we want to be able to record a digital input from a machine to a computer (serial, parrell, usb, doesnt matter) and record an occuance of this digital input into excel (like a counter) we can make the digital output from the machine anything from 2.5V to 25V. this is for a custom cutting machine that we want to count the cuts. our engineer can propose a digital output for us it is just knowing what device we need between the machine and the pc.
any help would be greatly appriciated. if any of this makes sense.
