Raymarine RayNet (F) to STHS (M) 3M Cable

Upgrade your marine electronics setup without replacing your trusted displays. The Raymarine RayNet (F) to SeaTalk HS (M) 3M cable bridges the gap between legacy systems and cutting-edge RayNet accessories, ensuring seamless data flow across your vessel's network. Whether you're linking a DSM30 or DSM300 sonar module to modern A, C, or E-Series multifunction displays, or connecting older C and E-Series MFDs with RJ45 ports to new RayNet radars and sonar units, this rugged 3-meter adapter delivers reliable high-speed performance in the harshest saltwater conditions.

Seamless Compatibility for Mixed Marine Networks

Designed for boaters who invest in quality gear over time, this cable supports a wide array of Raymarine components. It pairs perfectly with the GPM400 Sonar Sounder Module and classic C/E-Series displays, while enabling G-Series, E-Wide, C-Wide, and E-Classic MFDs to interface with next-gen RayNet devices. The RayNet female socket on one end mates securely with newer network hubs, radars, digital sounders, or cameras, while the SeaTalk HS male RJ45 plug connects to your existing HS network backbone. No more compatibility headaches—just plug and navigate.

• Ideal for retrofitting DSM30/DSM300 sounders to newer MFDs
• Links legacy RJ45-equipped displays to RayNet ecosystem
• Black jacket resists UV exposure, corrosion, and abrasion

Engineered for Extreme Marine Durability

Raymarine builds gear that thrives where others fail: pounding waves, relentless sun, and corrosive spray. This cable's tough construction features marine-grade shielding to minimize signal interference, even over 10 feet of length. Waterproof connectors seal out moisture, preventing corrosion that plagues lesser cables. Boaters report years of trouble-free service, from coastal cruisers to offshore adventurers. Its plug-and-play design means no tools or complex wiring—just secure connections that keep your sonar, radar, and chartplotter data streaming flawlessly.

Key Advantages Over Standard Network Cables

• Proven in Brutal Conditions: Withstands extreme temperatures, vibration, and saltwater immersion better than generic Ethernet cables.
• Longer Service Life: Reinforced strain relief and premium conductors reduce wear from constant boat motion.
• Unmatched Reliability: Raymarine's proprietary RayNet protocol ensures gigabit speeds without dropouts.
• User-Friendly Setup: Intuitive connectors snap into place, powering up your network in minutes.
• Peace of Mind Coverage: Backed by a limited 2-year warranty for confident on-water decisions.

Installation Tips for Optimal Performance

Maximize your cable's potential with these pro tips. Route it away from high-power lines to avoid EMI noise, especially near engines or VHF antennas. Use zip ties or cable glands for secure deck runs, and apply dielectric grease to RJ45 contacts for extra waterproofing. Test the connection via your MFD's network diagnostics—look for full-duplex gigabit link status. For multi-device networks, daisy-chain strategically to balance load, keeping sonar data prioritized for real-time fishfinding.

Pro Tip: In rough seas, double-check seating after heavy rolls; loose plugs are the #1 network gremlin.

Why Boaters Trust Raymarine Networking

With over eight decades of innovation, Raymarine powers more serious vessels than any other brand. This adapter embodies their commitment to forward-compatible systems, letting you evolve your setup piecemeal. Fishers gain crystal-clear sonar overlays, sailors plot precise courses with radar fusion, and cruisers enjoy integrated camera feeds—all without starting from scratch. It's not just a cable; it's the lifeline keeping your electronics in sync when it matters most.
