4. Functionality

The DMK116-17 serves as an integrated rackmount console combining display, keyboard, touchpad, and KVM switching capabilities into a single 1U drawer. It allows administrators to manage multiple servers directly from the rack without the need for separate monitors, keyboards, or mice.

Operation:
- The dual-rail design enables independent sliding of the LCD monitor and keyboard/touchpad tray. The user can pull out the monitor for viewing while keeping the keyboard stowed, or extend both for full console operation.
- The built-in 16-port PS/2 KVM switch connects to up to sixteen servers using PS/2 interface cables. Each connected system can be selected via keyboard hotkeys or on-screen display (OSD) controls.
- The console supports daisy chaining with compatible CKVM108/116 or WKVM108/116 expansion boxes, allowing control of additional servers from a single interface.
- The integrated touchpad provides precise cursor control, eliminating the need for an external mouse.

Applications:
- Data centers and server rooms requiring centralized management of multiple PS/2-based servers.
- Network operations centers (NOCs) and IT infrastructure environments.
- Industrial control systems and test benches where space efficiency and security are critical.
- Secure environments where physical access control is required, supported by the key-lock mechanism.

Compatibility:
- Compatible with PS/2 interface servers and computers.
- VGA video input supports standard analog video output from servers.
- Daisy chain compatible with CKVM108/116 and WKVM108/116 KVM expansion boxes.
