    NDCU - Navigation Data Computing Unit

    NDCU - Navigation Data Computing Unit is a universal device to receive and transmit RS422 signals such as NMEA 0183, Course Bus or other similar serial protocols with baud rate up to 115200 bps. The device is equipped with four independent serial inputs and four independent serial outputs, USB port which can be used not only for configuring the device but also for listening of the signals, and a fully configurable relay.

    Depending on the software uploaded by the user it allows to simple manipulate, filter, combine NMEA strings, making calculations and changing NMEA talkers or even protocols!


    • Multipurpose, flexible device
    • Simple and compact design
    • Easy installation on the DIN rail
    • Each NMEA input is separated from other connected NMEA devices
    • Four inputs with separately configurable baud rate
    • Four outputs with two channel buffers – so two receivers can be safely connected to each output
    • Standard USB port for programming the device or listening signals
    • Fully configurable relay (alarm, BNWAS reset or any other purpose)
    • Software upload by USB port and standard PC computer
