© National Instruments Corporation 1-1 NI 783xR User Manual1IntroductionThis chapter describes the NI 783xR, the concept of the Reconfigurable I/O(RIO) device, optional software and equipment for using the NI 783xR, andsafety information about the NI 783xR.About the NI 783xRThe NI 783xR devices are R Series RIO devices with 16-bit analog input(AI) channels, 16-bit analog output (AO) channels, and digital I/O (DIO)lines.• The NI PXI-7830R and NI PCI-7830R have four independent AIchannels, four independent AO channels, and 56 DIO lines.• The NI PXI-7831R/7833R and NI PCI-7831R/7833R have eightindependent AI channels, eight independent AO channels, and 96 DIOlines.A user-reconfigurable FPGA (Field-Programmable Gate Array) controlsthe digital and analog I/O lines on the NI 783xR. The FPGA on the R Seriesdevice allows you to define the functionality and timing of the device. Youcan change the functionality of the FPGA on the R Series device inLabVIEW using the LabVIEW FPGA Module to create and download acustom virtual instrument (VI) to the FPGA. Using the FPGA Module, youcan graphically design the timing and functionality of the R Series device.If you only have LabVIEW but not the FPGA Module, you cannot createnew FPGA VIs, but you can create VIs that run on Windows or a LabVIEWReal-Time (RT) target to control existing FPGA VIs.Some applications require tasks such as real-time, floating-pointprocessing or datalogging while performing I/O and logic on the R Seriesdevice. You can use the LabVIEW Real-Time Module to perform theseadditional applications while communicating with and controlling theR Series device.The R Series device contains Flash memory to store a startup VI forautomatic loading of the FPGA when the system is powered on.
