Issue Details

Is it possible to have a single DAQmx task which combines both Differential and Single-Ended Measurements?

Solution

Yes, this is possible. To do this you need to call the DAQmx Create Virtual Channel.vi multiple times for each configuration. Using this method, you can combine different input terminal configurations and measurement types (thermocouples, strain gauges, etc...) within a single task as shown below.

Additional Information

The Multiple Input Configurations in a Single Task example demonstrates this method. 
Terminal Input Configuration can also be changed with a property node .
