The product ACX1MR-DHID-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 extension of video and peripheral signals over long distances. The module features a DVI-D video connection as well as two USB HID ports for keyboard and mouse, making it suitable for connecting workstation devices to remote computers. The connection is made via single-mode fibre optic cable with LC connectors, enabling distances up to 10 km. The modules can be used in various enclosure variants, including desktop enclosures with 2, 4, or 6 slots, as well as 48,3 cm ( 19 inch ) rack enclosures with 21 slots. Configuration is achieved by combining transmitter and receiver modules, with the enclosure at the computer equipped with transmitter cards and the one at the workstation fitted with receiver cards.

Applications
This module is intended for point-to-point KVM extensions and for use in KVM matrix switching systems of the DKM FX and DKM FXC series. It is particularly suitable for applications requiring high video quality and stable signal transmission over long distances, such as in data centres, control rooms, or industrial environments. The support for single-mode fibre optic cable makes it suitable for applications where the maximum range of 10 km is to be utilised.

Functions and Equipment in Detail
The module features a DVI-D video connection designed for digital video transmission. The two integrated USB HID ports enable control of keyboard and mouse over the connection. The fibre optic connection via LC connectors provides high bandwidth and is suitable for transmitting video signals over up to 10 km. The modules are part of a modular system that can be adapted to specific requirements by combining different interface modules. Use in modular enclosures allows for flexible scaling of system capacity.

Technology Explained Simply
Transmission occurs via single-mode fibre optic cable, optimised for long distances. The LC connectors ensure a secure and stable connection. Digital signal transmission ensures that image quality is maintained throughout the entire distance without quality loss due to compression. Support for DVI-D enables resolutions up to 2048 x 1152 with single link, while maximum resolution with dual link DVI reaches 2560 x 1600/2x2K. The USB HID ports ensure seamless control of input devices, with signals transmitted transparently.

Compatibility and Accessories
The module is designed for use in modular DKM extender enclosures and can be combined with other base modules as well as upgrade modules for peripheral connections. It is compatible with transmitter modules such as ACX1M1T-DHID-SM and can be used in systems of the DKM FX and DKM FXC series. The modules are designed for use in rack and desktop enclosures, with power supply provided via internal or external power supplies.

Installation and Mounting
Installation is performed by inserting the module into a modular DKM extender enclosure. Connection to the computer is made via a transmitter module connected to the computer, while the receiver module is installed at the workstation. Fibre optic cables are connected using LC connectors. Configuration is done by selecting the appropriate modules and adapting to the desired system architecture. The modules are designed for use in rack and desktop enclosures, with mounting carried out according to the respective enclosure instructions.

Operational Advantages
The modular architecture allows for flexible adaptation to different requirements. The use of single-mode fibre optic cable provides high reach and stable signal transmission. Digital transmission ensures pixel-accurate image quality without quality loss. Support for USB HID ports enables control of keyboard and mouse over the entire distance. Integration into KVM matrix systems extends functionality and enables management of multiple computers from a central workstation.

Protection Rating and Operating Environment
The modules are designed for indoor use and require protected mounting within enclosures. The operating environment must be dry and dust-free to ensure reliable operation. The modules are not designed for outdoor use or in humid environments. Power supply is provided via internal or external power supplies, with voltage settings adjusted to suit the specific application.

Warranty
The product is supplied with a 2-year Double Diamond™ warranty, including comprehensive technical support and spare parts supply. Warranty conditions apply to normal operation and proper installation of the module.

Compatibility with Other Modules
The module is compatible with transmitter modules such as ACX1M1T-DHID-SM and can be used in systems of the DKM FX and DKM FXC series. The modules are designed for use in rack and desktop enclosures, with power supply provided via internal or external power supplies.

Application Scenarios
The module is ideal for applications requiring high video quality and stable signal transmission over long distances. It is particularly suitable for data centres, control rooms, and industrial environments where KVM signal extension over several kilometres is necessary. The modular architecture allows for flexible adaptation to different requirements and integration into existing KVM systems.

Maintenance and Service
The modules require no special maintenance, provided they are properly installed and operated. The warranty includes a 2-year Double Diamond™ guarantee, offering comprehensive technical support and spare parts supply. In case of issues, the manufacturer or an authorised service partner should be contacted.
