I am setting up my gantry router (XYYZA) with Mesa 7i92TH and having a problem getting my A axis to operate properly. I cannot rotate in both directions. I have a step on DB16 but nothing on direction (I assume DB17). Here is a copy of card configuration. Where is channel 4 direction?
Configuration pin-out:

14 1 IOPort PWM 0 PWM (Out)

Any settings in Pnconfg has no affect on any of these settings. I hope some one can help before I go nuts.
Thanks Jan
