Does a square wave qualify as a digital signal to be given to the DAQ assistant for NI 9401?

Hi 

I m using ni 9401 with cDAQ 9172. I require a digital pulse train so that I can control the speed of motor by pulse width modulation. So can I supply a square wave using simulate signal option to the DAQ assistant? Does it qualify as digital as the NI 9401 is a digital I/O device.

Thank you for reading

Awaiting a reply.

I am stuck at same problem let me know if you have answer

The simulate signal puts out an analog signal.  But what you can do is use a comparison to change it into a boolean array.

Using the default settings for the square wave generation, I recommand converting the dynamic data into a 1D Array of scaler and then use Greater Than Zero? to change it into a boolean array.
