Black Box ACX1MT-DHID-C DKM KVM Extender Transmitter Module

Overview

The Black Box ACX1MT-DHID-C is a transmitter module designed for use within Black Box's DKM KVM extension and matrix switching platform — a modular, chassis-based architecture built for control rooms, broadcast environments, and secure operations centers where operators need reliable, low-latency access to distributed computing sources.

The DKM platform separates the user workstation from the host computer, allowing IT and AV teams to consolidate servers and workstations in a secure, climate-controlled machine room while operators interact from remote endpoints across the facility. The ACX1MT-DHID-C slots into a DKM chassis and handles the transmitter (source) side of that signal path — connecting to the host computer and presenting its video, USB HID, and related signals onto the DKM matrix backplane or CATx/fiber link.

Because the ACX1MT-DHID-C (often searched as ACX1MT DHID C) is a modular component, it is specified and deployed as part of a complete DKM system rather than as a standalone device. Confirm chassis compatibility, required receiver modules, and the specific signal types (DisplayPort, HDMI, DVI, USB HID) supported by this card before ordering — Black Box's DKM line spans multiple card generations and interface standards, and module interoperability depends on matching transmitter and receiver generations within the same chassis family.

Key Considerations Before Ordering

• Chassis dependency: This module requires a compatible Black Box DKM chassis to operate. It does not function as a standalone extender — verify your chassis model and available slots before purchasing.
• Receiver pairing: A matched DKM receiver module on the endpoint side is required to complete the extension path. Confirm the receiver SKU is compatible with the ACX1MT-DHID-C transmitter generation.
• Signal type: The DHID designation in the part number indicates this module handles digital video (DisplayPort or HDMI, depending on generation) plus USB HID — confirm the exact interface matches your source computer's output ports.
• Scalability: The DKM platform supports multi-user, multi-source matrix configurations. If you're building out a control room with multiple operators and sources, plan your chassis slot count and switching licenses accordingly.

Frequently Asked Questions

Q: What chassis is the ACX1MT-DHID-C compatible with?

A: The ACX1MT-DHID-C is a modular transmitter card designed for Black Box DKM chassis systems. Confirm the specific chassis model with Black Box or your integrator to ensure slot and generation compatibility before ordering.

Q: Does the ACX1MT-DHID-C work as a standalone extender?

A: No. This is a transmitter module that requires installation in a compatible DKM chassis and a paired receiver module at the endpoint. It is not a self-contained point-to-point extender.

Q: What does the DHID designation mean in the part number?

A: The DHID suffix indicates the module supports digital video (D) and USB HID (HID) signal types. The specific video interface (DisplayPort or HDMI) depends on the module generation — verify with the product datasheet.

Q: Can the ACX1MT-DHID-C be used in a matrix switching configuration?

A: Yes. The DKM platform supports matrix configurations where multiple transmitter and receiver modules are interconnected, allowing any operator endpoint to access any source. Scaling requires sufficient chassis capacity and appropriate switching licenses.

Q: Is pre-sales engineering support available for DKM system design?

A: Yes. Pre-sales engineering is available to help size the chassis, confirm module compatibility, and map out the full DKM topology for your control room or operations center deployment.

The ACX1MT-DHID-C sits on the transmitter (source) side of Black Box's DKM matrix — it's the card that connects your host workstation or server to the chassis backplane, and getting that pairing right matters more than most integrators expect when they're first speccing a DKM system.

Technical Highlights:

• Digital video + USB HID in a single module: The DHID designation confirms this card handles both the display signal and keyboard/mouse HID traffic in one slot — that consolidation keeps your chassis slot budget manageable in dense multi-source deployments.
• Modular chassis architecture: Because the ACX1MT-DHID-C installs into a DKM chassis rather than operating standalone, you get the flexibility to mix transmitter types across slots — useful when your source pool includes machines with different video outputs across a single chassis.
• Matrix-ready by design: The DKM platform scales to full any-to-any matrix switching. This transmitter module participates in that fabric, meaning a single ACX1MT-DHID-C source can be routed to multiple receiver endpoints simultaneously once the chassis and licensing are in place.

Deployment Considerations:

• Confirm the exact DKM chassis generation before ordering — Black Box has released multiple DKM chassis families and not all transmitter cards are cross-compatible across generations. A mismatch here means the module won't initialize.
• The -C suffix in the part number typically denotes a specific connector or configuration variant within the DKM line. Do not substitute with a non-C variant assuming equivalence — verify with the Black Box compatibility matrix for your chassis.

The ACX1MT-DHID-C is the right transmitter card for control room integrators building out a DKM matrix where the source machines output digital video with USB HID peripherals — particularly in broadcast, utility SCADA, or secure operations environments where operator-to-source flexibility and physical machine room isolation are both requirements.
