National Instruments NI PXI-7811R User Manual
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.

Installing Software
The following instructions describe how to install the NI-RIO device
drivers and LabVIEW.
custom FPGA VIs for the PXI-7811R device
Installing LabVIEW, the LabVIEW Real-Time Module for ETS, and the LabVIEW FPGA Module
Use the following sequence when installing LabVIEW, the LabVIEW
Real-Time Module for ETS, and the LabVIEW FPGA Module. For more
detailed information about software requirements, refer to the LabVIEW
FPGA Release Notes.
If you are using NI-RIO without LabVIEW, skip these steps and complete
the steps in the Installing NI-RIO Device Drivers section.
Note You must install LabVIEW 7.0 or later and the LabVIEW modules you will be using
with the NI 7811R before installing the NI-RIO device drivers. For LabVIEW installation
instructions, refer to the LabVIEW Release Notes.
1. Install LabVIEW for Windows from the LabVIEW CD.
2. Install the LabVIEW Real-Time Module for ETS from the LabVIEW
Real-Time CD.
3. Install LabVIEW FPGA from the LabVIEW FPGA CD.
4. Install the NI-RIO device drivers. Refer to the Installing NI-RIO
Device Drivers section for driver installation instructions.
