How do I direct a VI to acquire data from a new interface?

[Michael_Golin]

Hello everyone,

I'm new to LabView and apparently the person who was most well versed in our department left a few months ago. I've recently purchased new USB interfaces (6212 mass terminal) for our computers. I have updated the software and the drivers on the first computer and I am now testing the interface with our existing VIs.

How do I instruct my VI to access the new interface rather than the old interface? Is this done through DAQmx?

thanks,

michael

You specify the device name in either MAX or in the physical channel control when using the DAQmx Create Virtual Channel. If the 6212 is the only DAQ device and there was only one DAQ device used by the old code, you may not have to change anything. The 6212 should appear as Dev1 so you need to find out what the old code was referencing. If it was also using DAQmx, then you job might be very simple.

I would recomend you first spend some time at the Getting Started with DAQmx to get an understanding of the basic principles.
