BlackBox ACX1MR-HDMI-SM SM DKM receiver card, HDMI plus USB HID for modular housing content_copy

The product ACX1MR-HDMI-SM from BlackBox is a modular base module for KVM extender systems of the DKM series. It serves as a receiver card in modular enclosures and enables the transmission of HDMI video and USB-HID signals (keyboard and mouse) over long distances. The module is specifically designed for use in point-to-point extensions or in KVM matrix switching systems of the DKM FX and DKM FXC series. It is installed in a modular enclosure with 2, 4, 6, or 21 slots, where at least one base module per enclosure is required. The connection is made via singlemode fiber optic cable, enabling ranges of up to 10 km.

Applications
This module is designed for professional IT infrastructures where centralized control of computers over long distances is required. Typical application scenarios include data centers, security monitoring centers, industrial control systems, or medical facilities, where flexible and scalable KVM extension is needed. The modular design allows adaptation to specific requirements, such as combining different video and peripheral interfaces.

Functions and Equipment in Detail
The module features an HDMI video input and two USB-HID ports intended for controlling a keyboard and mouse. Transmission occurs via an LC fiber optic connector in singlemode format. The maximum range is 10 km, with signal quality maintained throughout the entire distance. Digital transmission ensures pixel-accurate resolution up to 1080p for HDMI signals. Color representation supports 24-bit color depth, ensuring smooth color gradients. The modules are designed for use in switched environments, where the configuration consists of a transmitter enclosure at the computer and a receiver enclosure at the console.

Technology Explained Simply
The technology is based on digital transmission of video signals without quality loss. The use of singlemode fiber optic cable enables high bandwidth and minimal signal attenuation over long distances. Transmission occurs via an LC connector, suitable for use in professional networks. The USB-HID interfaces allow control of keyboard and mouse over the connection, with signals transmitted transparently. The modules are designed for use in modular enclosures, enabling flexible expansion of functionality.

Compatibility and Accessories
The module is intended exclusively for use in modular DKM extender enclosures from BlackBox. It is compatible with KVM matrix switching systems DKM FX and DKM FXC. The connection is made via singlemode fiber optic cable with LC connectors. For expanding peripheral options, modules with transparent high-speed USB 2.0 ports (480 Mbps) are available. The modules can be combined with various video formats, including DVI-D, DVI-I, Dual Link DVI, HDMI, and DisplayPort.

Installation and Mounting
Installation is performed in a modular DKM extender enclosure with 2, 4, 6, or 21 slots. The module is inserted into an available slot and connected to the corresponding interfaces. The connection to the computer is made via a transmitter module connected to the computer. The connection to the console is made via the receiver module, installed in a separate enclosure. Fiber optic cables are connected via LC connectors. Configuration is performed using the associated software tools or via hardware control of the DKM systems.

Operational Advantages
The modular design enables flexible adaptation to different requirements. The use of singlemode fiber optic cable ensures a high range of up to 10 km without signal loss. Digital transmission provides pixel-accurate image quality and stable control of keyboard and mouse. Integration into KVM matrix systems enables centralized control of multiple computers from a single location. The warranty period is 2 years Double Diamond™ (standard).
