KVM Switch
Hotkey Switching
Hardware requirements: A KVM switch that supports hotkey control. The example below uses AIMOS AM-KM202.
Connect the hardware as shown. You can switch the video feed and USB control via hotkeys (virtual keyboard shortcuts) on the web page to achieve one-to-many control.

GPIO Switching
Warning
Tested only on OneCloud and provided for reference; not guaranteed to work in all cases.
Use OneCloud GPIO to control the KVM switch and implement one-to-many control in One-KVM.
Hardware requirements: A KVM switch that supports IR/audio jack control. Connect the audio cable.
Quick method: Strip the audio cable and measure the corresponding voltage. Connect the line with a high level to OneCloud GPIO-420. Then trigger a level change on GPIO-420 from the ATX Power Management menu on the web UI to control the KVM switch, thereby enabling one-to-many control from the One-KVM web UI.
