If dashboard reception is poor, simply relocate the antenna module else-

Connecting to a NMEA 2000 Network
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-BAJA, 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.
