NDC-2 NMEA MULTIPLAYER

 

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
