NMEA 2000 Fundamentals

Linear Backbone Construction

Use the NMEA 2000 T-connectors to construct your NMEA 2000 backbone, and extend the backbone with appropriate lengths of backbone

cable if necessary. Use one T-connector per device. Use the sides of the T-connector to construct the backbone of the NMEA 2000 network, and

use the top of the T-connector to attach a NMEA 2000 device. By using only the sides of the T-connectors to construct the backbone, you create

a linear construction to your NMEA 2000 network. T-connectors can be separated by backbone cables or connected directly together.

Although the male and female connectors on the T-connectors and backbone cables will fit on all sides of a T-connector, it is very important to

use the top of the T-connector only to attach NMEA 2000 devices, not to attach other T-connectors or backbone cables.
