NMEA Distribution Box with up to 15 NMEA outputs.

The NMEA distribution box KMD-550 is able to take two independent NMEA 0183 inputs and transmit a NMEA 0183 output to up to 15 devices. This allows digital heading data (ship’s heading) or other NMEA 0183 data of individual NMEA 0183 signals to be relayed to multiple devices.


  • Twelve RS422 outputs, three RS232 outputs and one speed closure signal (can be configured to Fifteen RS232 and one speed closure signal)
  • Power supply isolated
  • High speed baudrate up to 38400
  • Input signal isolated
  • Every channel output is isolated
  • Can be used as independent NMEA distribution box
