I am using a USB-6501 device to get a trigger input on a conveyor. From what I have been reading the counter is more efficient at this task. Could anyone explain what is different about a counter I/O vs a digital I/O?
A counter measures period, frequecy, and time delay. A DIO measures state. What kind of measurement are you trying to perform?
I am trying to determine the time between triggers (ms) to ensure the analysis is complete before the next image is captured.
