General questions and apologies if the information is out there. I understand that when I specify a "rising edge" trigger, the task will trigger once a positive slope of voltage is detected. I am still unsure on how big that slope needs to be. I also wonder what voltage level Labview considers to be "high" and "low." In essence, I am wondering if specific numbers for rising edge slope and high and low voltage states are noted anywhere in the documentation or elsewhere. Would appreciate any insight people can provide.
