injury caused by product failure, or by errors on the part of the user or
application designer. Any use or application of National Instruments
products for or involving medical or clinical treatment must be performed by
properly trained and qualified medical personnel, and all traditional medical
safeguards, equipment, and procedures that are appropriate in the particular
situation to prevent serious injury or death should always continue to be

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 two regulatory
agencies:
Federal Communications Commission
This device complies with Part 15 of the Federal Communications
Commission (FCC) Rules for a Class A digital device. Operation is subject
to the following two conditions:
1. This device may not cause harmful interference in commercial
environments.
2. This device must accept any interference received, including
interference that may cause undesired operation.
Canadian Department of Communications
This device complies with the limits for radio noise emissions from digital
apparatus set out in the Radio Interference Regulations of the Canadian
Department of Communications (DOC).
Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les
limites applicables aux appareils numériques de classe A prescrites dans le
règlement sur le brouillage radioélectrique édicté par le ministère des
communications du Canada.
Instructions to Users
These regulations are designed to provide reasonable protection against
harmful interference from the equipment to radio reception in commercial
areas. Operation of this equipment in a residential area is likely to cause
harmful interference, in which case the user will be required to correct the
interference at his own expense.

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 installed and 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.
• Reorient or relocate 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.

Introduction
This chapter contains a description of the GPIB-232CT-A, lists what you
need to get started and optional equipment you can order, contains
instructions for inspecting your GPIB-232CT-A, and gives hardware and
software descriptions.
GPIB-232CT-A Overview
The GPIB-232CT-A is a high-performance serial-to-GPIB interface. It
provides a computer with an RS-232 port, a means of controlling, talking,
and listening on the GPIB. The GPIB-232CT-A is also capable of
interfacing RS-232 instruments and peripherals to the GPIB.
The GPIB-232CT-A has all the software and logic required to implement
the physical and electrical specifications of the IEEE 488 and RS-232
standards. It can interpret and execute high-level commands that you send
to it over the serial port, and perform GPIB-to-RS-232 protocol conversion.
The GPIB-232CT-A also conforms to all versions of the IEEE 488
standard, including IEEE 488.2. The NAT4882 Controller chip implements
all IEEE 488 Talker/Listener/Controller functionality.
Figure 1-1 shows the GPIB-232CT-A.

Inspection
Before you operate the GPIB-232CT-A, inspect the shipping container and
its contents for damage. Keep the packaging material for possible
inspection and/or reshipment.
If the equipment appears to be damaged, do not attempt to operate it.
Contact National Instruments for instructions. If the damage appears to
have been caused in shipment, file a claim with the carrier.
Hardware Description
The GPIB-232CT-A is a high-performance serial-to-GPIB interface product.
It uses the NAT4882 GPIB Controller chip for complete IEEE 488.2
compatibility. You can connect the personal computer serial port to the

Introduction Chapter 1
GPIB-232CT-A for MS-DOS/Windows 1-4 © National Instruments Corp.
RS-232 port for controlling, talking, and listening on the GPIB. The
GPIB-232CT-A is also capable of interfacing RS-232 instruments and
peripherals to the GPIB.
Software Description
NI-488.2 software is part of your GPIB-232CT-A kit. It is a comprehensive
set of programs and drivers for transforming the PC into a GPIB Controller
with complete communications and bus management capability. The
NI-488.2 software also includes the Microsoft C, Microsoft BASIC,
QuickBASIC, and BASICA language interfaces.
National Instruments has developed three other software applications you
can use with the GPIB-232CT-A and PC compatibles: LabVIEW for
Windows, LabWindows®for DOS, and LabWindows/CVI.
LabVIEW for Windows is a software system with interactive graphics,
state-of-the-art user interface concepts, and a powerful graphical
programming language. You must order LabVIEW separately.
LabWindows for DOS enhances Microsoft QuickBASIC and C with an
interactive development program, function panels to generate source code,
and libraries for data acquisition, instrument control, data analysis, and
presentation. You must order LabWindows separately.
LabWindows/CVI extends the power of the LabWindows DOS version with
a more extensive, full-function professional C programming environment for
Windows. You must order LabWindows/CVI separately.
