NI-DAQmx Versus Traditional NI-DAQ Drivers

National Instruments provides two drivers for accessing their hardware. Data Acquisition Toolbox software supports both:

  • Traditional NI-DAQ
  • NI-DAQmx

    [note]The Traditional NI-DAQ adaptor will be deprecated in a future version of the toolbox. If you create a Data Acquisition Toolbox™ object for Traditional NI-DAQ adaptor beginning in R2008b, you will receive a warning stating that this adaptor will be removed in a future release. See the supported hardware page at www.mathworks.com/products/daq/supportedio.html for more information.[/note]

    Some older National Instruments devices require the Traditional NI-DAQ driver. Many of the newest National Instruments devices, such as the M-series, require the NI-DAQmx driver. However, many of the more popular National Instruments devices, such as E-series and S-series, can be used with either driver. To find out which driver your hardware requires, see the NI-DAQmx release notes at the National Instruments Web site, http://www.ni.com.

    If your hardware can use either driver, you should choose the NI-DAQmx interface. If you have a mix of hardware that cannot all use the same driver, you can install both drivers to access your hardware. Any device that supports both drivers will appear twice in the results of daqhwinfo('nidaq'); you should access these devices from the Traditional NI-DAQ interface.
