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.
The marine instrument connects to a NMEA 2000 network on
your boat. The NMEA 2000 network provides power to the
marine instrument and data from NMEA 2000 devices such as a
wind sensor. The included NMEA 2000 cables and connectors
allow you to either connect the device to your existing NMEA
2000 network or create a basic NMEA 2000 network if needed.
If you are unfamiliar with NMEA 2000, you should read the
"NMEA 2000 Network Fundamentals" chapter of the Technical
Reference for NMEA 2000 Products. To download the
reference, go to www.garmin.com/manuals/GNX120.
