The following web sites provide information regarding the PC’s parallel port, including pin-outs, signal
names and useful data for software control of the parallel port:

If the previous links do not work, go to http://www.pmdx.com (our main web page), click on the
“handy CNC information” link and then look for the links to parallel port information pages
Note that these web links were accurate as of the printing date of this manual. While we expect that
these two sites will remain available at these addresses, it
is
possible that they will move or disappear.

Status Input Connector (J8)
The status input connector provides wire clamp screw terminal connections for all of the PC parallel port
status signals except for pin 10. Pin 10 is used to indicate emergency stop and fault conditions to the PC.
See section 3.5.2 for more information on the emergency stop input.
