Introduction
UIH-420 is a Universal Serial Bus (USB) hub,
which is an USB cable concentrator and a
bridge between PC’s PCI interface and USB
devices. With UIH-420, there is no need to
concern about IRQ conflicts or system resource allocations any more.
UIH-420 supports USB 2.0 high speed of
480Mbps and USB 1.1 full speed (12Mbps)
and low speed (1.5Mbps). Through the four
type-A downstream ports, up to 127 USB devices can be connected with just plug and play.
UIH-420 is the ideal way to make use of USB
2.0 technology.
