1-port USB to RS-485 Converter
Introduction
USB485 series are passive pocket USB to RS-485/422 interface converter, which can achieve bilateral switching of data between USB interface and RS-485/422 serial port without external power supply. This series include 2 optional products and provide 1 USB interface, 1 RS-485 or 1 RS-485/422 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-485/422 device via virtual COM port.
USB485 series have compact size and are 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.
