CHAPTER 2
AN INTRODUCTION TO
THE IEEE-488
INTERFACE BUS
STANDARD.
Introduction.
____________
This chapter is divided in to the following main parts.
"The IEEE 488 Standard" takes a look at how the IEEE 488
standard came into being, and gives a simple definition of what
the bus actually is.
"The IEEE Signal Lines" is a brief look at the bus signal lines,
talks about cable length restrictions and data transfer speed
limits.
In "Using The IEEE Bus" the major features of the IEEE 488
system are described.
If you know little about IEEE we suggest that you browse
though the first two parts of this chapter and then carefully read
the rest.

The Beginnings Of A New Standard.

In September 1965 the Hewlett Packard Company realised
that it needed to standardise the way in which all future H.P.

defined.
In March 1972, the IEC committee accepts HPIB as a
starting point for the draft document of its IEC standard which is
published in June 1980 as IEC 625-1.
In April 1975, the Institute of Electrical and Electronics
