 Introduction

SW4485I is a RS-485 bus split HUB designed for addressing RS-485 large scale system needs in complex electromagnetic field. 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. Each RS-485 port of this product’s 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. 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. It’s safe and reliable, and appropriate for outdoor engineering application.
 
SW4485I also provides RS-485 bus star connection. User could easily improve RS-485 bus structure and split network segment. Reasonable utilization of SW485I enables you to design a unique and reliable RS-485 system. SW4485I adopts EMC protection and supports Din-Rail mounting and -40℃~75℃ wide operating temperature range, which can meet the requirement of different scenes.
 
 

Features

  • Support 1 RS-232/485 upper computer port, and 4 RS-485 lower computer port
  • Each lower computer port can connect to 32 standard RS-485 devices(nodes)
  • Support cascading of multiple SW4485I, up to 256 RS-485 buses
  • Automatic serial port signal rate detection, support 300bps~115200bps serial port baud rate, zero-delay conversion
  • Serial port provides 15kV electrostatic protection and 2kVAC isolation protection
  • Unique automatic detection and alarm of RS-485 signal reverse connection
