• 基本释义

1.It can also distinguish automatically 10 bits from 11 bits communication mode and the communication baud rate from 1 200 to 115.2 k. It can realize duplex or semiduplex communication between one RS-232 SCI to four RS-422/RS-485 SCIs without necessarily changing the existing software of PC.
在单片机控制下,能够自动识别通讯方式(10位、11位方式)和通讯波特率(1200～115.2k),可以在不改变微机已有控件的情况下,实现一个RS-232串行口与4路RS-422/RS-485串行口之间的全或半双工通信.收藏指正
