Sharon_ Posted July 25, 2011 Report Share Posted July 25, 2011 Hi, I have just bought a NI USB (http://sine.ni.com/nips/cds/print/p/lang/en/nid/201630) 6501 module from NI. I don't know where to start. It is not listed under VISA devices.But in MAX explorer it shows 'Dev1'. Do I need to use DAQmx to access the device? Sorry, this is first time I am using these kind of external hardwares. Sharon Quote Link to comment
jgcode Posted July 25, 2011 Report Share Posted July 25, 2011 Did you check the manual? - DAQmx will definitely work. The drivers are free and should be included with the device or can be downloaded from NI's website. Quote Link to comment

Wire Warrior Posted July 25, 2011 Report Share Posted July 25, 2011 Sharon, Check your connection there. I think you need to initialize the task and then connect the task reference to the acquisition VI. Jason Quote Link to comment
Mark Smith Posted July 25, 2011 Report Share Posted July 25, 2011 This is one of those places where using the DAQ Assistant (on the LabVIEW Function Palette) is sort of useful. If you drop the assistant on block diagram, it will guide you through creating a simple DaqMx VI using your new card. You can then convert the assistant to code and see what had to happen to open and talk to your card. A caveat: The DAQ Assistant (imho) does not make code that should be used in anything that remotely resembles production code. Just use it as a learning tool and then re-write the DaqMx code to fit your particular application. Mark Quote Link to comment
