The Rose Vista KM III Keyboard/Mouse Switch enables users to operate up to 8 PC’s/Servers using one common keyboard and mouse. This is particularly useful for command-and-control or control desk environments where work space is at a premium, and the presence of multiple sets of keyboard and mouse can lead to desktop clutter and confusion. The USB keyboard and mouse are connected to the Vista KM III that interfaces directly to the range of PC’s/Servers. The monitors are mounted on the desktop within a comfortable and ergonomic viewing range for the user. The video interface from the PC to the monitor can be DVI, HDMI, Display Port, VGA, or a mixture of any of these video/monitor types as the video connection is transparent to the Vista KM III switch. The Vista KM III can support multiple multi-head computers with no additional software or drivers required. Connect up to 8 single-head, dual-head or quad-head computers using the same simple cabling configuration or even mix dual-head and quad-head computers on the same Vista KM III switch.
