The NI M and X Series Terminal Board connects an NI myRIO device to Quanser control plants. It has two analog inputs, two analog outputs, and two single-ended encoder input interfaces. You can access all inputs and outputs simultaneously using unbuffered single-point reads and writes, which is ideal for real-time control. The convenient set of I/O and connectors minimizes setup time and connection errors, so students can concentrate on learning the fundamentals of hardware interfacing and control.
Same as the physical Rotary Servo Base Unit, the virtual system features a DC motor that drives a smaller pinion gear. This gear is fixed to a larger middle gear that rotates on the load shaft. The position of the load shaft is measured using a high-resolution optical encoder or a potentiometer.
