Compatibility of the USB-OI16 to USB-PIO with OI16 

The USB-OI16 incorporates all functions in one device provided by the combination of a USB-PIO and 
OI16.  
Therefore, the USB-OI16 can serve as an alternative for this hardware combination. All previously 
used applications are fully compatible.
