The National Instruments PCI-6221 (37-Pin) DAQ board offers a cost-efficient solution for OEM customers because of its 37-pin D-Sub I/O connector. The D-Sub connector provides compatibility with other standard D-Sub accessories, including low-cost direct-mount terminal blocks such as the NI CB-37F-LP. For applications requiring higher speeds and increased accuracy, consider the high-speed M Series for 5X faster sampling rates and the high-accuracy M Series for 4X better resolution.

Low-cost M Series devices incorporate advanced features such as the NI-STC 2 system controller, NI-PGIA 2 programmable amplifier, and NI-MCal calibration technology to increase performance and accuracy. To learn more about M Series technologies, device specifications, and information on recommended cables and accessories, please refer to the data sheet and specifications.

Driver Software
M Series devices work with multiple operating systems using three driver software options including NI-DAQmx, NI-DAQmx Base, and the Measurement Hardware DDK. 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 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.x, LabWindows™/CVI 7.x, or Measurement Studio 7.x; or LabVIEW with the LabVIEW Real-Time Module 7.1.
