Humminbird AS-ETH-NMEA2K NMEA2000 Black Box w/Ethernet

Unlock Seamless Engine Data Integration on Your Boat

Imagine glancing at your Humminbird display and seeing real-time fuel flow, RPM, engine temperature, and trim position—all without cluttering your dash with extra gauges. The AS-ETH-NMEA2K black box makes this possible by bridging your boat's NMEA 2000 network directly to Ethernet-enabled Humminbird units. This compact, waterproof powerhouse pulls critical performance data from engines, sensors, and other marine electronics, delivering it straight to your fish finder or chartplotter for smarter boating decisions.

Whether you're chasing trophy bass in a bass boat or monitoring systems during long offshore runs, this interface eliminates guesswork. Track fuel efficiency to stretch your range, spot potential issues early like overheating, and optimize your setup for peak performance. It's the missing link for boaters who demand more from their electronics.

Key Advantages for Serious Anglers and Boaters

• At-a-Glance Monitoring: Pre-configured instrument screens show multiple gauges simultaneously, from tachometer to battery voltage, giving you the full engine picture without flipping menus.
• Dual Engine and Tank Support: Handle data from two engines and two fuel tanks effortlessly, perfect for multi-outboard setups common in performance boats.
• Fuel Savings in Real Time: Monitor consumption rates to adjust throttle and plan trips efficiently, burning less gas while fishing farther out.
• Network Expansion: Shares NMEA 2000 data across your entire Ethernet Humminbird fleet, so every unit stays updated without repeat wiring.
• Rugged Reliability: Fully sealed against water and corrosion, it thrives in harsh marine environments from freshwater lakes to saltwater bays.

How It Bridges Your Systems Effortlessly

Installation is straightforward for those familiar with marine networking. Connect the black box to your existing NMEA 2000 backbone via a standard drop cable, then link it to your Humminbird Ethernet switch or directly to a compatible unit. Once powered up, it auto-detects available data and populates customizable data boxes on your screens.

Customize views to match your needs—resize boxes for oil pressure during trolling or prioritize GPS speed over depth while running. The intuitive software lets you drag, drop, and configure without a steep learning curve, turning raw NMEA data into actionable insights. Pro tip: Pair it with a quality Ethernet switch for multi-unit boats to distribute data flawlessly and reduce latency.

Perfect Fit for Your Humminbird Setup

This black box shines with Ethernet-equipped Humminbird models across popular series, ensuring broad compatibility for upgrades. It integrates smoothly whether you're running a single head unit or a networked console with side imaging and down imaging. Boaters often add it to enhance tournament rigs, where split-second data access can mean the difference between first and fifth place.

Focus on models with strong Ethernet capabilities for the best results, and always verify your NMEA 2000 devices output standard PGNs for engine and sensor data. This setup future-proofs your boat, ready for additional transducers or GPS sources down the line.

Maximize Performance with Smart Customization

Tailor the interface to your boating style. Tournament anglers might prioritize engine hours and water pressure, while cruisers emphasize fuel remaining and coolant temps. Experiment with layouts during dockside testing to dial in the perfect dashboard. Over time, this data helps predict maintenance needs, like impeller changes or filter swaps, keeping you on the water longer.
