|New NI M Series Data Acquisition Board Lowers Connectivity Costs by 80
Original equipment manufacturers (OEMs) and engineers
interested in low-cost I/O connectivity and custom cabling now can take advantage of 80 percent lower connectivity
costs with the new National Instruments PCI-6221 (37-Pin) multifunction data acquisition (DAQ) board. While the
PCI-6221 (37-Pin) DAQ board includes the technologies featured on other low-cost M Series DAQ devices, including the
NI-STC 2 system controller, the new board uses a 37-pin D-Sub connector for commercially available I/O connectivity.
Because basic shielding connectivity solutions for 37-pin devices are now available at prices four to five times
lower than 68-pin devices, engineers can take advantage of low-cost connectivity while integrating high-quality NI
data acquisition boards.
OEMs face unique challenges such as needing to
get products to market quickly and creating affordable applications for large deployment. The new PCI-6221 (37-Pin)
DAQ board offers a cost-efficient solution because of its 37-pin D-Sub I/O connector and its compatibility with
other standard D-Sub accessories, including low-cost direct mount terminal blocks such as the NI CB-37F-LP. The
versatile measurement and control capabilities offered in the PCI-6221 (37-Pin) DAQ board also make it especially
useful for machine builders, control systems, design verification and test.
The new PCI-6221
(37-Pin) DAQ board delivers the same analog input, analog output and counter/timer features as the existing NI
PCI-6221 DAQ board but with a standard, low-cost connector. These features include 16 analog inputs at 16 bits and
250 kS/s, two analog outputs at 16 bits and 833 kS/s and two 32-bit counter/timers at 80 MHz. The PCI-6221 (37-Pin)
also provides 10 bidirectional digital I/O lines – two of which are correlated at rates up to 1 MHz.
The PCI-6221 (37-Pin) DAQ board ships with the full suite of NI measurement services software, including tools
and drivers for connecting virtual instrumentation software with NI measurement and control hardware. NI measurement
services software, built around NI-DAQmx driver software, includes intuitive application programming interfaces,
configuration tools, rapid I/O assistants and professional tools to help engineers reduce system setup and
configuration time. NI data acquisition products also work with application software, including NI LabVIEW,
LabWindows/CVI, SignalExpress and Measurement Studio for Visual Basic, C++ and .NET, and are supported on standard
operating systems, including Linux, Mac OS X and Windows XP.
