The National Instruments PCI-7811R features user-defined, onboard processing for complete flexibility of system timing and triggering. Instead of a fixed ASIC for controlling device functionality, R Series intelligent DAQ uses an FPGA-based system timing controller to make all 160 digital I/O lines configurable for application-specific operation. The FPGA chip is configured by creating LabVIEW block diagrams with the LabVIEW FPGA Module. Your block diagram executes in the hardware, giving you direct, immediate control over all I/O signals to deliver high-performance capabilities such as:

- Complete control over the synchronization and timing of all signals and operations
- Custom onboard decision making that executes with hardware-timed speed and reliability
- Digital lines individually configurable as inputs, outputs, counter/timers, PWM, flexible encoder inputs, or specialized communication protocols

With intelligent DAQ and LabVIEW FPGA, you can configure user-defined hardware for a wide variety of applications, such as custom digital data acquisition, high-speed waveform generation, sensor simulation, hardware-in-the-loop (HIL) test, digital protocol emulation, bit error rate testing, and other applications that require precise timing and control.

Recommended Accessories
The SHC-68-68-RDIO cable is designed and shielded specifically for the DIO connectors on R Series devices for improved signal integrity when connected to terminal blocks or the cRIO-9151 R Series expansion chassis.

Low-Cost, High-Performance Signal Conditioning for R Series Intelligent DAQ
The NI cRIO-9151 R Series expansion chassis connects directly to any digital connector on R Series devices and houses up to four C Series I/O modules for low-cost signal conditioning, analog I/O expansion and direct connectivity. For more information on I/O availability, please reference the related links below.
