Overview of 3onedata’s USB to 1 Port RS-232 RS-485 RS-422 Converter USB485I

USB485I is a USB to RS-232/485/422 interface converter, which can achieve bidirectional data conversion between USB interface and RS-232/485/422 serial ports. The product supports 1 USB interface and 1 RS-232/485/422 serial port. RS-485/422 supports serial port self-adaption technology, which can identify RS-485/RS-422 serial port with no need of switch setting. Serial port is equipped with 8kV electrostatic protection and 2kV isolation protection, which can effectively protect the device from damage. It adopts wall 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 automatically. PC host can communicate with RS-232/485/422 serial devices via virtual COM port.
Hardware adopts fanless, low power consumption, wide temperature and voltage 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.
