Bridge Data Collection System// Bridge Data Collection NMEA to Modbus Multiplexer and Converter

Bridge Data Collection System designed exclusively for industrial marine application, receives every NMEA Signal of the Navigational Instruments and converts them to Modbus RTU in order to transfer collected data to ship’s Owner Office.

Bridge Data Collection NMEA to Modbus RTU Converter

SELMA Bridge Data Collection Unit implements data acquisition of every NMEA IEC 61162-2 Signal interfaced to Existing Voyage Data Recorders (VDRs) or directly from Navigation Instruments such as DGPS, Anemometer, Gyro Compass, Speedlog, Echo Sounder and Autopilot, performing multiplexing and conversion into MODBUS RTU / Ethernet data signal. Collected data is made available to the ship’s network and shore office for recording, reporting, data analysis, voyage planning, routing history and any other post processing application.
