2. Key Features

- 1U Rackmount Dual-Rail Design:
The DMK108-17 occupies only 1U of rack space, featuring a dual-rail mechanism that allows the LCD panel and keyboard/touchpad tray to slide independently. This enables the display to remain visible while the keyboard is retracted, optimizing space and operational flexibility.

- Integrated 8-Port PS/2 KVM Switch:
Built-in 8-port PS/2 KVM switch allows direct control of up to eight servers or computers using PS/2 interfaces. The system supports daisy-chaining with compatible KVM expansion boxes (e.g., CKVM108/116 or WKVM108/116) for scalable multi-server management.

- High-Quality 17" TFT LCD Display:
The integrated 17-inch A-grade TFT LCD delivers a 1280 × 1024 resolution, 300 cd/m² brightness, and 800:1 contrast ratio, ensuring sharp, clear visuals suitable for continuous operation in data center environments. The display is protected by tempered glass for durability and scratch resistance.

- Full-Size Keyboard with Touchpad:
Equipped with a 104-key notebook-style keyboard including a numeric keypad and integrated touchpad for precise cursor control. The keyboard supports international layouts (default US; optional DE, ES, FR, IT, RU, UK).

- Security and Access Control:
A key-locking mechanism prevents unauthorized access to the drawer, while the self-locking rail system ensures the unit remains securely positioned during operation or storage.

- Ergonomic Viewing and Operation:
The LCD monitor supports up to 130° rotation, providing flexible viewing angles. The dual-rail design enhances user comfort and accessibility in confined rack environments.

- Heavy-Duty Construction:
Built from high-strength steel, the DMK108-17 is engineered for durability and long-term reliability in demanding industrial and IT environments.

- Power and Efficiency:
Integrated 60W auto-switching power supply (100–240 VAC) supports global voltage standards. The unit consumes 3W in standby and 25W during operation, ensuring energy-efficient performance.

- Compliance and Standards:
Meets EIA-310C and IEC-3 rackmount specifications. A UL60950-compliant version is available upon request for enhanced safety certification.

4. Functionality

The DMK108-17 functions as an integrated rackmount console combining display, keyboard, touchpad, and KVM switching capabilities into a single 1U unit. It enables administrators to manage multiple servers directly from the rack without requiring external peripherals.

Operational Workflow:
1. The unit is mounted into a standard 19-inch rack using the included sliding rails.
2. The dual-rail system allows independent movement of the LCD and keyboard tray. The user can pull out the display for monitoring while keeping the keyboard retracted, or extend both for full console operation.
3. The 8-port PS/2 KVM switch connects to up to eight servers via PS/2 and VGA interfaces.
4. Switching between connected systems is achieved through keyboard hotkeys or on-screen display (OSD) controls.
5. The integrated touchpad provides precise cursor control, eliminating the need for an external mouse.
6. The built-in power supply ensures stable operation across global voltage ranges (100–240 VAC).

Use Cases and Applications:
- Data centers and server farms requiring centralized management of multiple servers.
- Industrial automation systems with multiple control computers.
- Network operation centers (NOCs) and IT maintenance facilities.
- Secure environments where physical access control is required.
- Test and development labs managing multiple systems simultaneously.

Compatibility:
- Compatible with standard PS/2 interface servers and VGA video outputs.
- Daisy-chain compatible with CKVM108/116 or WKVM108/116 expansion boxes for extended port capacity.
- Fits standard EIA-310C 19-inch racks.
