Hi, I've been battling a weird problem today of not being able to acquire negative voltage values with my NI PCI MIO card. When executing the cmd demo program, for example, every time the input voltage is < 0, the acquired value shoots up to 63000 or so (max res for my card is 4096). I have my range set to 3 (bipolar +/-1V). when I set it to unipolar 0-5V, the negative values just give 0 and everything looks fine. Maybe my problem is hardware related, or I'm just missing something very simple because I'm very tired, but I am out of things to try. Please let me know if you have any suggestions or have experienced similar problems. Thank you, Naoko Kurahashi
