该项目定义了一个遵循EIA 574和相关标准的串行、全双工、异步、9针DTE通信端口。几个标准的部分内容将与适用于可编程仪器的特定扩展一起引用。最终的草案将适用于由测量、刺激或互连设备和仪器控制器组成的点对点仪器系统。它也可能适用于仪器系统环境范围之外的某些设备。该文件将涵盖接口的机械、电气和功能要求。

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.
