   1port  RS-232 to 4ports RS-485/422 Converter isolation HUB

1.Specification

SW4485 is a RS-485 bus segmentation HUB, specially designed for conforming to RS-485’s large-scale system requirements under the complex electromagnetic environment.Its supporting transmission rates reach up to 115.2Kbps. It adopts transparent transmission in both directions. It can divide a RS485 BUS or RS-232 BUS to 4 RS-485 BUS, or transparently transmit any intersected RS-485 signal to  RS-485 or RS-232 BUS on PC. Each RS-485 port of its lower position controller has reverse fault alarm and protection function,through which,the network reliability of RS485 has been improved, and the maintenance time of network has been shortened efficiently. In order to ensure the safety and reliability of data communication, the RS485 interfaces of SW4485 are supplied with 2KVAC isolation protection, 3 levels of ESD protection and 2 levels of electrostatic radiation protection; they can prevent lighting,common ground and radiated interference, safe and reliable, are suitable for outdoor application.

SW4485 also provide star-RS485 BUS connection. Users can easily improve the RS-485 BUS structure, split network segment. You can design a unique and reliable RS-485 system through making reasonable use of SW4485.

SW4485 adopts EMC protection design, supports wall-mounting and panel-mounting installation, and can be used at the harsh environment from -40°C to 85°C

2.Features

Support two RS-232 and RS-485 PC interfaces , and 4 RS-485 lower position controller ports
