NDC-2 NMEA MULTIPLEXER

The NDC-2 is no longer in production. Please see the current NDC-5 model.

The Actisense NMEA Multiplexer / Combiner allows connection of up to four NMEA (National Marine Electronics Association) inputs to be multiplexed/combined in to one NMEA output.

across entire Actisense range as standard

The Actisense NMEA Multiplexer / Combiner allows connection of up to four NMEA (National Marine Electronics Association) inputs to be multiplexed/combined in to one NMEA output.

This approach offers these major advantages:

Electrical spike protection is provided as standard on all four input channels using opto-isolators. This protects any connected equipment from most system faults; a particularly valuable benefit as equipment requiring the most data, such as a PC or chart plotter, is often the most expensive to repair or replace.

The NDC-2 Data Multiplexer contains highly intelligent software that manages the multiplexing and filtering operation, allowing every input to have a chance of its data reaching the combined NMEA output. Tested up to and beyond a combined 300% loading of the four inputs.

  • It enables the vessel owner complete access to all NMEA data sources, instead of the standard one device
  • Each NMEA input device is Opto-isolated from all other NMEA device in the system
  • Any NMEA data not required can be easily filtered out to reduce the total amount of NMEA data in the system
  • Each input and output baud rate can be changed to match the requirements of connected devices

    Hi Tony, thanks for your comment. What information are you looking for? Send us an email to marketingcomms@actisense.com and we’d be happy to assist!

    This is the best looking compact N2K tee with power feed. Better than building your own with individual T’s that ends up being over a foot long just to get the same amount of ports.

    I like your products, but I’m not sure who your representatives are in Venezuela. We usually purchase them from your distributors in Miami. At Vzla Marine Group, we use them for our facilities and would like to add your products to our sales catalog.
    If you are interested, please contact us.

    Megan @ Actisense

    Hi Vicente, thank you for your review! We have passed on your details and a member of our sales team will reach out to you directly. Thank you.
