I've got the buttons installed on a panel on my machine and I've run wires to the parallel port input pins with the 470 ohm resistors like the docs say.  I dont know how to make them push the buttons on the screen though.  How do I link pins to pushing screen buttons like "run" "stop" and "zero x" ?

Thanks!

Hey Mike,
    You can set them up as triggers in ports and pins, inputs. Then go to config, system hotkeys and assign them an OEM code. I hope the pics help.

where do I get the codes from for each button on the display?

I think most of them are listed in the wiki. http://www.artsoftcontrols.com/MachCustomizeWiki/index.php?title=Main_Page Go down to section 9, OEM buttons.
