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℃.

RS-485 Port fault alarm and protection
RS-485 port fault alarm and protection is the
solution to connect multiple RS-485 devices, an effective
way to enhance its reliability. SW4485 HUB has 4 lower
position controller ports, and each port has reverse
connect protection function, and can work in shutdown
mode. Any RS-485 port reverse connection will only
affect its RS-485 BUS system, will not affect the normal
work of other interface connected with RS-485 system.
Users can quickly determine fault port and other
connected devices according to the fault alarm light.
Note: The connection of lower position controller
ports of the same SW4485 HUB is wrong
connection.
【LED Indicator】

The LED indicator’s monitoring working state of
SW4485 HUB can fully simplify resolution of fault.
Detailed states of each indicator are shown in the

【Installation】
To confirm the device’s working environment
before installation: the supply voltage, the installation
space, the installation method, etc. Please confirm the
following installation requirements carefully:
◎Check installation needed cables and
connectors
◎Based on reasonable configuration
requirements, check the cable is in
place(less than 100m)
◎Product does not provide installation
components, users need to prepare them
according to the selected type: screws,
nuts and tools to ensure reliable
installation.
◎Power: 5VDC
◎Environment:
Working Temperature: -40~85℃
Humidity: 5%~95%
◎Installation Type: Wall-mount and
Panel-mount
Cable Laying
Cable laying should meet the following conditions:
◎Check all cable specifications, models and
quantity meet the demand or not before cable
laying.
◎Check the cable is damaged or not , whether
has factory leaving record and quality
assurance or other quality certificate.
◎Required laying cables’ specifications,
quantity, direction, laying position are adhere
to construction requirements, laying length
should be based on the actual location.
◎The laying cable do not have broken line or
connector in the middle
◎Cables should be straight int the aisle neatly
inside, turning uniform, smooth and flat.
◎Cable in the channel should be straight, not
beyond the channel in order to avoid shelter
other inlet and outlet holes, cable out of the
groove part or cable bend part should be
bundled and fixed.
◎User cables and power cord lay separately.
Cable, power cord, ground lay in the same
channel can not be folded or blended. If the
cable is too long, it must be placed in the
middle of the cable frame regularly rather
than pressed on other cables.
◎The end of the cable should be labeled
appropriately, and the identify content
must be clear and concise to have convenient
maintenance.
