The National Instruments USB-6225 is a USB high-performance M Series multifunction data acquisition (DAQ) module optimized for superior accuracy at fast sampling rates. The NI USB-6225 is ideal for applications such as high-channel-count data logging and for sensor measurements when used with NI signal conditioning.

The USB-6225 is designed specifically for mobile or space-constrained applications. Plug-and-play installation minimizes configuration and setup time, while direct screw-terminal connectivity helps keep costs down and simplifies signal connections.

This module also features the new NI signal streaming technology, which gives you DMA-like bidirectional high-speed streaming of data across USB. For more information about NI signal streaming, check the Resources tab.

Each module also features an OEM version. Check the Resources tab or use the left navigation to get pricing and technical information.

Driver Software
NI-DAQmx driver and measurement services software provides easy-to-use configuration and programming interfaces with features such as DAQ Assistant to help reduce development time. Browse the information in the Resources tab to learn more about driver software or download a driver. M Series devices are not compatible with the Traditional NI-DAQ (Legacy) driver.

Application Software
Every M Series data acquisition device includes a copy of NI LabVIEW SignalExpress LE data-logging software, so you can quickly acquire, analyze, and present data without programming. In addition to LabVIEW SignalExpress, M Series data acquisition devices are compatible with the following versions (or later) of NI application software – LabVIEW 7.1, LabWindows™/CVI 7.x, or Measurement Studio 7.x. M Series data acquisition devices are also compatible with Visual Studio .NET, C/C++, and Visual Basic 6.
