The product ACX1MR-HDO-C from BlackBox is a modular DKM receiver card, specifically designed for extending KVM signals in professional IT environments. It is a base module intended for use in modular DKM extender enclosures to transmit video and USB signals from a computer to a remote console. The card is designed for use with HDMI video outputs and enables transmission of video signals over CATx cables, with a maximum range of up to 140 meters. The card features an HDMI video input and an RJ-45 connector for data transmission. Additionally, two USB HID connectors are integrated for controlling keyboard and mouse. The card is part of a modular system, where transmitter modules are installed at the computer and receiver modules at the console to establish a point-to-point connection or within KVM matrix switching systems of the DKM FX and DKM FXC series.

Applications
This module is suitable for professional applications in data centers, server rooms, control rooms, or other environments where centralized control of computers over long distances is required. It is particularly used in systems where multiple computers are controlled via a KVM system, with signals transmitted over existing network infrastructures (CATx). The use in matrix systems enables flexible control of multiple computers from a single console.

Functions and Equipment in Detail
The module supports HDMI video transmission with a maximum resolution of 1080p. Signals are transmitted pixel-accurately, ensuring clear and distortion-free display. The integrated USB HID connectors enable control of keyboard and mouse, with signals transmitted transparently. The card is designed for use in modular enclosures, allowing flexible configuration of interfaces. Connection is made via an RJ-45 connector, which is connected to CATx cables. The card is designed for use in KVM systems requiring high reliability and stability.

Technology Explained Simply
The card uses KVM extender technology to transmit video and USB signals over long distances. The HDMI signal is transmitted over the CATx cable, with a maximum range of 140 meters. Signals are transmitted digitally, ensuring high signal quality and low latency. USB signals are also transmitted over the CATx cable, with keyboard and mouse control transmitted transparently. The card is designed for use in modular systems, allowing flexible adaptation to specific requirements. The use of CATx cables enables utilization of existing network infrastructures, simplifying installation and maintenance.

Compatibility and Accessories
The module is compatible with modular DKM extender enclosures from BlackBox and can be used in combination with transmitter modules to establish a point-to-point connection or within matrix systems of the DKM FX and DKM FXC series. The card is designed for use with HDMI video outputs and supports signal transmission over CATx cables. Connection is made via an RJ-45 connector, which is connected to CATx cables. The card is TAA-compliant, with the note that compliance applies except for ACX2MT-DLHS-2S.

Installation and Mounting
Installation involves inserting the module into a modular DKM extender enclosure. The card is placed into the enclosure and connected to the appropriate connectors. Connection to the computer is made via a transmitter module installed at the computer. Connection to the console is made via the receiver module inserted into the enclosure. Connection between transmitter and receiver is made via CATx cables connected to the RJ-45 connectors. Installation requires no special tools, as modules are inserted into the enclosure and connections are made via standard connectors.

Advantages in Operation
Using this module enables a flexible and scalable solution for controlling computers over long distances. Utilizing existing network infrastructures (CATx) reduces installation costs and simplifies maintenance. Pixel-accurate transmission of video and USB signals ensures high signal quality and low latency. The modular design allows flexible adaptation to specific requirements, making systems scalable and expandable. The card is designed for use in professional environments, ensuring high reliability and stability. The warranty is 2 years Double Diamond™ (standard).
