Stepper Cards Zero Position

[Tripacer]

After studying the stepper card I am still not clear if the card has a hardware zero location sensor input. Many use a small optical switch to sense the location of the motor shaft at startup. How do they handle this important function?

If you are talking about the OC card, just as you described. with an optical sensor.

As described on page 5 and 6 of their manual that can be found here:
