Black Box ACX1R-22-C Dual-Display Compact KVM Extender Receiver

The Black Box ACX1R-22-C is the dual-head receiver unit in Black Box's ACX1000 Series compact KVM extender system — purpose-built for installations where a workstation must drive two displays from a remote location over structured cabling or fiber. The ACX1R-22-C pairs with a compatible ACX transmitter to extend dual-video, USB HID, and audio signals beyond the reach of direct cabling, without signal degradation or latency that would compromise operator workflows.

The ACX1000 Series targets control rooms, broadcast environments, secure operations centers, and industrial facilities where computing hardware must be locked away in a secure or climate-controlled enclosure while operators work at ergonomic, human-accessible stations. For a full overview of compatible transmitters and system configurations, see the Black Box catalog.

Key Features

• Dual-Display Extension: The "22" designation in ACX1R-22-C confirms dual-video output — two monitors at the remote receiver desk. This eliminates the need to run two separate extender pairs for a dual-screen workstation, reducing cabling complexity and switch port consumption.
• 1920×1200 Resolution Support: Full WUXGA resolution across both outputs means operators get full desktop real estate without downscaling — important for detailed applications like CAD, video walls, or multi-pane security monitoring dashboards.
• USB HID Pass-Through: Keyboard and mouse signals travel transparently over the extension link, so the remote operator experience is indistinguishable from sitting at the host machine. No special drivers required at the receiver end.
• Audio Extension: Analog audio is carried alongside video and USB, supporting headset-equipped operator stations without a separate audio distribution system.
• CATx and Fiber Flexibility: The ACX1000 Series supports both copper CATx and fiber interconnects depending on the transmitter/receiver variant selected. CATx reaches up to 100m — sufficient for most in-building runs. Fiber variants extend the link to 10km or beyond, covering campus or inter-building deployments. Confirm the specific cable plant this SKU supports against your infrastructure before ordering.
• Compact Form Factor: The "C" suffix denotes the compact chassis — designed for space-constrained receiver desks, under-monitor mounting, or shallow rack environments. This matters in dense control rooms where every inch of desk real estate is contested.

Integration and Compatibility

The ACX1R-22-C is designed to operate within Black Box's ACX KVM extender ecosystem. It requires a matched ACX transmitter (sold separately) — verify transmitter model compatibility before ordering to ensure the video interface, cable plant type, and feature set align. The system is compatible with standard USB HID peripherals; USB 2.0 devices beyond keyboard and mouse (such as USB drives or webcams) may require a variant with full USB 2.0 extension support — confirm against the ACX1R-22-C datasheet. Integration with KVM switches or matrix switching environments is possible; review the ACX series compatibility matrix for multi-user or multi-target configurations. For PoE switch planning in broader AV-over-IP or control room infrastructure, see the PoE switch selection guide.

Deployment Context

This receiver is best suited to fixed operator station deployments — control rooms, security NOCs, broadcast production desks, and industrial HMI stations — where the host CPU is rack-mounted in a separate IDF or server room. If you need to extend to a single-display station, consider a single-head receiver in the same ACX family. If your environment demands 4K/UHD resolution, evaluate whether the ACX1000 Series meets that requirement or whether a higher-tier ACX model is appropriate for the display spec. For guidance on structuring a full KVM extender system, including transmitter selection and cable plant planning, review the ACX series configuration guide from Black Box.

Frequently Asked Questions

Q: What transmitter does the ACX1R-22-C pair with?

A: The ACX1R-22-C is the receiver unit in Black Box's ACX1000 Series and requires a compatible ACX transmitter (sold separately). Match the transmitter to the same cable plant type (CATx or fiber) and video interface. Consult the ACX series compatibility matrix to confirm the correct transmitter SKU for your configuration.

Q: Does the ACX1R-22-C support 4K resolution?

A: The ACX1000 Series is documented to support up to 1920×1200 (WUXGA). If your displays or application require 4K/UHD output, evaluate higher-tier models in the Black Box ACX lineup before ordering.

Q: Can I use the ACX1R-22-C with a KVM switch for multi-user or multi-target environments?

A: The ACX1000 Series can be integrated with compatible KVM switches for matrix or multi-user deployments. Verify switch compatibility against the ACX series documentation, as not all KVM switch models support transparent integration with this extender family.

Q: What cable type does the ACX1R-22-C use for the extension link?

A: The ACX1000 Series supports CATx structured cabling (up to approximately 100m) or fiber (for longer runs). The specific cable plant supported by this SKU should be confirmed against the Black Box ACX1R-22-C datasheet, as the suffix letters in the model number indicate the variant.

Q: Does the ACX1R-22-C include audio support?

A: Yes, the ACX1000 Series receiver extends analog audio alongside video and USB HID signals, supporting headset-equipped operator stations without a separate audio infrastructure.

Q: Is the ACX1R-22-C TAA or NDAA compliant?

A: TAA and NDAA compliance status for the ACX1R-22-C should be confirmed directly against the current Black Box product documentation or your procurement channel, as compliance designations can change with component revisions.

The ACX1R-22-C is the piece of the ACX1000 puzzle that sits at the operator desk — the dual-display receiver that makes a remotely-racked workstation feel local. The dual-head design is the spec that matters most here: extending two independent video outputs, USB HID, and audio over a single structured-cabling run is a real wiring savings compared to deploying two single-head extender pairs for a dual-monitor station. If you're outfitting a control room or NOC where operators need two screens and the CPU has to live in a secure rack room down the hall, this is the receiver-side unit to specify.

Technical Highlights:

• Dual-Head Output: Two independent display outputs at the receiver — extending full WUXGA (1920×1200) to each monitor. Operators get the same desktop real estate as sitting at the host machine, no resolution compromise.
• USB HID Pass-Through: Keyboard and mouse travel transparently over the extension link. No receiver-side drivers, no input lag perceptible to the operator — critical for production-speed workflows in broadcast or security operations environments.
• Audio Extension: Analog audio rides the same link as video and HID, so headset-equipped stations don't need a separate audio distribution run — one cable plant, full A/V/control signal set.

Deployment Considerations:

• The ACX1R-22-C is a receiver only — it requires a matched ACX transmitter at the host end. Verify the transmitter SKU before ordering; mismatched variants (wrong cable plant type or video interface) will not interoperate.
• If your deployment demands USB 2.0 device extension beyond keyboard and mouse (smart card readers, USB audio, webcams), confirm the ACX1R-22-C specifically supports full USB 2.0 pass-through rather than USB HID only — not all ACX1000 variants include it.

This receiver is the right call for dual-screen operator stations in security NOCs, broadcast production suites, and industrial control rooms where the host CPU must be physically separated from the operator — and where running two separate extender pairs per desk would create unnecessary cable and port overhead. Specify it alongside the correct ACX transmitter and your chosen cable plant (CATx for in-building runs up to 100m, fiber for inter-building).
