scope:

This standard defines a serial, full-duplex, asynchronous, 9-pin data terminal equipment (DTE) communications port that follows ANSI/TIA/EIA-574-1990 and related standards. Portions of several standards will be referenced along with specific extensions applying to programmable instruments.

This standard applies point-to-point instrument systems composed of a measurement, stimulus, or interconnect device and an instrumentation controller. It may also apply to certain devices outside the scope of the instrument system environment.

This standard covers mechanical, electrical, and functional requirements of the interface. Intended readers include electrical, mechanical, and software engineers.

Topics covered in IEEE Std 488.2-1992 include the following:

a) Extraction of items in IEEE Std 488.2-1992, which are independent of IEEE Std 488.1-1987.

b) Alternatives for IEEE Std 488.2-1992 functionality that require IEEE Std 488.1-1987.
