Data Acquisition Toolbox™

Troubleshooting Your Hardware

This appendix describes simple tests you can perform to troubleshoot your data acquisition hardware. The tests involve using software provided by the vendor or the operating system (sound cards), and do not involve using the Data Acquisition Toolbox software. The sections are as follows.

• Advantech Hardware

• Measurement Computing Hardware

• National Instruments Hardware

• Sound Cards

• Other Things to Try

To accurately test your hardware, you should use these vendor tools to match the requirements of your data acquisition session. For example, you should select the appropriate sampling rate, number of channels, acquisition mode (continuous or single-point), and input range. If these tests do not help you, then you might need to register the hardware driver adaptor or contact The MathWorks for support. Contact information is provided in Contacting The MathWorks as well as in the beginning of this guide. If the problem is with your hardware, then you should contact the hardware vendor.

Note that if you cannot access your board using the vendor's software, then you will not be able to do so with the Data Acquisition Toolbox software.

Note   To see the full list of hardware that the toolbox supports, visit the Data Acquisition Toolbox product page at the MathWorks Web site www.mathworks.com/products/daq.
