CSE820B converter is a USB to RS232/485/422 interface converter that can realize bidirectional data conversion between USB and serial port without external power supply. This product supports Linux v2.4, Windows98/2000/XP/2003/7 and Mac OS8/9 and other operating systems and provides supporting drivers. It can expand the USB interface to RS232/485/422 serial port, and adopts a unique serial port protection circuit has anti-static, anti-lightning and surge suppression functions. It features built-in intelligent module, automatically identifies the direction of RS485 data flow, automatically forwards with zero delay, and adapts to 0~12Mbps baud rate. Industrial-grade design, with extreme temperature resistance, which can operate stably in -40℃~+85℃ temperature environment. The hardware adopts fanless, low power consumption, and wide temperature design, and can be widely used in indoor and outdoor systems such as attendance, access control, PTZ control, food vending, and parking lots.
