GPS Antenna/Receiver Module
The LMS-332 and LMS-337CDF packages include the LGC-2000 GPS
module. This device contains the unit's external antenna and receiver
for GPS and WAAS signals. The antenna/receiver module comes with a
25-foot Y-adapter 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-2000 can communicate with your GPS unit either directly
(using the supplied extension cable) or through a NMEA 2000 network.
NOTE
See the module’s instruction sheet, publication part number 988-
0147-981, for complete installation instructions.
In an automobile, you may achieve good results by simply 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. If dashboard reception is poor, simply relocate the antenna mod-
ule elsewhere on the vehicle for a clearer view of the sky.
Connecting Directly to the Unit
After the module is installed, attach it to the end of the Y-adapter ex-
tension cable as shown in the following diagram. To connect it to the
unit, insert the extension cable's splitter plug into the Network socket
on the back of the unit and your system is ready to use.
