I am wanting to use a NI-9209 cDAQ module to take some differential measurements. I will not be using all of the differential channels on the device and I have some other single-ended measurements that I need to do as well. Can differential and single-ended inputs be done on the same module, assuming the proper wiring connections are made? For example, could I do a differential measurement using AI0/AI8 and then do a single-ended (RSE) measurement on AI10? Is the differential/single-ended configuration at the module level or is each channel configurable?
