INTRODUCTION

Congratulations and thank you for purchasing the Belkin Hi-Speed USB

2.0 4-Port TetraHub (the Hub). The Hub provides four downstream USB

ports that offer backward-compatible, Plug-and-Play connectivity with all

USB devices, including USB 1.1 (or low- and full-speed) devices, as well

as with USB 2.0 (or high-speed) devices. This includes such peripherals

as scanners, printers, mass-storage devices, and high-resolution cameras.

The Hub is self-powered, which allows the cascading of devices with

additional hubs, so that up to 127 USB devices may be connected to a

single port.

The Hub features multicolor LEDs that indicate the operating speed of

each connected USB device and the speed of the link to the host

computer. For additional information, refer to the “Technical

Specifications” section.

The TetraHub offers several important advantages over traditional USB

2.0 hubs. Most important is its implementation of the new “Quad TT”

architecture. Simply stated, when connected to a USB 2.0 host

controller, each of the TetraHub’s four downstream ports deliver a full

12Mbps of USB bandwidth for low- and full-speed devices while still

providing total support for high-speed devices. This is especially

important when connecting multiple, bandwidth-intensive, full-speed

devices such as USB webcams, speakers, scanners, and external storage

devices.

INTRODUCTION

In contrast, a traditional four-port USB 2.0 hub provides only 12Mbps of

bandwidth for use by low- and full-speed devices, and this bandwidth is

shared by each of the four ports. The TetraHub delivers up to 48Mbps of

bandwidth, 12Mbps for each port!*

In addition to the “Quad TT” feature, the TetraHub also monitors the

speed of each connected device and provides users with a visual

indication of its connected speed. Refer to the “Determining the Speed

of Connected Devices” section of this User Manual for additional

information.

*In cases in which the TetraHub is connected to a USB 1.1 host

controller, the maximum USB 1.1 bandwidth of 12 Mbps is shared across

all four ports.

INSTALLATION

Important Note: Please do not connect any USB devices to the Hub until

instructed to do so in step 4 of this installation

procedure.

1. Plug the AC adapter into a wall outlet or surge suppressor. Plug the

DC connector into the DC power jack found on the rear of the Hub.

Note: The Hub may be used without the power supply with most USB

devices

2. Plug the flat end (USB-A connector) of the provided USB device cable

into the downstream port of your computer or downstream port of

another hub. Plug the square end (USB-B connector) into the USB-B

connector on the back of the Hub.

Important Note: The Hub must be connected to a USB 2.0-compliant host

in order to function in high-speed mode (480Mbps data

rate). If the Hub is connected to a USB 1.1-compliant

host, it will operate only in low-speed or full-speed mode

(1.5Mbps/12Mbps).

3. Windows will now detect your Hub and install the required driver

support. (The Windows “Install New Hardware Wizard” may prompt

you to provide your Windows Installation CD to complete the driver

installation process).

INSTALLATION

Important Note: High-speed hub drivers are included with most USB 2.0

PCI upgrade cards, and are preinstalled along with the

PCI card drivers. If you purchased an upgrade card prior

to the release of high-speed hub support, please check

with your PCI card vendor for an updated USB 2.0 driver.

The Belkin USB 2.0 driver supports all competitive cards

based on the NEC host controller with the exception of

Adaptec. The most recent Belkin driver is available at

www.belkin.com.
