RS-232至RS-485/RS-422智能转换器

A Smart Interface Converter For RS-232-RS-485/RS-422

介绍了如何从RS -2 32信号线上高效率地取得电源 ,如何实现RS -2 32接口与RS - 485 /RS - 42 2接口的智能转换。同时也给出了具体的硬件设计及软件设计方法。

This paper introduces how to high-efficiently generate a supply from RS-232's signal lines and how to intelligently convert a standard RS-232 interface into a RS-485/RS-422 interface,and also presents the method of hardware and software design.
