This product is a modular DKM Extender base module by BlackBox, specifically designed for use in KVM systems. It serves as a transmitter card with HDMI and USB HID interfaces and is designed for integration into modular enclosures with up to 21 slots. The modular design enables flexible adaptation to different requirements in the field of signal extension for video, USB, and peripheral signals.

Applications

The base module is used in KVM matrix switching systems (DKM FX/FXC) as well as in point-to-point KVM extensions. It is particularly suitable for applications where graphically demanding content must be transmitted losslessly over long distances, such as in data centers, control rooms, or for controlling servers in remote rooms. Support for HD and 4K video applications also makes it suitable for professional image processing and monitoring systems.

Functions and Features in Detail

The module supports multiple video formats, including HDMI, DVI-D, DVI-I, and DisplayPort. The HDMI interface allows a maximum resolution of 1080p, while DisplayPort supports up to 4K resolution. For Dual Link DVI, the maximum resolution is 2560 x 1600/2x2K. Transmission occurs via CATx cables or fiber optic (multimode/singlemode), with range varying by medium: up to 140 meters with CATx, 1000 meters with multimode fiber, and up to 10 kilometers with singlemode fiber. Bandwidth reaches up to 2.5 Gbps, ensuring high image quality and low latency.

For keyboard and mouse control, two USB HID ports are integrated. Additionally, the module offers a peripheral option with four USB 2.0 Highspeed ports (480 Mbps), which can be used to connect additional devices such as printers or storage devices.

Technology Explained Simply

The modular architecture enables scalable system expansion. The base module can be installed in various enclosure sizes (2, 4, 6, or 21 slots), allowing multiple modules to be combined. Connection via CATx or fiber optic enables flexible adaptation to existing infrastructure. The fiber optic option is particularly suitable for longer distances, as it exhibits lower signal loss. Support for redundant links and integrated 2-port switches (as upgrade modules) increases system reliability and expands functionality.

Compatibility and Accessories

The module is designed for use in KVM matrix switching systems (DKM FX/FXC). It can be combined with various upgrade modules to add features such as redundant connections or integrated network switches.

Mounting and Installation

Installation is performed by inserting the module into a compatible modular enclosure. Connection options for video, USB, and peripherals are clearly marked. The included installation manual supports correct setup. Power supply is provided via an optional redundant power supply unit, which can be mounted internally or externally and supports AC/DC voltages (12V, 24V, 48VDC).

Operational Advantages

The modular design and support for various video formats and transmission media offer high flexibility. High bandwidth and support for 4K and HD video ensure clear, pixel-accurate image transmission. The ability to use multiple video channels in parallel makes the system suitable for complex working environments. The warranty is 2 years under the Double Diamond™ standard.
