National Instruments Network Device NI PXI-7811R Bedienungsanleitung

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 FPGAVIs.

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 NI-RIO Device Drivers

Complete the following steps to install the NI-RIO device drivers that are

included with the PXI-7811R device. If you are using LabVIEW, complete

the installation instructions in the Installing LabVIEW, the LabVIEW

Real-Time Module for ETS, and the LabVIEW FPGA Module section

before installing the NI-RIO device drivers.

1. Run setup.exe from the NI-RIO CD and follow the setup

instructions.

2. Follow the onscreen instructions until the Feature Tree window

appears.

3. In the Feature Tree window, select the components to install. You must

install NI-VISA, NI-RIO, and NI Measurement & Automation

Explorer (MAX).

4. Follow the onscreen instructions to complete the driver installation.

Installing Hardware

This section describes how to unpack and install the PXI-7811R device.

You can install the PXI-7811R in any available peripheral slot in the PXI

or CompactPCI chassis.

Note You must install the NI-RIO device drivers before installing the PXI-7811R device.

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:

• 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.

Caution 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.
