Actisense PRO NDC-1E2K NMEA 0183 Multiplexer NMEA 2000 Gateway

On the water, you don’t want data bottlenecks or mismatched interfaces slowing you down. The Actisense PRO NDC-1E2K is a purpose-built solution that seamlessly bridges legacy NMEA 0183 devices with modern NMEA 2000 networks while delivering data reliably over Ethernet. It’s more than a multiplexer—it’s a robust gateway designed for real-world marine environments where every sentence matters.

Why the PRO NDC-1E2K stands out

• Five opto-isolated NMEA 0183 inputs provide galvanic isolation to protect connected sensors from noise, surges, and fault conditions—crucial when mounting near high-current devices or antennas.
• Two ISO-Drive NMEA 0183 outputs deliver safe, isolated transmissions to display units, plotting devices, or exhibitors without compromising other gear on the network.
• Built-in NMEA 2000 connectivity means you can directly forward data to an NMEA 2000 backbone without adding a separate gateway, simplifying wiring and reducing failure points.
• Ethernet streaming for NMEA 0183 and NMEA 2000 data enables modern systems, tablets, chartplotters, and onboard servers to access live data without extra converters.
• Automatic baud-rate matching ensures 38400 and 4800 baud devices operate together through the same multiplexer, eliminating manual reconfiguration.
• Sentence-level filtering lets you selectively block or pass specific sentences to outputs, dramatically reducing bandwidth usage on busy networks.
• Web-based configuration means setup is quick and OS-agnostic—no special software required, just a browser on any device.
• Bi-directional serial port enables two-way communication between legacy equipment and newer systems, opening pathways for data sharing that used to require multiple adapters.
• RINA Type Approved and rugged stainless steel housing provide marine-grade reliability for leisure boats, commercial vessels, and Type-approved installations.
• Diagnostic LEDs and status indicators offer clear at-a-glance health checks, so you can spot issues before they impact navigation or monitoring.

What you can achieve with the PRO NDC-1E2K

Imagine integrating a fleet of classic NMEA 0183 sensors (wind, depth, radar or AIS) with a modern NMEA 2000 backbone and an onboard Ethernet network. The PRO NDC-1E2K does the heavy lifting—routing data where you need it, filtering out noise, and ensuring critical information reaches the devices that rely on it. The result is a cleaner network with fewer dropped sentences and improved overall situational awareness.

Ideal use cases

• Small to mid-size sailing and commercial vessels that maintain a mix of legacy sensors and modern NMEA 2000 equipment.
• Marinas, inspection vessels, and research boats that require reliable data routing with type-approved hardware for regulatory compliance.
• Systems where you want to stream NMEA data to Ethernet-enabled displays, PCs, or cloud-connected monitoring tools.
