General Mach Discussion / Pin Test
« on: September 04, 2016, 11:57:56 PM »
Hi group, had a quick clarification. I'm trying to set up my Mini CNC and was checking the voltage on my 25 pin port in back of my computer. According to what I have read so far I should be able to read apx 5 volts when pressing the arrow keys. I just tested my top row 1-13 right to left and all are reading 5+ volts without touching any arrows. Any ideas?
A quick addition, my bottom row 14-25 left to right is reading pin 14-22 is reading 00 and pins 23-25 read 5+ volts with no arrows pressed.
Thanks Wayne
