Getting Started with the NI PXI-7811R This document explains how to set up the National Instruments PXI-7811R device. Introduction The PXI-7811R is an R Series reconfigurable I/O (RIO) device with 160 digital I/O (DIO) lines. Traditional digital I/O devices have a fixed functionality provided by an application-specific integrated circuit (ASIC), but the PXI-7811R has a field-programmable gate array (FPGA) that allows you to define device functionality and timing. You can use the LabVIEW FPGA Module to graphically design the PXI-7811R timing and functionality without having to learn a low-level programming language or a hardware description language (HDL) traditionally used for FPGA design. With the LabVIEW FPGA Module, you create or download a custom virtual instrument (VI) to the FPGA. You can reconfigure the PXI-7811R device with a new VI at any time. You can use the LabVIEW Real-Time Module to communicate and control the PXI-7811R device while performing additional tasks, such as real-time floating-point processing and data logging. Note If you are using LabVIEW but not the LabVIEW FPGA Module, you can create VIs that run in LabVIEW to control existing FPGA VIs, but you cannot create new FPGA VIs. The PXI-7811R device has Flash memory that you can use to store VIs. You can configure VIs to load to the FPGA and to run when the device powers up.

Unpacking The PXI-7811R device ships in an antistatic package to prevent electrostatic discharge from damaging device components. To prevent such damage when handling the device, take the following precautions: Caution • Ground yourself using a grounding strap or by holding a grounded object, such as your computer chassis. • Touch the antistatic package to a metal part of the computer chassis before removing the devices from the package. Never touch the exposed pins of connectors. Remove the devices from the package and inspect the devices for loose components or any other sign of damage. Notify NI if the devices appear damaged in any way. Do not install damaged devices into the computer. Store the PXI-7811R in the antistatic envelope when not in use.
