Lowrance NEP-2 Network Expansion Port

Expand your marine electronics setup effortlessly with the Lowrance NEP-2 Network Expansion Port, a robust solution designed for seamless data sharing across multiple displays and modules. This powered Ethernet hub connects up to five compatible devices, enabling high-speed exchange of critical information like charts, waypoints, routes, radar overlays, and sonar logs. Whether you're running a single helm station or distributing screens throughout your vessel, the NEP-2 keeps everything synchronized without the hassle of complex wiring.

Built to thrive in harsh saltwater conditions, its fully waterproof construction meets IPX7 standards, shrugging off spray, submersion, and corrosive elements that plague lesser hubs. Anglers and boaters alike appreciate how it unlocks the full potential of Lowrance systems, letting you overlay StructureScan imaging from one display onto another or share live radar sweeps from Broadband 3G/HD modules. Imagine plotting a route on your bow-mounted chartplotter and watching it instantly appear on the console unit—no more redundant data entry or missed opportunities on the water.

Key Advantages for Onboard Networking

• Plug-and-Play Simplicity: No IT degree required—just connect your 5-pin Ethernet cables (sold separately) and power it up with the included 4-pin cable for instant networking.
• High-Speed Performance: Gigabit Ethernet ensures lag-free transmission of sonar graphs, weather data from LWX-1 Sirius modules, and radar returns, even during intense fishing sessions.
• Future-Proof Design: Five ports mean room to grow, with capped unused openings that maintain waterproof integrity until you're ready to add more HDS units or accessories.
• Noise Rejection: Advanced filtering cuts VHF radio interference, keeping your signals clean and reliable in crowded marinas or during radio chatter.

Perfect Fit for Lowrance Ecosystems

The NEP-2 shines brightest with HDS series chartplotters, especially when paired with sonar hubs or radar domes. It bridges older models too—think 2007 and later LCX, LMS, and GlobalMap units sporting 5-pin connectors—creating a unified network that evolves with your boating needs. Transmit live sonar control from an HDS-M to networked partners, or distribute Sirius weather overlays fleet-wide. This hub isn't just connective tissue; it's the backbone that turns disparate screens into a cohesive command center.

Rugged Specs for Real-World Demands

Streamline Your Setup and Boost Efficiency

Mount the compact NEP-2 out of the way—its low profile fits neatly behind panels or in dry boxes—then daisy-chain your displays for a clutter-free install. Boaters report fewer troubleshooting headaches and sharper decision-making, like spotting structure changes in real-time across screens. While Ethernet cables aren't bundled, standard yellow 5-pin varieties from Lowrance ensure perfect compatibility. Pair it with a Broadband Sounder for downrigger precision or radar for safe night runs, and you'll wonder how you navigated without it.
