Black Box ACX1MR-DHID-SM DKM Extender Receiver Module
Overview
The Black Box ACX1MR-DHID-SM is a receiver module in the DKM extender family, engineered to support the widest range of possible signal extension combinations within the DKM platform. The DKM architecture is a modular approach to KVM and AV-over-IP extension, allowing integrators to mix and match transmitter and receiver cards to suit specific signal types, distances, and switching requirements — without being locked into a fixed point-to-point topology.
If you are building or expanding a DKM matrix system and need a receiver card that accommodates flexible input combinations, the ACX1MR-DHID-SM is positioned as the broadest-compatibility option in the DKM receiver lineup. Verify current slot and chassis compatibility with your DKM matrix chassis before ordering, as modular receiver cards are chassis-dependent.
Key Features
- Widest Combination Range: The ACX1MR-DHID-SM is designed to support the widest range of possible DKM signal combinations — useful in control rooms or broadcast environments where sources and destinations vary across a single installation.
- Modular DKM Architecture: Slots into the Black Box DKM matrix chassis, meaning you can scale the system by adding receiver cards rather than replacing entire extender units — a practical cost control for phased deployments.
- Black Box DKM Ecosystem: Part of the broader Black Box DKM extender and matrix switching line, which covers a range of signal types and extension distances for enterprise AV and KVM distribution.
Integration and Compatibility
The ACX1MR-DHID-SM is designed for use within the Black Box DKM matrix switching ecosystem. Before deploying, confirm chassis model compatibility, firmware revision requirements, and which transmitter cards are validated for pairing with this receiver. For installations involving KVM switching or AV-over-IP distribution, the DKM platform supports centralized management of multiple sources and destinations from a single matrix chassis. Consult the Black Box DKM extender product line for the full range of compatible transmitter modules and chassis options.
Frequently Asked Questions
Q: What does the ACX1MR-DHID-SM receiver module do?
A: The ACX1MR-DHID-SM is a receiver card in the Black Box DKM extender family, designed to support the widest range of signal extension combinations within the DKM modular matrix platform.
Q: Is the ACX1MR-DHID-SM a standalone device or does it require a chassis?
A: It is a modular receiver card and requires a compatible Black Box DKM matrix chassis to operate. It is not a standalone extender unit.
Q: What signal types does the ACX1MR-DHID-SM support?
A: Full signal-type specifications are not confirmed in the available evidence. Contact pre-sales engineering for a validated compatibility list before ordering.
Q: Where can I find the DKM chassis models compatible with the ACX1MR-DHID-SM?
A: Compatibility details are available through the Black Box DKM product documentation. Confirm chassis model and firmware version with your reseller or Black Box directly before deployment.

The ACX1MR-DHID-SM sits in the receiver slot of the Black Box DKM matrix — the key spec the manufacturer highlights is its support for the widest range of possible DKM signal combinations, which matters in mixed-environment control rooms where you cannot standardize on a single signal type across all sources. That flexibility is the product's primary selling point within the DKM line.
Technical Highlights:
- Widest Combination Range: Designed to accommodate the broadest set of DKM transmitter pairings — reduces the need to stock multiple receiver SKUs when signal types vary across a deployment.
- Modular Slot Design: Installs into a DKM matrix chassis rather than operating as a standalone unit — enables per-port upgrades without chassis replacement, which controls cost in phased build-outs.
- DKM Ecosystem Integration: Operates within the Black Box DKM switching architecture, supporting centralized source-to-destination management across a single matrix platform.
Deployment Considerations:
- Chassis compatibility must be verified before ordering — not all DKM chassis generations support every receiver card, and firmware revisions can affect slot compatibility.
- Available evidence does not confirm specific signal types (DisplayPort, HDMI, fiber distance) for this SKU — request the Black Box DKM compatibility matrix from your pre-sales contact before finalizing the BOM.
The ACX1MR-DHID-SM is best suited for control room or broadcast environments running a heterogeneous DKM matrix where signal-type flexibility at the receiver slot is a hard requirement — not a deployment where a fixed signal type makes a simpler, lower-cost card the better call.
