Functions of each button on the KVM switcher

KVM switch buttons allow users to select input ports, lock the console, activate hotkeys, and manage display and peripheral settings for multiple computers.

Front Panel Buttons

Front panel buttons on a KVM switch are typically used to toggle between connected computers. Pressing a button corresponding to a specific port will redirect the keyboard, video, and mouse signals to that computer. Some KVMs also bind hub, audio, and microphone ports to the same button, so switching a port can simultaneously switch USB peripherals and audio channels. A confirmation beep often indicates a successful selection .

Keyboard Hotkeys

Many KVM switches support keyboard hotkeys for switching inputs without using the front panel. Common hotkey sequences include pressing Scroll Lock twice followed by a number key to select a specific computer port. Additional hotkeys can enable features such as:

• Mouse wheel switching mode: Scroll Lock → Scroll Lock → F6 to toggle mouse wheel input switching.
• Auto-scan mode: Scroll Lock → Scroll Lock → Space to cycle through connected computers automatically .

On-Screen Display (OSD) Buttons

Some KVM switches include an OSD menu accessible via front panel buttons or hotkeys. The OSD allows users to:

• Assign labels to each input source (e.g., PC, Mac, Laptop, Game) for easier identification.
• Configure one-touch switching for each input.
• Set lock functions to secure the KVM when leaving the console, requiring a PIN to unlock .

Lock and Security Buttons

Certain KVMs provide a lock function to prevent unauthorized access. Activating the lock typically involves a hotkey combination (e.g., Scroll Lock + Scroll Lock + L) and requires entering a PIN to unlock. This ensures that the KVM cannot be switched while unattended .

IR Remote Control Buttons

Some models include an IR remote for switching inputs. Each button on the remote corresponds to a specific input port, allowing users to switch computers without touching the KVM or keyboard .

Summary

• Front panel buttons: Directly select input ports and may control hub/audio ports.
• Keyboard hotkeys: Enable quick switching, auto-scan, and mouse wheel mode.
• OSD buttons: Manage labels, one-touch switching, and display settings.
• Lock buttons: Secure the KVM with a PIN.
• IR remote buttons: Provide remote input selection. These buttons collectively allow seamless control of multiple computers from a single console, improving efficiency, reducing clutter, and enhancing security .
