NMEA 2000 Network Planning and Construction

The backbone is the main communication channel of an NMEA 2000 network to which your NMEA 2000

devices connect. You must connect each NMEA 2000 device to the backbone using a T-connector. You must

connect the NMEA 2000 backbone to a power source, and you must install terminators at both ends of the

network for proper functionality.

When you design an NMEA 2000 network, you should start by creating a diagram of the network. When creating

the diagram, be as detailed as possible, observing these considerations.

• You should include all of the devices you intend to connect to the network.

• You should note the approximate location on the boat for the backbone and each of the connected devices.

• You should measure the distances between the location of each device and the backbone, and you should

measure the overall length of the backbone.

• You should note the power consumption (LEN) of each connected device.

After you create a diagram of your network, you should apply the principles of proper NMEA 2000 network

construction and adjust your plan as needed. You must understand and apply these concepts.
