FCC/DOC Radio Frequency Interference Compliance

This equipment generates and uses radio frequency energy and, if not

installed and used in strict accordance with the instructions in this manual,

may cause interference to radio and television reception. This equipment

has been tested and found to comply with the following regulatory agencies:

• The limits for a Class B computing device, in accordance with the

specifications in Part 15 of U.S. Federal Communications Commission

(FCC) Rules. Operation is subject to the following two conditions:

– This device may not cause harmful interference.

– This device must accept any interference received, including

interference that may cause undesired operation.

• The limits for radio noise emissions from digital apparatus set out in

the Radio Interference Regulations of the Canadian Department of

Communications (DOC).

These regulations are designed to provide reasonable protection against

interference from the equipment to radio and television reception in

residential areas.

There is no guarantee that interference will not occur in a particular

installation. However, the chances of interference are much less if the

equipment is used according to this instruction manual.

If the equipment does cause interference to radio or television reception,

which can be determined by turning the equipment on and off, one or more

of the following suggestions may reduce or eliminate the problem.

• Operate the equipment and the receiver on different branches of your

AC electrical system.

• Move the equipment away from the receiver with which it is

interfering.

• Relocate the equipment with respect to the receiver.

• Reorient the receiver's antenna.

• Be sure that the equipment is plugged into a grounded outlet and that

the grounding has not been defeated with a cheater plug.

Notice to user: Changes or modifications not expressly approved by

National Instruments could void the user's authority

to operate the equipment under the FCC Rules.

If necessary, consult National Instruments or an experienced

radio/television technician for additional suggestions. The following

booklet prepared by the FCC may also be helpful: How to Identify and

Resolve Radio-TV Interference Problems. This booklet is available from

the U.S. Government Printing Office, Washington, DC 20402, Stock

Number 004-000-00345-4.

About This Manual

This manual contains instructions for installing and configuring the

National Instruments AT-GPIB interface board and NI-488M multitasking

software for use with the INTERACTIVE UNIX System V Release 3.2

operating system. The hardware and software are intended for use on a PC

AT compatible computer with a 386 or higher processor. This manual is

meant to be used with the National Instruments IEEE 488 Multitasking

UNIX software reference (NI-488M Software Reference Manual, Part

Number 320062-01).

The material in this manual is for users who have extensive knowledge of

This manual also assumes that the user has already received an AT-GPIB

board along with a user manual.

Organization of This Manual

This manual is organized as follows:

• Chapter 1, Introduction, contains a picture of the AT-GPIB board, lists

the contents of your NI-488M kit and optional equipment, and briefly

describes the AT-GPIB board and NI-488M software.

• Chapter 2, Software Installation, lists all the programs and files located

on the distribution disk and contains the steps for installing the NI-488M

software.

• Chapter 3, Hardware Configuration and Installation,contains

step-by-step instructions for unpacking, configuring, and installing your

AT-GPIB board in a PC AT after you have installed your NI-488M

software.

• Chapter 4, Software Verification and Configuration,describes how to

verify the software installation and configure the software. It also

contains information about using the NI-488M software with your

application program and removing the NI-488M software.

• Appendix A, Additional NI-488M Functions, describes three additional

NI-488M functions included in the NI-488M software. These functions

are not described in the NI-488M Software Reference Manual.
