I am reading in 28 differential analog inputs and when everything is plugged in all the values are showing up correctly, but when I disconnect one of the inputs it takes a form of the value of the input prior to it. In other words if I unplug input 15 and modify the input for 14, 15 will change with it and be proximate, or the same, to its value when it should be at about 0 and staying there. I checked the voltage levels going into the breakout boards for the pci-6033e and they are about 0 so my guess is that it is something in the software that I am not doing correctly. This is a big issue because if a cable gets unplugged accidentally then there will still be data showing up for that input. Anyone know anything about something like this happening or any idea why it is doing this?
