Re: PWM Input?

You are correct that it is a digital PWM input. However, it is also requires a digital output on the same pin to trigger a distance measurement. The cRIO FPGA wasn't designed to handle this use case. There are many other ultrasonic sensors that would be easier to use, including digital ones where the request and the response are on different pins. Alternately, you could build a circuit to separate the two signals.
