Keyboard video mouse (KVM) switch wherein peripherals having source communication protocol are routed via KVM switch and converted to destination communication protocol

A keyboard video mouse (KVM) switch for a plurality of computers to share a plurality of manipulating devices with different connection agreements, the KVM switch comprising:

• a plurality of first interfaces connected to the manipulating devices to receive a plurality of first electrical signals, where each of the electrical signals complies with a source connection agreement of its source manipulating device and each of the first interfaces has a first converting device to convert the first electrical signals into standard packets;
• a switch device, which arranges the routing of the standard packets between the manipulating devices and the computers according to a path selection setting;
• and
• a plurality of second interfaces connected to the computers, where each of the second interfaces has a second converting device to convert the standard packets received from the switch device into a second electrical signal complying with a destination connection agreement of the connected computer, wherein at least one of the source connection agreements is different from at least one of the destination connection agreements.
