Description
AU9223 is a highly integrated single chip USB KVM controller offering users the possibility of sharing keyboard, mouse and monitor between two PC. Not like traditional PS2 KVM devices, AU9223 uses USB as its upstream and downstream interface to support its driver-free and plug-n-play features, which allow users to easily install and use the KVM.
Typical application of AU9223 is under an environment, in which only one set of monitor, keyboard and mouse is available. Applying such kind of devices in a computing environment will not only result in a centralized control, but also reduce the power and space consumption.
