Help with Mesa 7I97T card CCW and CW

Can the 7I97T output pins be configured to generate CCW and CW signals instead of the standard PWM ±10V? I mistakenly purchased servo drivers that only accept CW and CCW inputs, so I'm seeking a solution

No, you would need a card with buffered 5V outputs for that.
A 7I96S would be a better choice if you don't need per axis encoders.\
or  7I95T  if you do need encoders.

You could add a daughter card to the 7I97T to get step dir outputs
say a mesa 7I85S or a generic parallel port breakout, like the
common "Mach 5 Axis breakout"
