The USB KeyBox was specially developed for use in industrial environments. The power supply and PC connection are provided via a USB mini plug from Buckaneer (screwable).

An address can be assigned to the KeyBox via the USB connection or it can be addressed via broadcast. The LEDs under the buttons can be individually controlled the status can be displayed to the operator or an input request can be displayed. The data exchange always consists of 64 bytes (send/receive) and always has the same structure:
Address, command, length and data.
