Overview
RS-485 HUB supports star RS-485 BUS connection. Each port supports short-circuit, open-circuit protection, 2,500V optoelectronic isolation. User can easily change the structure of RS-485 BUS, divide the network segment, and improve the communication reliability. When the device break down, the network segment with problem will be isolated, so as to ensure other network segment working smooth; this performance greatly improve the reliability of RS-485, and shorten the maintenance time of the network.
