Building a NMEA 2000 Network

The main communication channel of a NMEA 2000 network is a backbone to which your NMEA 2000 devices connect. Each NMEA 2000
device connects to the backbone with a T-connector. The NMEA 2000 backbone must be connected to power, and terminators must be installed
at both ends for the network to function correctly.
When you design a NMEA 2000 network, start by creating a diagram of the network. When creating the diagram, be as detailed as possible:
•
Include all of the devices you intend to connect to your network
•
Note the approximate location of the backbone and devices on your boat
•
Measure the distances between devices and the backbone, as well as the overall length of the backbone
•
Note the power consumption of each device (Load Equivalency Number)

Note: This diagram illustrates the NMEA 2000 data connections to each device or sensor. Some devices or sensors can be powered by the NMEA
2000 network; others may require a separate power connection. Consult the installation instructions for each device you connect to your NMEA 2000
network to be sure you supply power to the device appropriately.
When building a NMEA 2000 network, you must follow certain rules to make sure your NMEA 2000 network functions correctly. Be sure to
understand the following concepts:
•
Linear backbone construction
•
Power connection and distribution
•
Proper termination
