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.
Use | Backbone cable |
device to bus (maintaining linear architecture) | to rest of bus |
Attach terminator at end of bus
Existing network node
Devices connect to double T 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).
