compliant devices.
