Introduction
Welcome to the Universal Serial Bus (USB)
HUB, an easy plug and play external simple
device that allowed your computer to connect to
USB Interfaced monitors, printers, digital
speakers, modems, digital cameras, joysticks or
multimedia equipment.
Technology Overview
Universal Serial Bus ( USB ) technology is an
instant and no-hassle solution for computer
users who have ever dreamed about to connect
their computers to many computer peripherals.
Up to 127 USB devices can be connected all
together in this way. All you need is just to plug
them in and turn them on. USB will configure
everything for you automatically. From now on,
you don’t need to worry about opening up your
computer case, add-on cards, DIP switch setting
or IRQs.
Other key features about USB are “hot-swap”,
Automatic Power sensing. This user’s guide is
only featuring USB Hub. If you like to learn

Hardware Installation
Installation of the USB Hub is easy. Two
different methods to install the hardware – Bus
powered and Self-powered. You can choose
either one of them to install your USB Hub.
Power Mode Selection
Please read this note carefully before you select
the power mode.
For Bus Powered mode, UH400 provides 500
mA in total for all four downstream ports . Each
downstream port shares with 100mA current.
Any USB device consumes more than 100mA ,
the device may not able to be turned on. Then
you should select Self-powered mode to power
up the device.
For Self-Powered mode, each downstream port
is 500mA (max) supplied. This power is
sufficient enough to support most of the USB
devices.
Using Bus Powered
1. Plug the B-type connector into the
“Up Port” (See Fig I)
2. Plug the A-type connector into the PC
site (See Fig II)
3. Connect USB devices to the Hub:
Down 1 - Down 4 (See Fig III)
Using Power Adapter
1. Plug the DC plug into DC jack
located on the back panel of the Hub
2. Plug the AC adapter into an electronic
outlet
3. Plug the B-type connector into the
“Up Port” (See Fig I)
4. Plug the A-type connector into the PC
site (See Fig II)
5. Connect USB devices to the Hub :
Down 1 - Down 4 (See Fig III)
