Rugged NMEA 0183 multiplexer with ECDIS/radar integration, enabling smart data routing and filtering in complex marine networks.
The Raymarine Pathfinder Data Collection Unit (DCU) is a rugged, intelligent NMEA 0183 multiplexer built on the Actisense PRO-MUX-2 platform. Designed for seamless integration with Raymarine Pathfinder ECDIS and Pathfinder Radar CAT-1, CAT-2, and CAT-3 systems, it delivers reliable data routing across complex bridge networks. With eight OPTO-isolated inputs, six ISO-Drive™ outputs, and advanced filtering capabilities, the DCU ensures precise control of navigation and sensor data. A web-based configuration interface, diagnostic LEDs, and stainless-steel housing make it ideal for commercial vessels, superyachts, and government craft requiring robust, type-approved data management in demanding marine environments.
Pathfinder DCU includes eight OPTO-isolated NMEA 0183 inputs and six ISO-Drive™ isolated outputs.
