#USB HUB WITH ETHERNET IC SERIAL#
The product provides matched driver program software USB interface connected to PC will make up a serial COM port in the computer system. It adopts desktop mounting to meet the requirements of different application fields. Serial port is equipped with 1500W surge protection and 15kV electrostatic protection, which can effectively protect the device from damage. The product supports 1 USB interface and 4 RS-485/422 serial ports. USB4485 is a USB to RS-485/422 interface converter, which can achieve bilateral switching of data between USB interface and 4 RS-485/422 serial ports. SW4485I adopts EMC protection and supports Din-Rail mounting and wide operating temperature range, which can meet the requirement of different scenes. Reasonable utilization of SW485I enables you to design a unique and reliable RS-485 system. User could easily improve RS-485 bus structure and split network segment. SW4485I also provides RS-485 bus star connection.
Its safe and reliable, and appropriate for outdoor engineering application. In order to ensure the safety and reliability of data communication, RS-485 ports of this product are all provided with 2kVAC isolation voltage protection, level-4 electrostatic protection and level-2 radiated immunity protection which could prevent lightning strike, electrostatic and radiated interference.
Each RS-485 port of this products lower computer is equipped with reverse connection fault alarm and protection function, which has improved the reliability of current RS-485 network remarkably and shortened the time of maintaining network effectively.
It supports up to 115.2kbps transmission rate and adopts bidirectional transparent transmission that could split 1 RS-485 bus into 4 RS-485 buses or transparently transmit any RS-485 signal to the RS-485 bus or RS-232 of the upper computer. SW4485I is a RS-485 bus split HUB designed for addressing RS-485 large scale system needs in complex electromagnetic field. 12-48VDC,3-pin 7.62mm pitch terminal blocks
