4. Functionality

The DMK116-19 serves as an integrated console solution for managing multiple servers or network devices within a rack environment. The unit combines display, input, and switching functions into a single compact assembly:

- Operation:
The user slides out the drawer to access the keyboard and monitor. The dual-rail design allows the LCD to remain open while the keyboard is retracted, providing flexible viewing and space management.

- KVM Switching:
The built-in 16-port PS/2 KVM switch enables control of up to 16 connected systems. Switching between systems can be performed via keyboard hotkeys or on-screen display (OSD) menus, depending on configuration.

- Daisy-Chaining:
For larger installations, multiple DMK116 units or compatible CKVM108/116 boxes can be daisy-chained, expanding the total number of controllable systems while maintaining a single user interface.

- Applications:
Ideal for data centers, server farms, network operation centers (NOCs), and industrial control environments where space efficiency, security, and centralized management are critical.

- Compatibility:
Supports PS/2 interface connections for both keyboard and mouse. Video input is via standard VGA connector, ensuring compatibility with a wide range of legacy and modern server hardware.
