The product ACX1MR-DHID-C from BlackBox is a modular DKM receiver module for KVM extender systems, specifically designed for extending DVI-D video and USB HID signals (keyboard and mouse). It serves as a receiver module in a modular KVM extender system used in desktop or 48,3 cm ( 19 inch ) enclosures. The modules enable flexible configuration, allowing various video and peripheral interfaces to be combined to meet the requirements of specific applications. The module is suitable for use in point-to-point connections or matrix switching systems of the DKM FX and DKM FXC series.

Applications

The module is used in professional IT environments where it is necessary to transmit computer and peripheral signals over long distances without impairing image quality or the functionality of input devices. Typical application scenarios include data centers, control rooms, medical facilities, or industrial control environments where remote access to computers over large distances is required. Use in modular enclosures enables a scalable and adaptable infrastructure that can be adjusted to growing requirements.

Features and Equipment in Detail

The module features a DVI-D connector for video transmission and two USB HID connectors intended for keyboard and mouse control. Signals are transmitted over CATx cables, with a maximum reach of up to 140 meters. Transmission is digital, ensuring pixel-accurate image quality is maintained. Resolution is limited by video format: for Single Link DVI, maximum resolution is 2048 x 1152; for Dual Link DVI, up to 2560 x 1600/2x2K. The module does not support HDMI or DisplayPort video formats and is specifically designed for DVI-D. The USB HID interfaces enable control of keyboard and mouse, with signals transmitted transparently.

Technology Explained Simply

Digital transmission of the video signal ensures no quality loss, as the signal is not compressed but transmitted pixel-accurately. The use of CATx cables enables a cost-effective and widely available cabling solution already present in many existing networks. The bandwidth of the connection is sufficient to transmit the specified resolutions and USB HID signals. The modular architecture allows the system to be expanded as needed by installing additional modules into the enclosure. Connection between transmitter and receiver modules is via CATx cable, ensuring signals are preserved over the entire distance.

Compatibility and Accessories

The module is exclusively intended for use in modular DKM extender enclosures from BlackBox. It must be combined with a corresponding transmitter module (e.g., ACX1M1T-DHID-C) to enable complete KVM extension. Enclosures are available in various sizes, including desktop versions with two, four, or six slots, as well as 48,3 cm ( 19 inch ) rack enclosures with 21 slots. Power supply can be via internal or external power supplies, supporting AC or DC power (12V, 24V, 48V). The modules are suitable for use in KVM matrix systems of the DKM FX and DKM FXC series.

Installation and Mounting

Installation involves inserting the module into a modular DKM enclosure. Modules are placed into the slots of the enclosure and connected with the appropriate cables. Connection to the computer is made via the transmitter module, which is connected to the computer, while the receiver module is placed at the console. Connection between the two modules is via CATx cables. Power supply is provided by the enclosure, which is equipped with a power supply unit according to the configuration. The modules are designed for use in enclosed enclosures, with detailed mounting instructions included in the respective product manual.

Operational Advantages

The modular architecture offers flexibility and scalability, allowing the system to be expanded as needed. Digital transmission ensures high image quality without quality loss. The use of CATx cables enables a cost-effective and widely available cabling solution. Support for USB HID interfaces allows control of keyboard and mouse over the entire distance. The modules are designed for professional environments and provide a reliable and stable connection. Warranty is 2 years Double Diamond™ (Standard).
