AdvanSea S400 Repeater: Your Ship’s Command Center for Clear, Immediate Navigation Data

The AdvanSea S400 Repeater is a purpose-built secondary display that brings critical navigation metrics to the helm in a single, easy-to-read panel. Designed to pair with AdvanSea’s S400 family and share data over the AS-1 bus and NMEA 0183, it keeps wind, depth, speed, and temperature within arm’s reach, so you can focus on the water. This is especially valuable for coastal cruising, offshore fishing, and sailboat navigation where every second counts. Part Number PL67039.

Crystal clarity you can rely on

• Large, high-contrast LCD with adjustable backlighting ensures legibility across day, dusk, and bright sun, plus multi-angle viewing for crew at the bridge or helm.
• Condensation-proof surface treats moisture and mist, preserving readability in humid or spray-prone environments.
• Readouts at a glance surface speed, water temperature, depth, and battery voltage are presented clearly, reducing the need to divert attention from the water.

Smart, integrated data that stays in sync

• NMEA 0183 input and output re-displays vital data from connected devices—wind speed and direction, depth, cruise speed and distance traveled, water temperature, and electronic compass direction—so your cockpit has a unified reference.
• AS-1 AdvanSea bus compatibility enables coordinated readings and deeper interoperability with onboard electronics beyond basic NMEA data, creating a cohesive cockpit ecosystem.
• Data flow in and out via NMEA input and output ensures seamless integration with other instruments, making the S400 a reliable hub for your navigational data.

Why this repeater matters on the water

By consolidating wind, speed, depth, temperature, and compass information in one location, the S400 Repeater reduces the need to scan multiple displays or dashboards. Its robust design is tailored for real-world boating scenarios—from spray-filled decks to humid masts—while its alert capabilities can trigger external lights and buzzers to flag important events, enhancing deck reaction times. This makes it a practical upgrade for captains who demand quick, accurate situational awareness without distraction.

Who benefits most

Ideal for sailors, coastal cruisers, and anglers who rely on a single, trustworthy secondary display to reinforce their primary instruments. If you’re integrating multiple S400 devices or building a more interconnected cockpit with AdvanSea components, the S400 Repeater ensures data consistency and ease of use across your setup. The combination of large readouts, condensation resistance, and AS-1 bus interoperability sets it apart in the marine electronics landscape.

Practical insights for installation and use

• Plan the S400 Repeater as your cockpit hub for wind, speed, depth, and temperature, especially when you already use other NMEA-enabled instruments on board.
• Leverage AS-1 bus connections to synchronize readings across multiple S400 units and related devices, while using the NMEA strings to extend compatibility with third-party gear.
• Configure alerts to suit your vessel and conditions—alerts can trigger on-deck indicators to improve response time in challenging seas.
• Note the product’s update cycle reflected in its documentation (6-2024) to ensure you’re aligning with current spec and compatibility expectations.

Specification at a glance

The S400 Repeater provides a cohesive cockpit view by re-displaying data from wind, depth, speed, distance traveled, water temperature, and electronic compass direction. It reads data from NMEA sources and outputs data for further integration, while also exchanging information on the AS-1 AdvanSea bus for enhanced interoperability. Shipped from a local supplier and designed to deliver dependable readings across a range of marine conditions, this unit is a practical upgrade for any electronics-driven vessel.
