INTRODUCTIONEn
Congratulations and thank you for purchasing the Belkin Hi-Speed USB
2.04-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
2.0hubs. 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.
