RS232
- 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

- 我单位有一无人值守的机房位于一高山山顶上,上山的路是600多级的台阶。因通信需要,有时要开关某些机器设备,操作上虽然简单,但要工作人员花10多分钟爬一趟山,不仅辛苦,而且拖延了时间。为解决此问题,本人利用89C2051单片机,设计了一遥控开关,在山下机房便可对山顶上的设备进行开关机-My unit is an unattended computer room is located in a mountain top of the hill, the road up the mountain is
