Hi kalanyuz
Thanks for using NI Discussion Forums!
May I ask for more info about your setup?
When you say that the channels get mixed up, what exactly happens?(channels get switched, no voltage detected, etc.)
Does the same thing happen running a sample vi, or is it only with the datalogger?
Have you been using the USB-6211 with previous drivers?
Sorry to overwhelm you with questions but I'd appreciate if you could answer these questions.
Thank you,
