Need 1 more Input
« on: September 22, 2012, 08:13:48 AM »
Hello World,
I'm one input short for a project I'm working on.   Given the fact that the modern day parallel port can use pins 2 - 9 as either input or output why are the Mach inputs limited to pins 10 - 13, and 15?
Your help is appreciated, thank you.

If you add a second port you can set that up to pins 2-9 as Inputs.
First port however can not be set that way, probably because that would only leave 4 outputs and as you need 2 per axis then the thinking would be you couldnt set up a normal machine with them.
