To use the module 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 avail-

able 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. 

A network bus is an installed and operational network cable (backbone) 

running the length of your boat, already connected to a power supply and 

properly terminated. Such a bus provides network connection nodes at 

various locations around your boat. The NMEA 2000 network is similar to 

the telephone wiring in a house. If you pick up a phone in your living room, 

you can hear someone talking into the phone in the bedroom. 
Lowrance and LEI provide all the cables you will need to create a NMEA 

2000 network. Lowrance provides T connectors and extension cables so 

you can add devices along the backbone wherever you want. Once you 

have a working network, every sensor added will come with its own T 

connector for easy expansion.  
The simplest NMEA 2000 network is a GPS or sonar/GPS display unit 

with the LGC-3000, one double-T connector, two 120 ohm terminators 

and any extension cables needed to connect them. The diagram below 

details how to set up that type of network.
