Giới thiệu
USB8485I is a USB to RS-485/422 isolated interface converter, which can achieve bilateral switching of data between USB interface and 8 RS-485/422 serial ports. The product supports 1 USB interface and 8 RS-485/422 serial ports. Serial port is equipped with 15kV electrostatic protection and 2kVAC isolation protection, which can effectively protect the device from damage. It adopts desktop mounting to meet the requirements of different application fields.
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 simultaneously communicate with RS-485/422 serial devices via virtual COM port.
Hardware adopts fanless, low power consumption, wide temperature design and has passed rigorous industrial standard tests, which can suit for the industrial scene environment with harsh requirements for EMC. It can be widely used in PLC, Industrial Automatic Control, IC Card Toll Collection System, and Data Acquisition Control System, etc.
