User’s Guide

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)
