WARNING:
The NMEA 2000 network bus is always on and constantly
drawing power. You must connect NMEA power to a
switched power source so you can turn off the network
when not in use. Failure to connect to and use a power
switch will drain your boat battery, which could stop
your boat's operation.
GPS Antenna/Receiver Module
The GlobalMap 540c BAJA package includes the LGC-BAJA GPS mod-
ule. This device contains the unit's external antenna and receiver for
GPS and WAAS signals. The antenna/receiver module comes with a 15-
foot extension cable. This module can be mounted on a flat surface or
pole, or an optional magnet is available for temporary mounting on any
ferrous surface.

You need to select an antenna installation location that has a clear, un-
obstructed view of the sky. After the module is installed, connect it to the
unit. The LGC-BAJA can communicate with your GPS unit either di-
rectly (using the supplied extension cable) or through a NMEA 2000 net-
work.
NOTE
See the module’s instruction sheet, publication part number 988-
0154-651, for complete installation instructions.
In an automobile, you may achieve good results by placing the external
antenna on the top of the dash, at the base of the windshield. A piece of
the rubber non-skid shelf liner material available in recreational vehicle
supply stores will help hold the antenna in place. This may not work well
if you have a cab-over design pickup truck camper or motor home.
