4. Functionality

The DMK108-19 functions as an integrated console for managing multiple PS/2-based servers or computers from a single location. The built-in 8-port KVM switch allows the operator to switch between connected systems using keyboard shortcuts or on-screen display (OSD) controls. Each connected system interfaces via PS/2 connectors for keyboard and mouse signals, and VGA for video output.

The dual-rail design enables independent operation of the LCD and keyboard/touchpad modules. The monitor can remain open for continuous display while the keyboard drawer is retracted, optimizing workspace efficiency. The self-locking rails ensure stability during operation and prevent accidental movement.

Typical use cases include:
- Data Centers: Centralized management of multiple rack-mounted servers.
- Industrial Control Rooms: Monitoring and controlling automation systems.
- Network Operation Centers (NOCs): Real-time system supervision and diagnostics.
- Testing and Development Labs: Multi-system access for software or hardware testing.
- Telecommunications Facilities: Equipment configuration and maintenance.

The DMK108-19 is compatible with standard 19-inch rack enclosures and can be integrated with existing KVM infrastructure via daisy-chaining. It supports connection to CKVM108/116 or WKVM108/116 expansion boxes, allowing scalable system management across larger server arrays.
