Rugged NMEA multiplexer for reliable data routing and seamless Raymarine ECS/Black Box radar integration in tough commercial marine settings.
The Raymarine Pathfinder Data Collection Unit 2 is a rugged NMEA multiplexer designed for seamless integration with Pathfinder ECS and Pathfinder Black Box Radar systems. Built on the Actisense PRO-NDC-1E2K platform, it bridges NMEA 0183 and NMEA 2000 networks, enabling reliable data routing across complex onboard systems. With five opto-isolated inputs, two ISO-Drive outputs, Ethernet streaming, and web-based configuration, it offers flexible, intelligent data management for non-SOLAS commercial vessels. RINA type-approved and IEC 60945 compliant, the DCU2 is engineered for dependable performance in demanding marine environments.
Pathfinder DCU-2 includes five OPTO-isolated NMEA 0183 inputs and two ISO-Drive™ outputs.
