KEC5021 is an USB input and output module, by which a operation panel for a compute based
    system can be designed simply at low cost. 
    KEC5020 connects with PC by USB port with plug-and-play USB connectivity. No special USB
    driver is requests. A SKD software package includes DLL library for output control, verification 
    application and development samples.
