NMEA 2000 Cable Connections
NMEA 2000 is a new buss network specifically designed for boats. This is a very young industry standard and, at the time of printing, few boats being built now have a NMEA 2000 buss installed. Over the next few years, however, NMEA 2000 will become much more common. To help you get the most out of this technology, your Lowrance unit is designed to work with a NMEA 2000 network as soon as it becomes available.
Connecting to a NMEA 2000 Network
Your unit can be connected to a NMEA 2000 buss, receiving sensor information from any Lowrance units attached to the buss. Contact LEI Extras (look inside back cover for accessory ordering information) for a NMEA 2000 buss adapter cable if you would like to do this. You can connect both the unit and antenna module through the antenna's extension cable (as described earlier), or you can connect the unit directly to a network port. To do so, attach the adapter cable's manual locking collar connector to the Network port on the back of the sonar unit and attach the other end to an available port on the NMEA 2000 buss, as shown in the following image.

As soon as the unit is connected to the network, it will begin receiving shared information. Please note the buss must be powered to operate. (See instructions in this section for more on powering NMEA 2000 buss.)
