- Front Panel Buttons: Press the corresponding numbered button (1-8) on the front panel to switch to that input.
- Keyboard Hotkeys: Double-click the Right CTRL key, then press a number key (1-8) to switch to the desired input. A beep sound confirms the switch.
- Mouse Wheel Switching: Press the mouse wheel button twice to cycle through the input computers in sequence.
- IR Remote Control: Use the provided IR remote to select input sources directly.
- RS232 Commands: Send serial commands via the RS232 port for programmatic control.

Auto Detect Mode
The KVM switch can automatically detect and switch to an active input source. When a new PC is turned on, the display will automatically switch to that PC's screen without manual intervention.

Hot Plug Functionality
Devices connected to the KVM switch can be added or removed without needing to power off the KVM switch or the connected PCs. This feature allows for flexible system management.
Image: An input (PC 3) is shown being connected to the KVM switch, and the display automatically recognizes and switches to it, demonstrating hot plug and auto detect mode.
Accidental Input Prevention
The KVM switch includes a feature to lock the screen, audio, and controls with a single button. Pressing the [0/Close] button on the front panel turns off the HDMI display to reduce power consumption. Pressing it again turns the HDMI display back on. When locked, hotkeys and remote controls are also disabled.

6. EDID Emulation
The KVM switch incorporates EDID emulators in each input port. This feature ensures that connected PCs always receive correct display information, preventing display settings from changing or windows from rearranging when switching between input ports. This maintains a consistent desktop layout and prevents screen flicker.
