Key Product Advantages

The ACX1MT-U23-C transmitter provides several distinct advantages for organizations needing to extend computer access beyond typical cable limitations. Its modular architecture allows integration into existing Black Box DKM FX systems, while standard CATx cabling reduces deployment complexity and cost compared to specialty media solutions.

Extended Operational Range

Delivers reliable KVM and USB extension up to 400 feet using common network cabling, eliminating the need for expensive fiber runs in many mid-range distance scenarios.

  • Utilizes CAT5e/6/6a cabling
  • Maintains USB 2.0 speed at full distance
  • No signal degradation within specified range

Broad Platform Compatibility

Supports virtually all major computing environments including Windows PCs, macOS systems, Unix workstations, Sun servers, and Linux machines without requiring platform-specific drivers or configuration.

  • Plug-and-play operation
  • No operating system restrictions
  • Works with legacy and modern systems

Deployment / Use Cases

This KVM extender transmitter is ideal for environments where computer equipment must be located at a distance from user workstations or control points. The 400-foot extension capability makes it suitable for data centers where servers are in separate rooms, industrial control systems where computers are in protected enclosures, and educational facilities where instructor stations need to manage student lab computers from a central location.

The unit's TAA compliance ensures it meets government procurement requirements, while its environmentally friendly design supports sustainable IT initiatives. Deployment scenarios typically involve pairing this transmitter with a compatible receiver unit to create a complete extension solution between the computer location and the user workstation.

Data Center Management

Enables technicians to access servers in hot aisles or secure rooms from climate-controlled workstations without entering the equipment area, improving both comfort and security.

Control Room Integration

Allows operators to interact with computers located in equipment racks or separate technical spaces while maintaining a clean, organized control room environment free of computer noise and heat.

FAQ

What type of cable does this KVM extender transmitter require for operation?

The ACX1MT-U23-C transmitter uses standard CATx network cabling (such as CAT5e, CAT6, or CAT6a) to extend signals up to 400 feet. This common cabling type is widely available and typically already installed in many IT environments, making deployment straightforward without requiring specialized fiber optic or proprietary cables.

How many computers can this single transmitter unit support simultaneously?

This transmitter is designed to support one computer per unit. It extends the keyboard, video, and mouse signals from a single computer source to a remote location. For multiple computer extensions, additional transmitter units would be required, typically configured within a modular KVM extension system.

What is the maximum USB data transfer speed supported by this extender?

The transmitter maintains full USB 2.0 specification performance with a maximum data transfer rate of 480 Mbps across its entire 400-foot operating distance. This ensures peripheral devices like external storage, cameras, and input devices function at their designed speeds without performance degradation due to the extension.

What does TAA compliance mean for this product?

TAA (Trade Agreements Act) compliance indicates that this product meets U.S. government procurement requirements for products used in federal contracts. This certification ensures the extender is manufactured in or substantially transformed in a designated country, making it eligible for purchase by government agencies, educational institutions, and other organizations with TAA procurement requirements.

Is a receiver unit required to use this transmitter, and what distance can it achieve?

Yes, this transmitter requires a compatible receiver unit to complete the extension circuit. The transmitter sends signals from the computer location, while the receiver unit connects at the user workstation location. Together, they achieve the specified maximum operating distance of 400 feet (121920 mm) when using appropriate CATx cabling between them.

What connectivity or interface options are available?

Connectivity support is listed in the product specifications, including the relevant wireless or port options when available.
