Console+ is an all-in-one two port USB KVM switch offering users the possibility of sharing keyboard, mouse and monitor between two or up to four PC. Not like traditioal PS2 KVM devices, Console+ 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 Console+ is 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.
