The module ACX1MT-HDM2-2C from BlackBox is a base module for modular DKM KVM extenders, specifically designed for extending HDMI video and USB signals over CATx connections. It serves as a transmitter card installed on a computer to transmit signals via a network cable to a receiver module at the console. The module enables HDMI video transmission with a maximum resolution of 1080p and provides two USB HID ports for keyboard and mouse. The connection is made via an RJ-45 port designed for CATx cables, allowing distances up to 140 meters. Digital signal transmission ensures pixel-accurate reproduction without quality loss, supporting 24-bit color depth.

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 where a computer is physically located away from the control console, for example in server rooms, control rooms, or industrial environments. The modular design allows flexible adaptation to different requirements, such as combining with other modules for various video or USB interfaces.

Functions and Features in Detail
The module features an HDMI video input and two USB HID ports designed for keyboard and mouse control. Transmission occurs via an RJ-45 port designed for CATx cables (e.g., Cat 5e or Cat 6). The maximum range is 140 meters, with signal quality maintained throughout the entire distance. The use of CATx cables simplifies installation and is cost-efficient, as standard network cables can be used. The modules are intended for use in modular DKM extender enclosures, available in desktop or 48,3 cm ( 19 inch ) versions with various slot capacities.

Technology Explained Simply
The transmission technology is based on digital signal transmission over CATx cables, avoiding any analog signal loss. HDMI signals are transmitted pixel-accurately, with a maximum resolution of 1080p. USB signals are transmitted via the two HID ports (keyboard and mouse), with signals routed directly to the console. The use of CATx cables enables simple installation, as no special fiber optic cables are required. The connection bandwidth is sufficient to meet requirements for standard and high-performance PC applications.

Compatibility and Accessories
The module is exclusively intended for use in modular DKM extender enclosures from BlackBox. It must be used together with a receiver module at the other end of the connection, with configuration consisting of transmitter and receiver cards. The modules can be combined with other interface modules (e.g., DVI, DisplayPort, USB 2.0) to create custom configurations. Use in KVM matrix systems of the DKM FX and DKM FXC series is also possible.

Installation and Mounting
The module is installed into a modular DKM extender enclosure, available either as a desktop device or mounted in a 48,3 cm ( 19 inch ) rack. Installation involves inserting the module into an available slot in the enclosure. Connection to the computer is made via HDMI and USB ports, while the connection to the console is established via the RJ-45 cable. Configuration is done by selecting the appropriate transmitter and receiver modules, with modules installed in one enclosure for the computer and a separate enclosure for the console.

Operational Advantages
The modular design allows flexible adaptation to different requirements, with modules easily replaceable or expandable. The use of standard CATx cables reduces installation costs and simplifies cabling. Digital signal transmission ensures high image quality without quality loss. Support for 24-bit color depth ensures natural color reproduction. The maximum range of 140 meters offers sufficient flexibility for many applications. The warranty period is 2 years Double Diamond™ (standard).
