Garmin NMEA 2000 Backbone/Drop Cable (1 Ft.)

Enhance Your Marine Network Setup with Precision

Building a reliable NMEA 2000 network on your boat requires the right components for seamless communication between devices. This compact 1-foot backbone/drop cable from Garmin steps in as the perfect solution for fine-tuning connections without adding unnecessary bulk. Ideal for tight helm stations or extending your backbone just enough to reach that extra sensor or display, it ensures your GPS, autopilot, radar, and instruments stay in sync during long voyages.

Unlike longer cables that can introduce signal noise or clutter your deck, this short extension keeps your setup clean and efficient. Mariners appreciate its rugged construction, designed to withstand saltwater splashes, vibrations from rough seas, and constant exposure to the elements—delivering uninterrupted data flow when you need it most.

Key Advantages for Boaters and Installers

• Versatile Connectivity: Use it as a backbone extender or drop cable to link devices directly, simplifying complex installations on sailboats, center consoles, or yachts.
• Plug-and-Play Simplicity: Features standard NMEA 2000 connectors that snap into place, reducing wiring errors and setup time—even for DIY enthusiasts.
• Space-Saving Design: At just 1 foot, it's perfect for minimizing cable runs in crowded panels, preventing tangles and improving airflow around electronics.
• Durability Built for Marine Life: Black jacket resists UV rays, abrasion, and corrosion, ensuring long-term performance in harsh coastal environments.
• Network Reliability: Maintains signal integrity across your entire system, supporting high-speed data for real-time navigation and autopilot control.

Broad Compatibility Across Garmin Ecosystem

This cable integrates effortlessly with a wide array of Garmin marine gear, making it a staple for upgrading or expanding your setup. It's confirmed to work with:

• AIS 300/600 blackbox transceivers for collision avoidance.
• GBT 10 audio servers and GCL 20 cameras for enhanced onboard monitoring.
• GDL 40 weather receivers and GPS 19x sensors for precise positioning.
• GHP 12, GHP 20 autopilots, including those with SmartPump or for Viking/Yamaha systems.
• GMI 10/20 instruments, GPSMAP series chartplotters, and VHF 200/300 radios.
• EchoMAP CHIRP models like 52cv and 52dv for sonar integration.

Whether you're wiring a new multifunction display or adding radar to an existing backbone, this cable bridges the gap reliably.

Practical Installation Tips for Optimal Performance

Getting your NMEA 2000 backbone right can transform your boating experience. Start by planning your backbone layout: run the main trunk along the length of your vessel, using T-connectors for drops. Insert this 1-foot cable where you need a subtle extension—perhaps between a power tee and your chartplotter.

Pro tips:

1. Power your network from a single 12V source with an inline fuse to avoid ground loops.
2. Keep total backbone length under 100 meters (328 feet) and drops shorter than 6 meters (20 feet) for best results.
3. Secure cables with zip ties away from engines and antennas to minimize interference.
4. Test connections with Garmin's configuration software to verify device recognition.

These steps ensure rock-solid performance, whether trolling for fish or crossing open water.

Why Mariners Trust This for Their Networks

In the world of marine electronics, reliability isn't optional—it's essential. This Garmin cable stands out for its proven track record in real-world conditions, from weekend warriors to professional crews. It supports the low-power, high-data demands of modern networks, letting you focus on the horizon instead of troubleshooting.

Pair it with Garmin's ecosystem for features like shared waypoints, engine data overlays, and autopilot integration that elevate your command of the water.
