2. Key Features

- 1U Rackmount Dual-Rail Design: The DMK201-19 occupies only 1U of rack space while providing independent sliding rails for the LCD monitor and keyboard/touchpad assembly. This allows the display to remain visible while the keyboard is retracted, optimizing workspace efficiency.
- Integrated 19" TFT LCD Monitor: The built-in 19-inch A-grade TFT LCD panel delivers a native resolution of 1280 × 1024 pixels, 300 cd/m² brightness, and an 800:1 contrast ratio. The display supports a wide 170° (H) / 160° (V) viewing angle for clear visibility from multiple positions.
- Full-Size Keyboard with Touchpad: A 104-key notebook-style keyboard with integrated touchpad provides intuitive control. The keyboard includes a numeric keypad and cursor block for full functionality.
- USB Interface: The console connects to host systems via a standard USB interface for keyboard and mouse input, and a VGA D-Sub 15-pin connector for video.
- Self-Locking Dual Rail Mechanism: The precision-engineered dual-rail system includes a self-locking feature that secures the drawer in both open and closed positions, preventing accidental movement during operation.
- Key Lock Security: A built-in key-locking mechanism restricts access to authorized personnel, enhancing physical security in shared rack environments.
- Tempered Glass Screen Protection: The LCD panel is protected by a tempered glass layer, safeguarding against scratches, impacts, and dust.
- Flexible Viewing Angle: The monitor can be tilted up to 130 degrees, allowing users to adjust the viewing angle for optimal ergonomics.
- Universal Power Supply: Integrated 60W auto-switching power supply supports 100–240 VAC input, ensuring compatibility with global power standards.
- Compliance with EIA-310C and IEC-3 Standards: The unit conforms to standard 19-inch rackmount specifications, ensuring compatibility with most rack enclosures.
- Optional Keyboard Layouts: Available in multiple international layouts including US (default), DE, ES, FR, IT, RU, and UK.
- UL60950 Version Available: A UL60950-compliant version can be supplied upon request for installations requiring certified safety compliance.

4. Functionality

The DMK201-19 functions as an integrated rackmount console, combining display, keyboard, and pointing device into a single compact drawer. It connects directly to a server or KVM switch via VGA and USB interfaces, allowing administrators to manage systems locally without the need for external peripherals.

Operation:
- The dual-rail design allows the LCD monitor and keyboard/touchpad to slide independently. Users can pull out the monitor for viewing while keeping the keyboard retracted, or extend both for full console operation.
- The LCD panel displays the video output from the connected system through the VGA interface.
- The keyboard and touchpad provide direct input via USB, functioning as standard HID (Human Interface Device) peripherals.
- The built-in power supply automatically adapts to AC input voltages between 100 and 240 V, eliminating the need for external adapters.
- The key-lock mechanism secures the drawer in the closed position when not in use, preventing unauthorized access.

Use Cases and Applications:
- Data Centers: Ideal for rack-based server management, allowing administrators to access servers directly within the rack.
- Industrial Control Systems: Suitable for machine control cabinets and automation systems requiring integrated display and input.
- Network Operations Centers (NOCs): Provides a compact local console for monitoring and troubleshooting network equipment.
- Telecommunications Racks: Enables on-site configuration and diagnostics of telecom hardware.
- Testing and Development Labs: Offers a convenient interface for engineers working with rack-mounted test systems.

Compatibility:
The DMK201-19 is compatible with any system supporting VGA video output and USB keyboard/mouse input, including Windows, Linux, UNIX, and embedded operating systems. It can also be connected to KVM switches for multi-server management.
