The video sources of the connected computers enable combinations across all computers (scenarios). The scenarios can be stored within the switch and recalled by pressing a hotkey. A working system consists of one QuadMUX and the required computer connection cable sets.

Product details


Scenario switching

QuadMUX KVM switches provide just as many connections on console and user side as miniMUX4-MC3 + MC4 devices. The most important difference between the units are their switching options.

QuadMUX variants, however, combine the video sources from different computers. These combinations (scenarios) can be retrieved using hotkeys. The correct information mix will be immediately available on three or four monitors. The scenarios are defined in the OSD AdonIS of the QuadMUX.

The computer to which the keyboard is switched by default in that scenario is also defined here. This assignment can be cancelled. You can use hotkeys to switch keyboard or mouse on each of the other computers within the scenario.
