4-Port Serial Hub

Interface: compatible with RS-232C and RS-485 standards by EIA/TIA
Electric interface: RS-232C interface for RJ45 socket and RS-485 interface for RJ45 socket
Transmission media: twisted-pair cable or shielded cable
Working mode: asynchronous duplex



As a new RS-485 bus splitting hub specially designed to meet requirements of RS-485 systems under complex electromagnetic environments, UT-2204 supports a transmission rate as high as 115.2Kbps. The external switching power ensures the best safety and stability for outdoors projects.

The direction interpreting circuit under RS-485 working mode is able to perform automatic interpretation of data stream direction for circuit control through automatic shift, therefore the transfer delay for RS-485 is solved. RS-485 interface has a transmission distance of more than 1,200 meters with stable performance.

The RS-485 star bus structure can be easily re-shaped and network range split for improvement of communication reliability. This feature enhances the reliability of the current RS-485 network greatly with effective decrease of time consumption for network maintenance. A proper use of UT-2204 RS-485 hub will surely help you present a nice RS-485 system design of uniquely reliable stability.
