当以高数据速率或者长距离进行通信时,差分数据传输可在大多数应用中提供优良的性能。差分信号有助于消除在网络中作为共模电压出现的接地偏移和感应噪声信号的影响。
RS-485规约符合真正多点通信网络要求,并且该标准规定在一条单总线(2线)上支持32个驱动器和32个接收器。有些RS-485收发器修改输入阻抗以便允许将多达8倍以上的节点数连接到相同总线。RS-485最常见的应用是在工业环境下可编程逻辑控制器内部之间的通信。其它常见应用还包括商店的收款机和远程仪器仪表。ADI公司可提供一系列RS-485/RS-422收发器和 iCoupler(R) Isolated RS-485/RS-422收发器以适合多种应用。
