NMEA 2000 Device Connections

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.

If you are unfamiliar with NMEA 2000, you should read the

"NMEA 2000 Network Fundamentals" chapter of the Technical

Reference for NMEA 2000 Products. Go to

Connecting to a Remote GPS Antenna

This device includes an internal GPS antenna. If your mounting

location does not provide good GPS reception, you may install a

remote GPS antenna with a female BNC connector (not

included), and connect it to the device.

NOTE: If you connected this device to a NMEA 2000 with a

GPS antenna, you can use that antenna as a GPS source

instead of installing a remote GPS antenna

Connections, page
