### 4. Functionality

Operation Overview:
The DMK585 integrates a monitor, keyboard, touchpad, and KVM switch into a single 1U rackmount drawer. The dual-rail design allows the LCD and keyboard/touchpad to slide independently, enabling the display to remain visible while the keyboard is retracted. The built-in KVM switch enables the operator to control up to eight servers directly, with expansion capability through daisy-chaining additional units.

Use Cases:
- Data centers and server farms
- Network operation centers (NOCs)
- Industrial control systems
- IT maintenance and diagnostics stations
- Secure server management environments

Compatibility:
Supports a wide range of operating systems including DOS, Windows (3.x through XP), Windows NT, NetWare, SCO Unix, HP Unix, and Linux. Compatible with standard PS/2 keyboard, PS/2 mouse, and VGA interfaces.

Control Methods:
- Hotkeys: Quick switching between ports using keyboard commands (e.g., double “Scroll Lock” activation).
- On-Screen Display (OSD): Graphical interface for port selection, naming, password management, and scan configuration.
- Push Buttons: Front-panel buttons for manual port selection.

Security:
Password protection (8-character) prevents unauthorized console access. Console ON/OFF control restricts usage until authentication is completed.

Auto Scan Mode:
Automatically cycles through connected PCs for monitoring, with adjustable scan intervals (5–99 seconds).

Hot Plug Functionality:
Allows connection or disconnection of PCs without powering down the KVM or other systems (except daisy-chain ports). Note: Some operating systems (e.g., SCO Unix) may not support hot plug.
