INTRODUCTIONS 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 dont 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 users guide is only featuring USB Hub. If you like to learn more about USB and its advantages, please visit the following site for more details hitp:-www.usb.org. About this USB Hub The USB HUB is a 4-ports device to bridge the USB interfaced peripherals to your desktop computers or notebook computers. This USB HUB complies with USB Specification Ver. 1.1. It offers you the flexibility of two data rates. The 12Mbps for devices that require increasing bandwidth and 1.5Mbps for low-speed device like game pads and joysticks. Every single one port of the hub allows to daisychain multi devices together. To protect UH400C, Voltage abnormal protection circuit was designed in this device manual reset shall be performed after the protection circuit operated. Features USB 1.1 specification compatibility. Plug-and-Play with USB devices. Auto-switching between Bus-power mode and Self-power mode, indicated by LED. Supports Suspend and Resume Operations. Supports 1 upstream and 4 downstream USB ports. 6 LED indicators for HUB status. 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 500mA 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 tumed 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 Power 1. Plug the B-type connector into the Up Port. Figure 1 2. Plug the A-type connector into the PC site.
