IEEE 1174:2000 (R2009)

New IEEE Standard - Inactive-Reserved.
A serial, full-duplex, asynchronous, 9-pin data terminal equipment (DTE) communications port for programmable instrumentation that follows ANSI/TIA/EIA-574-1990 and related standards is defined in this standard.

This project defines a serial, full-duplex, asynchronous, 9-pin DTE communications port that follows EIA 574 and related standards. Portions of several standards will be referenced along with specific extensions applying to programmable instruments. The resulting draft will apply to 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. The document will cover mechanical, electrical and functional requirements of the interface.
Adapt IEEE Std 488.2 syntax, commands and protocols for use with programmable instrumentation using point-to-point serial interfacing instead of or in addition to IEEE Std 488.1. Retain a high level of commonality of programmable interfacing with devices using IEEE Std 488.2 and IEEE Std. 488.1 as the physical layer. Utilize applicable existing communication protocols where possible.
