I have a NI USB-6366 with BNC input.
It works fine, but am worried that the trigger cable can turn on the power on lamp. The voltage on the pulse generator for the trigger also changes from 0-5 V to 2.5-5 V when the trigger cable is connected to a PFIn input. I suspect my problems has to do with grounding, but I don't understand what I should do, or if this really is a problem.
