UT-1208 is a RS-485 Hub special designed for RS485 system under complicated electromagnetic field. With dual core and non-stop running, the transmission rate can be up to 115.2KBPS. To ensure the safety and reliability of the communication, it adopts optoelectronic isolation technology on RS-485 ports; this provides surge & lightning protection with the converter & device; the internal optoelectronic isolator and 1,500W lightning & surge protection circuit provide with 2,500V isolated voltage to prevent from lightning and ESD. At the same time, it prevents from common-grounded interference. This hub adopts external power; it is quite safe and convenient for outdoor application.

Under RS-485 working mode, UT-1208 will detect the data flow direction by distinguishing the circuit automatically; at the same time, it will control the circuit by auto switching, this solves RS485 data receiving and transmitting delay problem. The transmission distance of RS-485 port is up to 1,200m. UT-1208 is widely used in highway toll system, traffic monitoring system and power system.

UT-1208 RS-485 HUB provides with star topology RS-485 connection, each port supports 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-1208 RS-485 HUB in a right way will help you create a unique and reliable RS-485 system.
