Furuno LAN Cable Assembly - 5M RJ45 x RJ45 4P

Enhance your marine navigation setup with the Furuno LAN Cable Assembly, a robust Ethernet solution engineered for seamless connectivity in demanding saltwater environments. This 5-meter cable bridges your Furuno NavNet 3X or TZTouch systems directly to a PC, enabling smooth data transfer, software updates, and network integration without the hassle of unreliable connections. Built to withstand the rigors of boating—from rough seas to constant exposure to moisture—it's the go-to choice for anglers, cruisers, and commercial operators who demand unwavering performance.

Why This LAN Cable Stands Out in Marine Networking

In the world of marine electronics, a simple cable can make or break your system's reliability. Furuno's design prioritizes marine-grade durability with a flexible blue jacket that resists abrasion, UV rays, and corrosion. Unlike generic Ethernet cables that fray or fail under vibration and humidity, this assembly uses high-quality RJ45 connectors with precise pin alignment for gigabit-capable speeds, ensuring low latency for real-time chart plotting and radar overlays.

Users rave about its plug-and-play simplicity: no crimping tools needed, just straight-to-the-point connectivity that keeps your bridge or helm station clutter-free. Whether you're expanding your NavNet network or linking to PC-based charting software, this cable delivers consistent results, reducing downtime and frustration on the water.

Effortless Installation for Any Boater

Setting up this cable takes minutes, even if you're new to marine wiring. Follow these steps for optimal results:

1. Power down your NavNet unit and PC to avoid electrical issues.
2. Locate the Ethernet port on your Furuno display (typically on the rear panel) and the LAN port on your PC.
3. Plug one RJ45 end firmly into the NavNet's Ethernet hub or switch—listen for the click.
4. Route the cable neatly along your console or bulkhead, using cable ties to secure it away from moving parts.
5. Connect the other end to your PC's Ethernet port.
6. Power up, configure your network settings via NavNet's menu (IP address often auto-assigns), and test connectivity with a ping command.

Pro tip: For longer runs or multi-device networks, pair it with Furuno's NMEA2000 hubs to create a full ecosystem. Always inspect connections before heading out to prevent intermittent dropouts from loose plugs.

Proven Performance in Real-World Conditions

Furuno's legacy in marine tech shines through here—this isn't just a cable; it's battle-tested gear. Boaters report zero signal loss over 5 meters, even with heavy radar data streams or AIS feeds. In harsh environments like offshore fishing or coastal patrols, its rugged construction outlasts off-the-shelf alternatives, saving you from mid-trip failures. Integrate it with TZTouch black box systems for PC mirroring, or use it for firmware flashes directly from your laptop, streamlining maintenance.

Compared to wireless options, this wired link offers superior security and bandwidth—no interference from ship radios or engine noise—making it ideal for professional setups.

Tips for Longevity and Troubleshooting

• Storage: Coil loosely to prevent kinks; store in a dry locker.
• Cleaning: Wipe with a damp cloth and mild soap; avoid solvents.
• Troubleshooting: If no link light, swap ports or test with another cable. Check for IP conflicts in your network settings.
• Extensions: Use Furuno inline couplers for safe lengthening without signal degradation.

With proper care, this cable becomes a permanent fixture in your setup, backed by Furuno's reputation for innovation since the early days of fishing sonar.
