Black Box ACX1MT-HDM2-C Modular KVM Extender Transmitter

Overview

The Black Box ACX1MT-HDM2-C is a transmitter module designed for the Black Box ACX1000 Series Modular KVM Extender platform. Modular KVM extender architectures let you mix and match transmitter and receiver cards to match each workstation's exact I/O requirements — rather than replacing a fixed-configuration unit when requirements shift, you swap or add modules. The ACX1MT-HDM2-C slots into the ACX1000 chassis and handles the HDMI 2.0 signal path on the transmitter side, sending video and control signals over your chosen transport medium to a paired receiver module. If you are building or expanding a KVM extender deployment and need HDMI 2.0 transmitter capability specifically, this module is the field-replaceable unit to evaluate.

Key Features

• Modular form factor: Slots into the ACX1000 chassis rather than requiring a standalone unit — reduces per-seat cost when only one signal type needs to change, and simplifies sparing strategies since a single module card can restore a failed transmitter without swapping an entire appliance.
• HDMI 2.0 signal support: The HDM2 designation in the part number indicates HDMI 2.0 compatibility on the transmitter side, supporting the higher bandwidth required for 4K/UHD sources compared to HDMI 1.4 variants — relevant when source workstations drive 4K displays or high-refresh content.
• Transmitter role: This is the local-end (TX) module; a compatible ACX1000-series receiver module is required at the remote end to complete the extension link. Confirm receiver compatibility and transport type (fiber or copper) with Black Box before ordering.
• Platform consistency: Deploying within the ACX1000 ecosystem means firmware updates, management, and sparing all operate under a single platform — useful in KVM infrastructure environments where standardization lowers operational overhead.

Integration and Compatibility

The ACX1MT-HDM2-C is designed for use within the Black Box ACX1000 Modular KVM Extender series. Pairing requires a compatible ACX1000-series receiver module and chassis. Transport medium (single-mode fiber, multimode fiber, or CATx copper) depends on the chassis and paired receiver configuration — verify your specific extension distance and transport requirements against the cabling infrastructure already in place. Contact pre-sales engineering to confirm chassis compatibility and receiver pairing before placing an order.

Frequently Asked Questions

Q: What chassis does the ACX1MT-HDM2-C install into?

A: The ACX1MT-HDM2-C is a module designed for the Black Box ACX1000 Series Modular KVM Extender chassis. Confirm chassis compatibility with Black Box or your pre-sales contact before ordering.

Q: Does the ACX1MT-HDM2-C support 4K resolution?

A: The HDM2 designation indicates HDMI 2.0 signal support, which carries the bandwidth required for 4K/UHD sources. Verify the maximum supported resolution against the current Black Box datasheet for confirmed specifications.

Q: Is a receiver module included with the ACX1MT-HDM2-C?

A: No — the ACX1MT-HDM2-C is the transmitter (local/TX) module only. A separate compatible ACX1000-series receiver module is required at the remote end to complete the extension link.

Q: What transport media does the ACX1MT-HDM2-C support?

A: Transport medium (fiber or copper) is determined by the chassis and paired receiver configuration, not the transmitter module alone. Consult the ACX1000 platform documentation to match transport type to your extension distance requirements.

Q: Can the ACX1MT-HDM2-C be used as a standalone extender?

A: No. It is a modular card that requires installation in an ACX1000-series chassis and must be paired with a compatible receiver module. It does not function as a standalone unit.

Karl Wilson

The ACX1MT-HDM2-C is the transmitter card you reach for when you are building out an ACX1000-series modular KVM deployment and need HDMI 2.0 on the local end. The HDM2 designation is the key differentiator from HDMI 1.4 variants in the same family — if your source workstations are pushing 4K content, you need this card, not the HDM1 equivalent.

Technical Highlights:

• HDMI 2.0 transmitter module: Supports the higher bandwidth envelope of HDMI 2.0 versus 1.4, making it the correct module when source signals exceed 1080p or run at elevated refresh rates that saturate HDMI 1.4 bandwidth.
• Modular chassis architecture: Because the ACX1000 platform separates the chassis from the signal cards, you can field-replace just this transmitter module if it fails — no need to swap the entire extender unit or reprovision a fixed-configuration appliance.
• TX-only role: This module handles the local/source side of the extension link exclusively. Pairing with the correct ACX1000-series receiver module is mandatory — mismatched receiver variants are the most common ordering error on modular KVM platforms.

Deployment Considerations:

• Confirm the target ACX1000 chassis slot count and available module bays before ordering — the transmitter card occupies a physical slot, and chassis capacity limits how many concurrent extension links you can run per unit.
• Transport distance and medium (fiber vs. CATx) are governed by the chassis and receiver pairing, not this transmitter card alone — map your cable runs and distance requirements before selecting the receiver-side module to complete the link.

The ACX1MT-HDM2-C is the right specification for broadcast control rooms, secure government workstation deployments, or post-production suites where 4K HDMI sources need to reach remote operator positions via an ACX1000-series chassis — and where the ability to swap a single card without pulling the entire extender unit is operationally important.
