USB到多路RS422转换器的电路实现
资料介绍
当USB接口与多个RS422设备进行通信时，由于PC机的USB接口数量有限，这种情况给用户带来极大的不便。为了解决这个问题，采用FTDI公司的F4232H芯片，结合USB总线供电结构，通过简单的外围电路设计出一路USB转4路RS422的转换器。经过测试和实践结果表明，这种方案具有优良的性能和很强的实用价值。
When the computer, which has limited number of USB interfaces, communicating with multiple RS422 devices, there are great inconveniences for the users. In order to solve this problem, this paper uses F4232H chip of FIDT company to design a converter of one-way USB to four-way RS422 by the simple external circuit with the USB bus powered. The testing and practice results show that this scheme has good performance and great practical value.
