Simplify Your Boat's Navigation Network with the SeaTalk^ng Backbone Kit

Setting up a reliable marine electronics network doesn't have to be a headache. The Raymarine SeaTalk^ng Backbone Kit delivers everything required to build a sturdy foundation for your vessel's instrumentation system. Designed for boaters who demand seamless connectivity between displays, sensors, and other devices, this kit transforms chaotic wiring into an organized, high-speed data highway.

Whether you're outfitting a new boat or upgrading an existing setup for instruments like the ST70 series, this backbone kit ensures drop-resistant communication across your entire network. SeaTalk^ng—Raymarine's advanced protocol compatible with NMEA 2000 standards—powers radar, autopilots, chartplotters, and more with minimal signal loss, even in rough seas.

Complete Kit Contents for Effortless Setup

This all-in-one package equips you with the essentials to construct a robust backbone without hunting for individual parts. You'll find precisely measured cables for flexible routing, junction points for easy expansions, and protective ends to maintain signal integrity.

• Pair of terminators to cap the network ends and prevent data reflections.
• One extended 20-meter backbone cable for spanning longer distances on deck.
• Two 5-meter backbone cables for shorter runs or segmented layouts.
• Four T-pieces to branch off spur cables to individual devices.
• Network power cable for stable 12V supply directly to the backbone.

Note that displays, transducers, and spur cables are sourced separately, allowing customization to your exact needs.

Key Advantages for Serious Boaters

Raymarine builds gear that thrives where others falter—think pounding waves, salt spray, and constant vibration. This kit inherits that legacy:

• Proven Durability: Engineered with marine-grade materials that resist corrosion and UV exposure for years of service.
• Plug-and-Play Simplicity: Color-coded connectors snap together securely, slashing installation time—even for DIY enthusiasts.
• Scalable Design: Start basic and add devices like multifunction displays or wind sensors as your boating evolves.
• Superior Reliability: Low-power draw and shielded cabling minimize interference from engines or radios.
• Backed by comprehensive support resources for confident troubleshooting.

Boaters report fewer glitches and faster diagnostics, keeping focus on the water rather than wiring woes.

Step-by-Step Installation Insights

Route the backbone along your boat's centerline for optimal access, securing with cable ties away from heat sources. Connect power at one end, add terminators at both extremities, and use T-pieces for spurs—no more than 1 spur per 5 meters to avoid voltage drops.

Pro tip: Test continuity before sealing conduits. For ST70 integration, align spurs directly to instrument pods for real-time data sharing on speed, depth, or heading. Common pitfalls? Over-tightening fittings—finger-tight plus a quarter turn suffices for watertight seals.

Expand later by inserting inline terminators temporarily during additions, preserving your network's health.

Enhance Your On-Water Experience

Integrate this backbone with Raymarine's ecosystem for autopilot evolution, fishfinder precision, or AIS awareness. Anglers love the stable sonar feeds; cruisers appreciate synced charts across helm stations. It's the unseen hero enabling smart boating decisions, from reef navigation to tournament runs.

Maintenance is straightforward: Annual inspections of connections ensure peak performance. Rinse with fresh water post-salt exposure, and you're set for another season.
