Adding A Network Node; Additional Network Information - Lowrance LGC-3000 Installation Instructions Manual

NOTE:
If you have a double T Connector on your network that is not at-
tached to a device, you must cap the unused connector with a
NMEA 2000 cap. This will protect the pin connectors from corro-
sion. The NMEA 2000 cap looks like a terminator, but has "Cap"
stamped into the connector housing.

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.

network node
Add a new device to a NMEA 2000 bus by attaching a T connector be-
tween two T connectors, between a T connector and the end terminator,
If you want to add a node at the end of the backbone (network bus) remove
the terminator from the last connector, like the figure above. Install the
new T connector and attach the terminator to the side of the connector.

Additional Network Information

Further instructions on creating or expanding a network are illustrated in
the NMEA 2000 network setup booklet, part number 988-0154-173, which
came packed with this instruction sheet.
NOTE:
You do not need a Bus Adapter Cable with this unit if you use an
approved Devicenet NMEA 2000 connector. Approved Devicenet
NMEA 2000 connectors work with Lowrance red connector display
units and components, so no adapter cables are needed.
