BlackBox ACX1MR-HDSW-2C CATx DKM receiver card, HDMI plus USB HID, with KVM switch for local workstation and HDMI link redundancy content_copy

The product ACX1MR-HDSW-2C from BlackBox is a modular base module for KVM extender systems of the DKM series. It is designed for extending video and peripheral signals over longer distances and enables flexible configuration of KVM systems. The module provides an HDMI video connection as well as two USB HID connections for keyboard and mouse. It is designed for use in modular DKM extender enclosures, available in various sizes with 2, 4, 6, or 21 slots. The modules are used in transmitter and receiver enclosures, with the transmitter module installed at the computer and the receiver module at the console. The connection is made via CATx cables or fiber optics, with CATx connections supporting distances up to 140 meters. For longer distances, fiber optic options are available with multimode (up to 1000 meters) and singlemode (up to 10 kilometers) capabilities.

Applications
This module is suitable for point-to-point KVM extensions as well as for use in KVM matrix switching systems of the DKM FX and DKM FXC series. It is used in environments where central control of multiple computers via remote console is required, for example in data centers, control rooms, or safety-critical installations. The modular design allows adaptation to specific requirements, such as combining different video and USB interfaces within a single system.

Functions and Features in Detail
The module features an HDMI video input supporting resolutions up to 1080p. The two USB HID connections are designed for controlling keyboard and mouse. Additionally, the module includes an integrated KVM switch function, allowing switching between a local and a remote console. This is useful when both local and remote access to a computer is required. The link redundancy function provides a redundant connection, increasing system availability and making it suitable for applications with high reliability requirements.

Technology Explained Simply
Transmission occurs via digital signals, ensuring image quality is maintained without degradation over the entire distance. The CATx connection uses standard network cables, suitable for shorter distances up to 140 meters. For longer distances, fiber optic cables are used, with multimode fiber supporting up to 1000 meters and singlemode fiber up to 10 kilometers. The connection bandwidth is 1 Gbps for standard modules, with high-speed modules available at 2.5 Gbps for demanding graphics applications. Digital signal transmission ensures pixel-accurate resolution and stable signal transmission without interference.

Compatibility and Accessories
The module is intended exclusively for use in modular DKM extender enclosures from BlackBox. It is compatible with other base modules and upgrade modules of the DKM series to realize various interface combinations. The connection is made via CATx cables or fiber optic cables, with fiber optic options supporting both multimode and singlemode cables. The modules can be used in KVM matrix systems of the DKM FX and DKM FXC series to build complex control systems.

Installation and Mounting
Installation involves inserting the module into a modular DKM extender enclosure. The transmitter module is installed at the computer, and the receiver module at the console. The connection between the modules is made via CATx cables or fiber optic cables. The cable type must be selected according to the desired reach and bandwidth. The modules are designed for use in enclosed enclosures and require no additional tools for mounting.

Operational Advantages
The modular design enables flexible adaptation to specific requirements. The integrated KVM switch function allows switching between local and remote console, increasing operational flexibility. Link redundancy ensures higher system availability. Digital signal transmission guarantees high image quality and stable signal transmission over the entire distance. Support for various cable types (CATx, multimode and singlemode fiber optics) provides flexibility in infrastructure planning.
