Abstract:
1. A switching device comprising: an input port configured to receive output signals from a keyboard and a mouse; a first output port coupled through a hardwired cable to a first keyboard port and a first mouse port on a first computer workstation, the first computer workstation comprising: a second output port coupled through a hardwired cable to a second keyboard port and a second mouse port on a second computer workstation, the second computer workstation comprising; a third output port coupled through a hardwired cable to a third keyboard port and a third mouse port on a third computer workstation, the third computer workstation comprising: a first output display port coupled to a first display; a second output display port coupled to a second display; a controller switch that automatically routes the output signals at the input port to the first output port when the controller switch is in a first state, the controller switch automatically routing the output signals at the input port to the second output port when the controller switch is in a second state, the controller switch automatically routing the output signals at the input port to the third output port when the controller switch is in a third state, wherein the controller switch changes between the first, second and third states when the first, second and third switch command signals are received by the controller switch via at least one of the first, second and third output ports, the controller switch routing display signals from two of the first, second and third computer workstations to the first and second output display ports in a predetermined sequence, the controller switch routing display signals from the first computer workstation to the first output display port and routing display signals from the second computer workstation to the second output display port, and in response to receiving the second switch command signal, the controller switch routes display signals from the second computer workstation to the first output display port and routes display signals from the third computer workstation to the second output display port, and in response to the third switch command signal, the controller switch routes display signals from the third computer workstation to the first output display port and routes display signals from the first computer workstation to the second output display port.
