Actisense NDC-4-AIS-USB NMEA0183 Multiplexer

Multiplex or Autoswitch up to 4 NMEA0183 devices to your PC, Chart-plotter, Radar, Autopilot, AIS and more, with NMEA 0183 HS compatibility and ISO-Drive

The NDC-4-AIS-USB model is one of five NDC-4 versions available from Actisense.

The Actisense NDC-4-AIS-USB model version is pre-configured for AIS and USB connection and is a next-generation NMEA Combiner / Multiplexer that has full isolation on all inputs and all outputs.

Using the ISO-Drive Actisense technology, ground loops are now a thing of the past.

Can Combine or Autoswitch up to 4 NMEA0183 devices, plus filter out any problematic or unwanted NMEA sentences.

• Full galvanic Opto-isolation on NMEA 0183 inputs
• Full galvanic isolation on NMEA 0183 / ISO-Drive outputs
• Configurable Port Baud rates and priorities

• Completely removes the need for isolated power supplies - as the NDC-4 creates a full 2500v isolation barrier between its inputs and each of its ISO-Drive outputs
• Enables the vessel owner complete access to all NMEA data sources, instead of the standard one device
• Any problematic or unwanted NMEA sentences can be filtered out / blocked, to help intelligently reduce the NMEA data to a manageable amount and prevent data loops
• Each NMEA input device is Opto-isolated from all other NMEA devices in the system
• Significant reductions in installation cost (from reduced cable lengths and requiring only one NMEA cable to be routed around the bridge to supply the multiplexed NMEA data)
