At the start of a test the data channels are being randomly assign. I am using the DAQPad 6015 with NI Signal Express for Win XP. I am trying to monitor 8 differential voltages. The test data is written to an ASCII file and I do not know which data set belongs to which channel. I know this is not how the system was desgined to work, so either I am doing something wrong or this is a bug. I have only had this equipment for a little while so I assume it is an operator error. Any assistance is greatly appreciated.
