From now on, you don‘t need to worry about opening up your computer case, add-on cards, DIP switch setting or lRQs. 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 more about USB and its advantages, please visit the following site for more details ‘ httpfwwwmbprg. 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 LSMbps 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.
