4. Functionality

The DMK216-17 functions as an integrated KVM (Keyboard, Video, Mouse) console designed for centralized management of multiple servers or computers within a rack environment. The unit combines a high-resolution LCD monitor, a full keyboard, and a touchpad into a compact 1U drawer that slides out for operation and retracts when not in use.

- Operation:
The user pulls out the drawer to access the keyboard and display. The dual-rail design allows the LCD to remain visible while the keyboard is retracted, facilitating monitoring without occupying additional rack space.

- KVM Switching:
The built-in 16-port combo KVM switch enables direct connection to up to 16 systems via USB or PS/2 interfaces. Switching between connected systems can be performed using on-screen display (OSD) menus, keyboard hotkeys, or front-panel buttons.

- Daisy Chaining:
When connected to CKVM108 or CKVM116 expansion boxes, the DMK216-17 can manage multiple cascaded KVM units, supporting large-scale server infrastructures.

- Applications:
Ideal for data centers, network operation centers (NOCs), industrial control rooms, and enterprise IT environments requiring efficient multi-server management.

- Compatibility:
Compatible with major operating systems including Windows, Linux, UNIX, and macOS, as well as BIOS-level access for system configuration and troubleshooting.
