When you want to expand that connection into a more extensive NMEA
2000 network with multiple nodes, you'll need to buy a LowranceNET
"Node Kit." The Node Kit comes with two 120-ohm terminators (to re-
place the single 60-ohm terminator that came with the original kit), a T
connector and an extension cable.
LowranceNET Node Kit for a NMEA 2000 network. Includes a 2 foot
extension cable, T connector, 120-ohm male terminator and 120-ohm
NOTE:
Only one Node Kit is needed the first time you upgrade your net-
work from a simple GPS display unit and LGC-2000 mini-network
to a more expansive network. After that, just buy sensors (which
come with T connectors) or individual T connectors and cables to at-
tach additional sonar or GPS display units.

Attach these two T
connectors together,
or insert an extension
cable between them.

LGC-2000 and GPS display unit as an expandable NMEA 2000 network.
Compare the two previous drawings. The second one has one T connector
for each device (in this case two) and does not use the 60-ohm terminator
– it has been replaced with two 120-ohm terminators, one at each end of
the backbone. In this case the backbone is just two nodes connected to-
female terminator.
