Description: The ANSI/IEEE Std 488.1-1987, IEEE standard digital interface for programmable instrumentation, deals with systems that use a byte-serial, bit-parallel means to transfer digital data among a group of instruments and system components. The interface system described is optimized as an interdevice interface for system components in relatively close proximity able to communicate over a contiguous party-line bus system. This document contains seven sections as follows: Section 1 contains the scope, the object, basic definitions, and summary description of the interface. Section 2 deals with functional concepts and specifications of the interface system described in this standard. One or more interface functions contained within a device are each able to process messages and change states to maintain an orderly flow of information among a set of interconnected devices. Section 3 deals with the electrical realization of the interface in order to transfer messages among a set of interconnected devices. Section 4 deals with the mechanical realization of the interface in order to implement the electrical aspects of the interface system. Section 5 deals with system considerations that must be given to the design of an individual device in order to make it compatible with other devices of a measurement system. Section 6 deals with system considerations that must be recognized by the user of devices designed in accordance with this standard. Appendixes deal with explanatory matter and examples.
