Data Converter Unit (DCU)

The data converter unit provides for the translation of avionics data formats, supporting cockpit flexibility needs in upgrade, control, and data recording applications.

BAE Systems has the engineering and production facilities to design and fabricate circuit card assemblies (CCAs), hardware modules, and software drivers to accommodate any aircraft and avionic sensor interface. Hardware modules and associated software drivers currently exist at BAE Systems for virtually every avionic sensor interface.
