Product Description

Overview

 RS-485 HUB provides with star topology RS-485 connection, each port support short circuit, open-circuit protection. Users can easily change RS-485 BUS structure, and cut the network segment to improve the communication reliability. When lightning or the equipment breaks down, the network segment with problem will be isolated, to make sure the other network segment works regularly. This performance enhances the reliability of RS-485 network, and shortens the network maintenance time. Using UT-1208H RS-485 HUB in a right way will help you create a unique and reliable RS-485 system.
