Claims8
A KVM switcher (multi-computer switcher) with integrated parallel transmission, serial peripheral interface (SPI), and universal serial bus (USB), including:
- a SPI master control unit, with a SPI master device interface and a parallel transmission interface;
- at least one USB host interface control unit, with an USB interface for connecting the peripheral device of the USB interface, and a parallel transmission interface and a SPI slave device interface for connecting the SPI master device interface of the SPI master control unit, in which the parallel transmission interface of the USB host interface control unit selectively and electrically connects the parallel transmission interface of the SPI master control unit;
- and
- at least one USB device control unit, with an USB interface for connecting at least one USB interface of a computer or at least one USB hub, and a SPI slave device interface for electrically connecting the SPI master device interface of the SPI master control unit;
- characterized in that signals are transmitted through the parallel transmission interface between the SPI master control unit and the at least one USB host interface control unit.
