User Manual

Overview

Descriptions
A KVM switch is a control device that controls multiple computers from a single console (keyboard, video, and mouse), as many as 512 computers can be controlled from the original console. There is no better way to save space, time, and money than with a KVM switch installation. By using the KVM switch to manage your installation, you will gain the below benefits: (1) eliminate the expense of purchasing separate keyboards, monitors, and mice; (2) save all the space those extra components would take up; (3) save space that a keyboard, monitor and mouse would take with a standard KVM switch; (4) save on energy costs; and (5) eliminate the inconvenience and wasted effort involved in constantly having to move from one computer to another.
It is easy and fast to install the KVM switch, you just need to connect corresponding cables to the right ports of the KVM. Since the KVM directly gets the signal input from the keyboard and mouse, there is no software setup or other complex installation, so no worry about compatibility. Easily access any computer just via pushbuttons on the front panel or invoke the OSD menu. Convenient auto-scan allows you to auto-scan and monitor the selected computer.
