Description: 串行通信接口标准经过使用和发展，目前已经有几种。但都是在RS-232标准的基础上
经过改进而形成的。所以，以RS-232C为主来讨论。RS-323C 标准是美国EIA(电子工业联合
会）与BELL等公司一起开发的1969 年公布的通信协议。它适合于数据传输速率在0～
20000b/s 范围内的通信。这个标准对串行通信接口的有关问题，如信号线功能、电器特性
都作了明确规定。由于通行设备厂商都生产与RS-232C制式兼容的通信设备，因此，它作为
一种标准，目前已在微机通信接口中广泛采用。-Serial communication interface standard through the use and development, now has several. But they are in the RS-232 standard based on an improved formed. Therefore, to RS-232C-oriented discussion. RS-323C standard is the United States EIA (Electronic Industry Association) and BELL and other companies in 1969 announced the development of communication protocols. It is suitable for data transfer rate in the 0 ~ 20000b/s within the scope of communication. The standard serial communication interface of the relevant issues, such as the signal line features, electrical characteristics have been clearly defined. Since the passage of equipment manufacturers have production and standard RS-232C compatible communications equipment, so that it as a standard has been in the computer communication interface is widely used.

Description: 作为上世纪80年代早期批准的一个平衡传输标准，RS-485似乎已成为工业界永不过时的接口标准。关于它的文献有很多，但对于很少接触接口设计的系统工程师而言，如此海量的文献就有些让人吃不消了。
本文旨在讨论RS-485标准的主要内容，为初接触它的设计师提供入门指南。研究文末参考的一些附加应用笔记可进一步帮助设计师在最短的时间内完成一套可靠的数传设计。
-As the last century, the early 80 s approval of a balanced transmission standard, RS-485 seems to have become the industry standard interface never outdated. Literature about it a lot, but seldom come into contact with the system interface design engineers, such a mass of literature on some people too much of. This paper aims to discuss the RS-485 standard of the main elements for the early exposure to its designers Getting Started Guide. Study the text at the end of the reference number of add-on application notes, could further help to designers in the shortest time possible to complete a set of reliable data-transmission design.

Description: RS-232、RS-422与RS-485都是串行数据接口标准，最初都是由电子工业协会（EIA）制
订并发布的，RS-232在1962年发布，命名为EIA-232-E，作为工业标准，以保证不同厂家产品
之间的兼容。RS-422由RS-232发展而来，它是为弥补RS-232之不足而提出的。为改进RS-232
通信距离短、速率低的缺点，RS-422定义了一种平衡通信接口，将传输速率提高到10Mb/s，
传输距离延长到4000英尺（速率低于100kb/s时），并允许在一条平衡总线上连接最多10个接
收器-RS-232, RS-422 and RS-485 serial data interface standards are the first by the Electronics Industry Association (EIA) and published in, RS-232 issued in 1962, named for the EIA-232-E, as the industry standard to ensure that different manufacturers of compatible products. RS-422 by the development of RS-232, which is designed to remedy the lack of RS-232 made. RS-232 to improve the short-distance communications, the shortcomings of low-rate, RS-422 defines a balance between communication interface transfer rate up to 10Mb/s, transmission distance was extended to 4000 feet (at rates of less than 100kb/s), the and allow the balance on a bus to connect up to 10 receivers
