USB232 is a passive pocket USB to RS-232 interface converter, which can achieve bilateral switching of data between USB interface and RS-232 serial port without external power supply. The product supports 1 USB interface and 1 RS-232 serial port. Interface is equipped with 600W surge protection and 15kV electrostatic protection, which can effectively protect the device from damage.

The product provides matched driver program software; USB interface connected to PC will make up a serial COM port in the computer system. PC host can communicate with RS-232 device via virtual COM port.

USB232 has compact size and is easy for installation. Specific LED indicator is convenient for judging signal conversion. It can be widely used in industrial control automation system, bar-code scanner, PLC and PLD, PDA (WinCE system), label printer, POS system, data acquisition control system, security access control system, etc.
