Actisense PRO NDC 1E NMEA 0183 Multiplexer 5 Inputs 2 ISO Drive Outputs

The Actisense PRO NDC-1E is a rugged, Type Approved NMEA 0183 multiplexer designed to bring order, reliability, and intelligent routing to your marine data networks. With five opto-isolated NMEA 0183 inputs and two ISO-Drive outputs, it protects every connected instrument while delivering clean, prioritized data to the devices that need it most.

Why this matters on the water

Marine electronics teams rely on accurate, timely data from multiple sensors and controllers. The PRO NDC-1E tackles the toughest challenges: conflicting sentence streams, varying baud rates, and busy networks. By intelligently managing NMEA 0183 traffic, it ensures critical information—GPS, depth, wind, and more—reaches the right display or autopilot without interruption.

Key features and what they mean for you

• Five OPTO-Isolated NMEA 0183 inputs plus two ISO-Drive outputs protect your instruments from common electrical faults and noise while ensuring clean, dependable communication.
• Dedicated bi-directional serial port with full ISO-Drive isolation for flexible routing—use the serial link as an additional input or output as your network grows.
• Ethernet and serial connectivity with NMEA 0183 streaming over Ethernet, enabling seamless integration with existing networked systems and chartplotters.
• Configurable baud rates (38400 and 4800) so legacy devices and modern instruments can coexist on the same multiplexer without slowdowns or data loss.
• Sentence-level filtering to block unnecessary data on specific outputs, reducing network bandwidth usage and avoiding clutter on your displays.
• Two independent Autoswitch virtual inputs with priority for automatic failover and clean primary/secondary/tertiary routing of critical data.
• Web-based configuration—set up and tune the device from any browser, with no need for dedicated software or operating system compatibility concerns.
• RINA Type Approved device, suitable for leisure boats, commercial vessels, and class/type installations, offering peace of mind and regulatory alignment.
• Diagnostics at a glance via multiple LEDs for quick status checks, plus optional DIN rail mount for tidy, space-conscious installations.
• Future-proofing and firmware updates keep the device current as your network grows or evolves.

Use cases that prove its value

• Consolidating multiple NMEA 0183 sensors (GPS, wind, depth, AIS, etc.) into a single, well-managed data stream for chartplotters and radar.
• Integrating legacy 38400 baud instruments with modern devices without swapping hardware, thanks to configurable baud rates and rate conversion capabilities.
• Providing a reliable primary data path with automatic failover to secondary sources, reducing the risk of data outages during critical maneuvers.
• Streaming NMEA 0183 data over Ethernet to networked displays and onboard systems, enhancing information visibility across the vessel.
• Complex installations where isolation and protection are essential to preserve instrument reliability in harsh marine environments.

Why Actisense stands apart

• Proven reliability and installer-friendly design—rugged construction and a straightforward web UI streamline deployment on boats of all sizes.
• Comprehensive protection through ISO-Drive and opto-isolation, safeguarding both power and data integrity.
• Advanced data management features—baud rate flexibility, sentence filtering, and auto-switching—solve real-world routing challenges without added complexity.
• Regulatory confidence with Type Approved certification, ensuring compatibility with marine standards and installation requirements.
