GPS Antenna/Receiver Module Installation
The FishStrike 2000c and SeaChamp 2000C DF packages include the
EGC-12w 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 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,
unobstructed view of the sky. After the module is installed, route the
cable to the unit, plug it in the center socket on the back and your
system is ready to use. See the module's instruction sheet, publication
part number 988-0148-371, for complete installation directions.
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 module
elsewhere on the vehicle for a clearer view of the sky.
NMEA 0183 Cable Connections
NMEA 0183 is a standard communications format for marine electronic
equipment. For example, an autopilot can connect to the NMEA
interface on the unit and receive positioning information. The unit is
capable of exchanging information with any device that transmits or
receives NMEA 0183 data. This feature requires an optional accessory
cable.
NMEA Wiring
To exchange NMEA data, the unit has one NMEA 0183 version 2.0
communication port. Com port one (Com-1) can be used to receive
NMEA format GPS data. The com port can also transmit NMEA format
GPS data to another device.
