RS485,RS的意义为Recommended Standard的缩写,也就是推荐标准,是一种常用的半双工-异步-串行通信总线。半双工的意思就是两者通信时,同一时刻,只能由其中一方发送,另一方只能接收,不可以同时收发。 RS485作为一种通用的工业应用控制总线,应用非常广泛,因为他具备很多的特点: ...
RS485是美国电子工业协会(Electronic Industries Association,EIA)于1983年发布的串行通信接口标准,经通讯工业协会(TIA)修订后命名为TIA/EIA-485-A。 RS485是一种工业控制环境中常用的通讯协议,其中RS是Recommended Standard的缩写。 RS485 是半双工异步串行通信。
Analog Devices, Inc., and Bourns, Inc., have partnered to extend their offering of system oriented solutions by co-developing the industry’s first EMC compliant RS-485 interface design tool that provi
1、RS-485的电气特性 驱动器能输出±7V的共模电压;接收器的输入电阻RIN≥12kΩ;输入端的电容≤50pF 在节点数为32个,配置了120Ω的终端电阻的情况下,驱动器至少还能输出电压1.5V(终端电阻的大小与所用双绞线的参数有关) 发送端:逻辑"1"以两线间...
RS-232(“RS”缩写为“recommended standard”)于 20 世纪 60 年代推出,作为串行通信的标准化接口。尽管它对于此目的仍然有用,但现在已经存在 RS-485 等替代方案,并且性能显着增强。在本文中,我们将了解 RS-232 和 RS-485 之间最重要的区别。 01
