I have searched the knowledge base a learned that the floating voltages that I am seeing on my graph when nothing is connected to the physical channel is normal for NI devices. So is there a way to programatically detect if there is nothing connected to the physical channel?? I am using a cDAQ9184 with a 9205 AI module. I'd like to disable my wafeformgraph or the wafeformplot of the graph via coding if there is nothing connected to the physical channel in question.
This is more of a question about the underlying capabilities of the NI-DAQmx driver. You may receive better responses if you post here: forums.ni.com/t5/Multifunction-DAQ/bd-p/250
