Fanuc PPR - Paper Tape Punch, Printer and Reader : Not quite working

[Martin Bishop]

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 ...

Are you certain that the interface isn't wired for current loop?  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.
