SW4485 HUB
Instructions
【
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 divide a RS-485
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 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 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
℃
to 85
℃
.
