By far, the most common problem with getting the SensorDAQ up and running has to do with the NI-DAQmx USB driver software.
Here are some tips for troubleshooting DAQmx, as well as some other issues that commonly present problems:
Did you install the DAQmx software?
1. You can see the currently installed version of NI-DAQmx by running the Measurement & Automation Explorer (MAX) and then expanding the Software category. MAX is installed with DAQmx, so if you do not have this software then you should install DAQmx.
2. Connect the USB cable to SensorDAQ and attach the other end of the USB cable to any USB port on your computer. If the NI-DAQmx driver software is properly installed, the computer should provide a Found New Hardware message and the SensorDAQ LED next to the USB cable port on the SensorDAQ should be blinking. If not, install DAQmx.
3. Open one of the SensorDAQ example VIs found in the LabVIEWexamples directory. Does it open without warnings? If it opens but gives a lot of warnings, it cannot find DAQmx subVIs, install DAQmx.
Did you install DAQmx after installing LabVIEW?
LabVEW must be installed first. If you installed the DAQmx before you installed labVIEW, reinstall DAQmx. If you are not sure, try reinstalling DAQmx.
Are you using a version of DAQmx that is compatible with your version of LabVIEW?

Is your USB cable or computer USB port okay?
Try another cable and a different USB port.
Did you install the SensorDAQ files?
1. If you are using a version of LabVIEW that is not the Education Edition, you will need to install the SensorDAQ files.
2. Can you find the SensorDAQ examples in the LabVIEWexamplesVernier directory? If not, then you must install the SensorDAQ files.
Are you using a Mac computer?
The DAQmx driver for SensorDAQ does not work on Mac computers.
How to get NI-DAQmx software
Option 1. NI-DAQmx is shipped with LabVIEW as part of the Device Driver DVD.
Option 2. The NI website, ni.com. Do a search for DAQmx or go to the NI Drivers page in Support.
