I have a stepper motor controller that requires a pulse output from my cRIO. The input for the pulse is tied high with a 20k ohm resistor on the driver and the rising edge of the pulse will cause it to actuate.
Essentially, I need an output that opens and closes a contact, rather than the sourcing output on the 9472 or the 3.3V TTL on the 9381. Can either of these cards handle that?
I'm able to get the driver to operate using a sourcing output (from 9472) into a mechanical relay but that isn't ideal for several reasons.
Running LV 2014 with a cRIO 9073 in scan mode. The 1ms scan rate isn't a problem for the speeds we are looking for out of this motor.
