Introduction
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 convert 1 RS-485 or RS-232 to
4 RS-485, or transparently transmit any intersected RS-485 signal to
RS-485 or RS-232 on PC. Each RS-485 port of its lower position
controller has reverse fault alarm and protection function, through
which,the network reliability of RS-485 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
RS-485 interfaces of SW4485 are supplied with 2KVAC isolation
Dimension
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.
