DM1210N - Data Multiplexer


The DM1210N is a 12 input, 10 output, RJ45 Network interface data multiplexer designed to assist with the total integration of electronic equipment in the wheelhouse. With an increase in quantity and types of equipment generating serial data, it is necessary to combine and filter the data. The DM1210N gives full dc isolation between the input supply and ground, inputs and outputs.


  • Furuno CIF conversion.
  • Filtering of NMEA sentences by Talker or Formatter for each input and output
  • Flexible multiplexing from one port to any other
  • NMEA0183 In or Out talker modification
  • NMEA/CIF depth sentences from trigger and bottom or JRC trigger/clock/data
  • AD10 data from NMEA, VTG, VHW, HDG, HDM, HDT, etc
  • 100, 200, 400 or 800 PPNM to VTG/VHW
  • Alarm outputs (2) when defined inputs received, ie. predefined depth, waypoint, DGPS, etc
  • User selectable mode for Baud rate, Stop bits, Parity, Data bits, Start/Stop characters
  • Baud rates up to 115200 enabling fast data transfer
  • Automatic prioritised Dual/Tri Input switching, GPS Sounder, Heading etc
  • NMEA sentence Rate control, Increase/Decrease
  • Many other conversions from customers request


Device configuration is done using the DMxxConfig program supplied on your computer connected to the DM44 via the Ethernet port.
