Garmin NMEA 2000 4-Port Backbone Kit, 2 m Cables, Terminators

Overview

The Garmin 010-11442-10 is an NMEA 2000 four-port backbone kit for building a basic marine electronics network on board. It gives you the core backbone hardware in one package, including a 4-port T-connector, a 2 m backbone/drop cable, a 2 m power cable, and male and female terminators.

This kit is useful when adding or organizing NMEA 2000 equipment around a helm, electronics locker, or other protected installation area where several network devices need clean connection points. The four-port layout helps keep the backbone compact while still leaving room for multiple drops, and the included terminators support the proper end-of-backbone layout required for an NMEA 2000 network.

Key features

• Builds a basic NMEA 2000 backbone for compatible marine electronics, sensors, and network accessories.
• Four-port T-connector gives several connection points in one compact backbone section.
• Includes a 2 m backbone/drop cable for routing between nearby network components.
• Includes a 2 m power cable for supplying power to the NMEA 2000 network.
• Male and female terminator connectors are included for completing the backbone ends.
• Helpful for helm upgrades, electronics refits, and small network layouts where the backbone needs to stay organized.

Installation and setup

Install the backbone where the connectors can stay supported and protected from strain, standing water, and repeated impacts. The 2 m cable length works well for short runs behind a console, inside a cabin panel, or between nearby electronics locations.

NMEA 2000 networks need proper termination at both ends of the backbone, and this kit includes the male and female terminators needed for that layout. The power cable should be connected as part of the network plan so the backbone is powered correctly for the devices connected to it.

Compatibility and fit

This kit is for NMEA 2000 network installations. It is not a standalone sensor, display, or data converter; it is the backbone hardware used to connect compatible NMEA 2000 equipment so devices can share data across the vessel network.

It is a practical match for boat owners, installers, and refit projects that need a simple backbone section rather than individual connectors and cables sourced separately.
