question for potential Gecko 320/340 users

I am in the process of finalizing the design for an
interface board that provides, among other things,
an isolated, buffered feedback from the Gecko 320/340
step-servo drivers. Since this signal is different
from other feedback and cannot be interchanged with
plain contact closure inputs, where should it show
up on the parallel port?

It would be useful to hear from users of EMC, Master5,
TurboCNC, CNCPro, MaxNC, and any other systems. If
you prefer, or if you have trouble posting to Yahoo,
you can reply to stevesng (at) newsguy (dot) com.

Thanks,
Steve Stallings
