Domestic application of ft232 replacing gp232rl usb-rs232 converter chip

With the continuous development of industrial Internet of things ,USB Interfaces are gradually replacing all kinds of vulgar peripheral interfaces of old computers , However, in the current industrial environment , Many important devices are still in use RS232、RS422、RS485 Interface design , So many users use USB turn RS232、RS422、RS485 Converter or conversion line , To realize the computer end and RS232、RS422、RS485 Data transmission between devices .

among ,RS232 It has a long history , It is widely used in many fields . For example, some mechanical control systems , Access control system , Can not be separated from the use RS232 Communication .

USB To RS232 Converter scheme , Use USB turn UART Bridge chip GP232RL, For the device USB Interface to serial communication interface RS232 adapter , It is convenient to link various equipment applications and debugging . It has high compatibility , Meet all kinds of RS232 Serial port device communication . compatible Windows XP/Vista/7/8/10、Linux、MacOS And other series of operating systems .
