Chuck Thank you for the parallel port suggestion. I followed it up by opening the D-25 and reviewing the wiring. It looks very RS232 to me, the pin out I found is detailed in my 10 1314A Apr 22. That the punch and reader respond to RS232 input I think settles the issue - I was briefly optimistic ...

A lot of these CNC (I'm assuming that this Fanuc unit falls in that category) used the CL interface. Connector's the D-25. --Chuck
