RS232、RS422、RS423和RS485基本上都是物理层协议(OSI第一层)。它们都是串行通信协议,并且是无处不在的设备接口。 RS232、RS485和RS422仅涉及硬件接口,并不涉及软件协议。串行接口广泛用于电子和嵌入式系统,通常用于设备数据的采集或远程控制及信息交换。在我们工业自动化领域也是个非常基础的通信方式。 相对于USB...
Why use RS232 vs RS485 and what is the real difference between RS422 Vs RS485? First, lets define each one. Keep in mind that all three are considered SERIAL,as opposed to IEEE-488 which is PARALLEL. RS232 protocol Definitely the most popular interface, also being one of the first. ...

What is the difference between RS232 and RS485? The RS-485 standard was published in 1983 and is substantially similar to the earlier RS-422 standard. The big difference is support for multiple transmitters and receivers, allowing devices connected on an RS-485 network to "talk amongst themselv...
在RS-232规范中,DTE(数据终端设备)和DCE(数据通信设备)是指串行连接两端的设备类型。一般来说,DTE和DCE分别指计算机设备和调制解调器。因为RS-232规范主要涉及将DTE直接连接到DCE,反之亦然,所以引脚的定义使布线变得简单。 DTE到DCE的连接方式一般采用直通布线方式: ...
