An improved control and monitoring system for managing more than one computer system using a witch with a single connector for keyboard, video and mouse signals for each computer being managed. A notebook style display, keyboard, and pointing device attached to the switch provide a human interface. Each computer is attached to the switch using a cable having a single connector at the attachment point to the switch and separate connectors for keyboard, video, and pointing device signals at the attachment point to each computer, thus allowing a greater density of connections to computers without modifying the computers being controlled and monitored. Even greater densities may be realized by designating one switch as a master and attaching additional switches to the master.
