The NI PXI-7853R multifunction R Series intelligent data acquisition (DAQ) module features a user-programmable FPGA chip for onboard processing and flexible I/O operation. You configure all analog and digital functionality using NI LabVIEW graphical block diagrams and 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 that are individually configurable as inputs, outputs, counter/timers, pulse-width modulation, flexible encoder inputs, or specialized communication protocols
Multifunction NI R Series intelligent DAQ devices feature a dedicated analog-to-digital converter (ADC) per channel for specialized functionality. Common examples include custom discrete and analog control, sensor simulation, rapid prototyping, hardware-in-the-loop (HIL) test, digital protocol emulation, and other applications that require precise timing and control.
Required Software
This product requires the LabVIEW FPGA Module 8.6 or later and NI-RIO 3.0 or later driver software.
New Virtex-5 FPGA
The new Virtex-5 FPGA architecture is optimized to execute faster and more efficiently using single-cycle timed loops in LabVIEW FPGA. This means you can optimize more LabVIEW FPGA code to fit within Virtex-5 FPGAs and execute more operations per clock cycle.
Recommended Accessories
The NI cRIO-9151 R Series expansion chassis connects directly to any digital connector on R Series intelligent DAQ devices and houses up to four NI C Series I/O modules for low-cost signal conditioning and I/O channel expansion. The NI SHC68-68-RMIO cable is designed and shielded specifically for connector 0 of multifunction intelligent DAQ devices and the NI SHC68-68-RDIO cable is designed and shielded specifically for connectors 1 and 2 to reduce crosstalk for improved signal integrity and noise rejection.
