Add Four More USB Ports To Your Desktop
Model UH4100K
The UH4100K is a convenient and cost-effective means of bringing Universal Serial Bus (USB) connectivity to the desktop. The
USB Quad Hub gives you 4 downstream ports for connection to USB-equipped peripherals and 1 upstream port for connection to your
PC or workstation USB port, or to another USB Quad Hub.
The UH4100K complies with USB Specification version 1.0, which provides you the flexibility of supporting both low speed and
high-speed USB device attachment. Features a compact case with EZ-mount bracket for vertical, flat, wall, or under-desk mounting.
The Hub can be bus-powered, conveniently drawing power from a USB host so no power supply is needed. In this mode, the Hub
can draw a maximum of 500mA from the upstream PC or hub. The Hub automatically provides over-current protection from its
upstream power switch in the event that more than 500mA is required by the Hub and downstream devices.
The UH4100K can function in a self-powered mode using an external power supply. In this mode, the Hub provides a maximum of
500mA for each downstream port and each downstream port will have over-current protection in the event a downstream device
attempts to draw more than 500mA.
