Garmin NMEA 2000 Backbone Cable (2M)

Enhance Your Marine Network with Reliable Backbone Extension

Building a robust NMEA 2000 network on your vessel starts with the right backbone setup. This Garmin backbone/drop cable, measuring a practical 6 feet (2 meters), serves as a seamless extension for your existing NMEA 2000 backbone or as a drop line to connect additional devices. Crafted from durable black cabling designed to withstand harsh marine conditions, it ensures stable data transmission between your chart plotters, sensors, autopilots, and other electronics without signal loss or interruptions.

Whether you're upgrading your echoMAP CHIRP series chart plotters, integrating a 9-axis heading sensor, or linking a Compact Reactor 40, this cable provides the flexibility to expand your setup efficiently. In the world of boating, where every connection counts for safety and performance, Garmin's engineering shines through with materials that resist corrosion, UV exposure, and constant vibration from rough seas.

Key Benefits for Boaters and Mariners

• Effortless Network Expansion: Lengthen your primary backbone or branch off to new instruments, keeping your dashboard clutter-free and organized.
• Superior Compatibility: Works flawlessly with a wide array of Garmin marine gear, including AIS 300/600 transceivers, GBT 10 glass bridge transmitters, GMI 10/20 instruments, GPSMAP series plotters, VHF 200/300 radios, and autopilot systems like GHP 12, 20 with SmartPump, or for steer-by-wire applications.
• Rock-Solid Reliability: Garmin's commitment to quality means this cable delivers consistent plug-and-play performance, reducing downtime and troubleshooting hassles on the water.
• Optimized for Marine Demands: The rugged construction handles saltwater splashes, temperature swings, and mechanical stresses, making it a long-term investment for serious boaters.

Perfect for Specific Setups

Ideal for echoMAP CHIRP 52cv and 52dv owners looking to add radar, sonar, or autopilot controls. It also pairs excellently with cameras like GCL 20, weather modules such as GDL 40, and fuel sensors like GFL 10, creating a unified system that shares real-time data across your helm.

Why This Cable Stands Out in NMEA 2000 Networking

NMEA 2000 is the gold standard for marine data buses, enabling devices to communicate over a single backbone rather than a tangle of proprietary wires. This cable simplifies installation by using standard T-connectors and terminators, allowing you to daisy-chain components without custom wiring. Boaters often overlook backbone length until expansion time— this 2-meter option bridges that gap perfectly, avoiding overly long runs that could introduce noise or attenuation.

From weekend anglers to offshore cruisers, users rave about how Garmin cables maintain network integrity even in multi-device clusters. Pair it with power isolators or extenders for larger vessels, and you'll have a scalable system ready for future upgrades like advanced thermal cameras (GET 10) or fuel flow monitors (GFS 10).

Installation Tips for Optimal Performance

Route the cable along existing backbone paths, securing it away from high-heat sources like engines. Use Garmin's drop cables for perpendicular branches to instruments, ensuring terminators at both ends of the backbone. Test connections with a network analyzer if available, but most setups power up instantly. Always prioritize waterproof fittings in exposed areas to prevent ingress over time.
