IEC 60488-2:2004(E)
IEEE 488.2-1992(E)
INTERNATIONAL ELECTROTECHNICAL COMMISSION
____________
STANDARD DIGITAL INTERFACE
FOR PROGRAMMABLE INSTRUMENTATION –
Part 2: Codes, formats, protocols and common commands
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all
national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-
operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to
other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available
Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical
committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work.
International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation.
IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions
determined by agreement between the two organizations.
3)
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC
National Committees.
IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in
that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC
cannot be held responsible for the way in which they are used or for any misinterpretation by any end user.
In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to
the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and
the corresponding national or regional publication shall be clearly indicated in the latter.
IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment
declared to be in conformity with an IEC Publication.
5)
4)
6) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights.
IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC/IEEE 60488-2 has been processed through subcommittee 65C: Digital
communications, of IEC technical committee 65: Industrial-process measurement and control.
This standard cancels and replaces the second edition of IEC 60625-2 (1993).
At times in this standard, specific reference is made to IEEE Std 488.1:1987, which constituted an
earlier version of IEEE Std 488.1:2003, the IEEE edition upon which IEC/IEEE 60488-1:2004 is
based. Where specific dated references were made to the 1987 edition, these references have been
maintained.
The text of this standard is based on the following documents:
IEEE Std
488.2 (1992)
FDIS
65C/320/FDIS
Report on voting
65C/326/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives.
The committee has decided that the contents of this publication will remain unchanged until 2009.
IEC/IEEE 60488 consists of the following publications:
• Higher performance protocol
the standard digital
for programmable
interface
for
instrumentation – Part 1: General (60488-1).
• Standard digital interface for programmable instrumentation – Part 2: Codes, formats,
protocols and common commands (60488-2).
