Hello,
I am in the middle of converting a mill and ran out of inputs. I understand i could install another parallel port to gain more my question is how. I install the second port make sure i have the addresses right then what. Do i use another breakout board to connect to the mill. I see i could use pins 2-9 as inputs but how are they wired? Maybe a dumb question but i can't find any info on the topic.
Thanks for the help,
Dirk
