Interface Unit .
The interface between the units and the user's computer is provided by the Interface Unit. This conditions the raw data from the sensors, digitises the data and transfers it to the computer using the USB interface. It also includes a sophisticated three-phase inverter for providing accurate motor-speed control, and a second motor-drive output, all under software control.
