The NI PXI-7841R 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 the following:
-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, 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 independent timing and triggering. This offers specialized functionality such as multirate sampling and individual channel triggering, which are outside the capabilities of typical data acquisition hardware. 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 NI LabVIEW FPGA Module Version 8.5.1 or later and NI-RIO Version 2.4 or later driver software.
New Virtex-5 FPGA
The new Virtex-5 field-programmable gate array (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 SHC68-68-RMIO cable is designed and shielded specifically for the multifunction I/O connector (connector 0) of multifunction intelligent DAQ devices. The SHC68-68-RDIO cable is designed and shielded specifically for the digital I/O connectors (connectors 1 and 2) on intelligent DAQ devices to reduce crosstalk for improved signal integrity and noise rejection.
Reduce your setup time and total cost of ownership, and get a system you can use out of the box with National Instruments system assurance programs. System assurance programs include:
Installation and integration test of all individual hardware
Courtesy installation of system driver sets and application development environments
