The modular KVM extender card ACX1MR-DHID-2C from BlackBox is specifically designed for use in the DKM system and serves as a receiver module for professional KVM matrix solutions. It enables the transmission of DVI-D video and USB-HID signals (keyboard and mouse) over CATx cables and integrates into an existing ACXMOD chassis. The card is designed for use in medium to large installations where flexible, user-defined configuration of KVM systems is required.

Applications
This KVM extender card is suitable for professional applications in data centers, control rooms, media centers, or other environments where multiple workstations must be operated via a central control unit. The use of CATx cables enables a cost-effective and reliable connection over long distances without requiring IP-based network traffic. The card is not IP-capable, ensuring a direct point-to-point or matrix connection, making it ideal for controlled, closed network environments.

Features and Equipment in Detail
The card supports the transmission of DVI-D video and USB-HID signals (keyboard and mouse) over CATx connections. The signals are transmitted via two RJ45 connectors, enabling redundant or parallel connections. The maximum range is 140 meters when using CATx cables with solid conductors and 70 meters with stranded cables. The card features a DVI-I (female) connector for video output, as well as two USB Type-A connectors for connecting keyboard and mouse. A Mini-USB connector is used for communication with the chassis.

Technology Explained Simply
Power supply is provided by the chassis, simplifying installation and reducing the number of required power sources. The operating temperature ranges from +5 °C to +45 °C, and humidity can reach up to 80 %, provided no condensation occurs. The card is designed for use in controlled environments that meet these conditions.

Compatibility and Accessories
The card is compatible with the KVM Matrix Switch – 8-Port High-Speed FIB with Redundant Power. It integrates into the ACXMOD chassis and can be installed in existing DKM systems. The use of CATx cables allows for flexible cabling, with maximum range depending on cable type. The card is not IP-capable, meaning it does not support network protocols such as TCP/IP and is exclusively intended for direct connections via CATx cables.

Mounting and Installation
The card is inserted into an ACXMOD chassis, with mounting based on the connector assignment. Cabling is done using CATx cables with RJ45 connectors on the two interconnect ports. Video output is via the DVI-I (female) connector, while peripheral devices (keyboard, mouse) are connected to the USB Type-A ports. Power is supplied via the chassis, eliminating the need for additional power sources.

Operational Advantages
The card provides a reliable, direct connection over CATx cables with a range of up to 140 meters using solid conductors. Support for DVI-D video and USB-HID signals enables clear separation between video and peripheral signals. Broad operating system support (Windows, macOS, Linux/UNIX, SUN) ensures compatibility across various IT environments. Power supply via the chassis reduces the number of required power sources and simplifies installation.

Certifications
The card complies with CE, FCC, and RoHS certifications, confirming conformity with European and American safety and environmental standards. Manufacturing takes place in Germany.

Operating Systems
The card is compatible with operating systems Windows, macOS, Linux/UNIX, and SUN, enabling flexible use in various IT environments.
