RS232至RS485转换器的研究

THE STUDY OF A NEW TYPE OF RS232 TO RS485 CONVERTOR

介绍一种RS2 3 2至RS485转换器的原理。给出该转换器的硬件原理图。该转换器能设定波特率 (BaudRate)及自动识别数据流的传输方向 。

A new type of RS232 to RS485 convertor is introduced. The block diagrame of the convertor is given. The convertor can set BaudRate and identify automatically the transmitting direction of data flow .It is suitable for the establishment of the net-type temperature sensor.
