摘要
运用 MAX487芯片设计完成了实用型 RS-485通信接口 ,实现了 RS-2 3 2通信接口与 RS-485通信接口的转换 ,其性能稳定可靠 .同时介绍了使用计算机的 RS-2 3 2串行通信口同 MCS-5 1系列单片机进行远距离串行通信的软件及硬件设计的思想和方法 .
A method of designing a practical RS-485 communication interface with MAX487 is discussed. The converting electric circuit of RS-232 to RS-485 is used in multi computer communication real time minitoring system. The system communication is reliable and has good performance. The design and programming of the RS-232 are given to far\|distant communication with MCS-51 microprocessor.
