BBG-2003 Universal Conversion Engine

The Universal Conversion Engine is a stand-alone unit, which provides data format conversion of digital, analog, serial, step, synchro, and resolver signals.


  • Radar Systems (antenna azimuth)
  • Navigation Systems (gyrocompass, speedlog, course, pitch, and roll)
  • Industrial Processes (position, velocity)
  • Meteorology Instruments (wind speed and direction)
  • Many Others

The BBG-2003E/O-VME is a stand alone system which interfaces to several types of analog and digital inputs and outputs (I/O) in a 19-inch rack mount system and is factory configurable to customer requirements for easy field installation. An onboard microcontroller controls the processing of these signals to provide conversion to user requested outputs. An optional LCD display enables display of raw or converted data.

During power up or reset, an onboard microcontroller reads the configuration switch, configures the interface card, and provides all signals and controls necessary to read the desired interface, process and display the data, and output the converted information.

Serial Interfaces

Serial data interfaces use the standard National Marine Electronics Association(NMEA) message formats NMEA-0183. This I/O is available in RS-232, RS-422, RS-423, RS-485, or MIL-STD-188C protocols. Standard output update rate is once per second. Custom serial data formats and frequencies are available upon request.
