No.

This question comes up because users might be tempted to try to do the PID Ping Pong Ball Levitation experiment, from Engineering Projects with NI LabVIEW and Vernier (EPV, discontinued), using a DCU instead of a power amplifier to power the fan. This seems like it might be possible using the SensorDAQ PWM screw terminal line wired to a DCU. However, it is not possible to do PWM output from that screw terminal while simultaneously using a Motion Detector on the DIG port.

The reason this does not work is because the PWM screw terminal line is actually wired to two locations. It is wired to the screw terminal, but it is also wired to the DIG port (pin 2). When the Motion Detector is connected to the DIG port, this line is used to fire the Motion Detector’s Init line. This means the PWM screw terminal line is unavailable.

The only easy option for this experiment is to use the analog out screw terminal pin while simultaneously using the Motion Detector. This screw terminal pin can be connected to a Vernier power amplifier to control the fan. This is the method outlined in the book.
