May 31, 2005 – National Instruments today announced the NI PCI-6225 and PXI-6225, the newest members of the low-cost M Series data acquisition (DAQ) family that extend available I/O functionality to include 80 16-bit analog input channels with sampling rates up to 250 kS/s. The new NI 6225 devices provide the most analog input channels of any NI multifunction DAQ devices and are ideal for applications such as data logging, control and sensor measurements.In addition to the 80 analog input channels, the NI 6225 devices deliver all of the NI M Series improvements, including more I/O, performance and value. The new NI-MCal technology in these devices increases accuracy across the entire measurement range by performing a self-calibration at each input range and compensating for nonlinearity error. The NI-STC 2 system controller chip delivers digital I/O and timing capabilities previously unavailable with plug-in DAQ devices, such as timed and correlated digital I/O. The chip also provides 32-bit counter/timers with quadrature encoder inputs and debouncing filters, as well as six DMA channels for dedicated data paths to the PC processor for all I/O operations.The NI PCI-6225 and PXI-6225 include two analog output channels, 24 digital I/O (DIO) lines, hardware-timed digital I/O at rates up to 1 MHz on eight DIO lines and two 80 MHz, 32-bit counter/timers. NI ships both devices with its measurement services software, a collection of tools and drivers that connects virtual instrumentation software, such as National Instruments LabVIEW, with NI hardware for measurement and control. 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.National Instruments DAQBy integrating commercially available silicon and bus technologies with innovative designs, NI data acquisition products continue to improve measurement speed and accuracy while reducing costs for engineers and scientists. NI data acquisition devices are available on the most widely used buses and work with the industry’s most popular operating systems such as Windows, Linux and Mac OS X. About National InstrumentsNational Instruments is a technology pioneer and leader in virtual instrumentation – a revolutionary concept that has changed the way engineers and scientists in industry, government and academia approach measurement and automation. Leveraging PCs and commercial technologies, virtual instrumentation increases productivity and lowers costs for test, control and design applications through easy-to-integrate software, such as NI LabVIEW, and modular measurement and control hardware for PXI, PCI, USB and Ethernet. Headquartered in Austin, Texas, NI has more than 3,400 employees and direct operations in nearly 40 countries. In 2004, the company sold products to more than 25,000 companies in 90 countries. For the past six years, FORTUNE magazine has named NI one of the 100 best companies to work for in America. For more information, Contact National Instruments or visit their web site at
