摘要
设计了一种无源的RS - 2 32 /RS - 4 85智能转换器 ,详细说明了从RS - 2 32串口上窃取电源以及完全由硬件控制MAX4 85收发使能的硬件实现电路。该转换器体积小、电路结构简单、工作可靠等特点 ,能满足大部分工业现场的使用要求。
In this paper a smart interface converter was designed for RS-232/RS485. And the detailed method of hardware circuitry was presented for stealing power from the serial interface of RS-232 and hardware control for enabling of MAX485.This kind of converter has many charactreistic.such as small volume,simple circuitry structure,high reliability.So it can meet the need of most practical application.
