Simrad RI-12 Radar Interface Module

Unlock seamless radar integration on your vessel with the Simrad RI-12 Radar Interface Module, the reliable bridge between your Halo radar systems and modern multifunction displays. Engineered for marine environments, this compact module simplifies connectivity, ensuring your radar data flows effortlessly across NMEA2000 networks and Ethernet connections. Whether you're navigating busy harbors, tracking fish in open waters, or monitoring weather during long passages, the RI-12 delivers rock-solid performance without the hassle of complex wiring.

Streamlined Power and Data Management

At its core, the RI-12 handles the unique power demands of Halo radar pedestals, stepping up voltage to 36V DC during transmission for optimal pulse generation. A clear status LED glows green when actively supplying power, switching to red if there's an issue—giving you instant peace of mind at a glance. Its rugged screw-in power connector block stands up to vibrations and saltwater exposure, while silicon rubber cable glands provide watertight seals that keep moisture out even in pounding waves.

Effortless Network Integration

Connecting to your boat's backbone has never been simpler. The module features a dedicated NMEA2000 Micro-C port for plug-and-play compatibility with Simrad NSS, NSO, and other NMEA2000-enabled chartplotters. On the Ethernet side, it outputs via 10/100BaseT with a built-in LED indicator, complete with a pigtail adapter that converts internal RJ45 to the familiar external Navico yellow connector. No more fumbling with custom cables or adapters—the RI-12 is ready to network right out of the box.

Built for Real-World Boating

Designed with boaters in mind, the RI-12 accommodates both 12V and 24V DC systems, making it versatile for everything from small center consoles to larger yachts. The easy-removable access cover, secured by captive screws, lets you service connections without tools scattering across the deck. Its compact footprint fits snugly in tight console spaces, and the marine-grade construction shrugs off corrosion, UV exposure, and extreme temperatures—from freezing northern latitudes to scorching tropics.

Compatibility Across Halo Radar Lineup

Perfect for all Halo radar models, including Halo 20, Halo 24, Halo 48, and Halo Pulse Compress models, the RI-12 ensures full pedestal communication. Pair it with Simrad's Broadband Radar or even integrate into mixed-brand setups via NMEA2000. Boaters upgrading from older analog radars appreciate how it modernizes their systems, delivering high-resolution target returns and bird detection modes without starting from scratch.

Installation Tips for Smooth Setup

Mount the RI-12 near your radar pedestal or display unit for shortest cable runs. Secure the power block first, then snap in the included NMEA2000 T-connector and Micro-C cable. Use the 6ft Ethernet extension to reach your network backbone, and the RJ45 adapter for direct MFD hookups. Test the LEDs post-install: green power confirms readiness, and Ethernet activity lights up during scans. In under an hour, your radar will be painting targets with pinpoint accuracy.

Enhance Your On-Water Safety and Efficiency

Investing in the RI-12 means fewer false alarms from loose connections and more time focusing on what matters—safe navigation and productive fishing. Skippers report quicker target acquisition and reliable pulse doppler performance, even in clutter-heavy rain or sea states. It's not just an interface; it's the dependable link that keeps your radar ecosystem humming through every voyage.
