6.4.1 IEEE-488 Interface Configuration
The IEEE-488 Interface is a parallel BUS for Communication in the Program-
mable Instruments. Multiple instruments can be connected on the same BUS and
can be hooked up to a single HOST controller or computer. In order that instruments
from different manufacturers can be built into the same system, it was necessary
that all interfaces be compatible. To ensure this, the interfaces were made to con-
form to a standard specification as detailed in the publication ANSI/IEEE Std. 488-
1978 called ‘IEEE Standard Digital Interface for Programmable Instrumentation’ (And
also to ANSI/IEEE std.488.1-1987) and this came to be known as IEEE-488 or GPIB
Interface.
The following list highlights the salient characteristics of the IEEE-488 Inter-
face:
DATA RATE 1 MB/Sec. MAX.
NO. OF DEVICES 31 MAX.
BUS LENGTH 20 Meters. MAX.
DATA LENGTH 8 BITS / 1 BYTE
