All T connectors on your network probably will be connected to a device.
If you want to add another node to a working network, add another T
connector. T connectors may be purchased from LEI (ordering informa-
tion appears on the back page of this booklet). If you are adding a
Lowrance or LEI NMEA 2000 sensor, it will come with a T connector.
Adding a Network Node
You can add a node to any existing connection, anywhere along the net-
work backbone. This connection could be between a T connector and a
terminator, between two T connectors, between a T connector and a
backbone extension cable or between two extension cables. Wherever you
want to add the new node, separate the sockets of the existing connection
and install the T connector between them.
If you want to add a node at the end of the backbone (network bus) re-
move the terminator from the last connector, like the figure above. In-
stall the new T connector and attach the terminator to the side of the
connector.
In this example, a new device is added to the NMEA 2000 bus by install-
ing a T connector between a T connector and a terminator at the end of
the backbone (network bus).
Additional Network Information
