The Black Box ACX1MT-VDHID-C is a modular KVM extender transmitter designed for deployments where video, HID keyboard/mouse, and USB control signals need to be extended from a source machine to a remote operator station. As the transmitter (TX) half of a KVM extension pair, the ACX1MT-VDHID-C installs at the CPU or source end, capturing and encoding signals for transport across structured cabling to a paired receiver unit.
Black Box's modular ACX1 platform is built around a chassis-and-module architecture, meaning the ACX1MT-VDHID-C slots into a compatible ACX1 chassis rather than operating as a standalone enclosure. This approach lets integrators mix and match transmitter and receiver modules within a single chassis to support multiple independent KVM extension channels in broadcast, command-and-control, government, and secure operations center environments — without deploying a separate box per channel.
The -VDHID suffix in the ACX1MT-VDHID-C part number indicates video plus HID (Human Interface Device) support — covering standard keyboard and mouse pass-through. This makes it well suited for operator workstation extensions where peripheral compatibility and low-latency control response are priorities.
For full deployment, a compatible ACX1 receiver module and chassis are required. Consult Black Box's ACX1 product family documentation to confirm chassis compatibility, supported video resolutions, extension distances, and cabling requirements before specifying this module in a design. For a broader look at Black Box extension and KVM products, the full catalog covers both modular and standalone configurations.
If you are sourcing this module for an existing ACX1 installation or building out a new KVM extender architecture, verify receiver pairing and chassis slot availability with your design documentation. Pre-sales engineering support is available to assist with bill-of-materials validation.
Q: What does the ACX1MT-VDHID-C transmitter module do?
A: The ACX1MT-VDHID-C is the transmitter (source-end) module in a Black Box ACX1 modular KVM extension system. It captures video and HID (keyboard/mouse) signals from a local CPU or workstation and sends them over structured cabling to a paired ACX1 receiver module at the operator station.
Q: Does the ACX1MT-VDHID-C work as a standalone unit?
A: No. The ACX1MT-VDHID-C is a module designed for installation into a compatible Black Box ACX1 chassis. It requires a chassis and a paired receiver module to form a complete KVM extension link. Consult Black Box's ACX1 chassis compatibility matrix before ordering.
Q: What type of peripherals does the ACX1MT-VDHID-C support?
A: The -VDHID designation indicates support for video and HID devices — standard USB keyboard and mouse. For USB 2.0 peripheral extension beyond HID, verify whether the specific ACX1 module variant or chassis configuration supports extended USB.
Q: What receiver module pairs with the ACX1MT-VDHID-C?
A: The ACX1MT-VDHID-C is the transmitter module; a compatible ACX1 receiver module (ACX1MR series) is required at the remote end. Confirm the exact receiver pairing with Black Box's ACX1 module compatibility documentation for your chassis and cabling plant.
The ACX1MT-VDHID-C sits at the source end of a Black Box ACX1 modular KVM extension link — it's the transmitter module that captures video and HID signals from a host machine and hands them off to the cabling plant. Where I see this module specified most often is in command-and-control rooms and operations centers where the CPU farm needs to be physically separated from operator desks, and individual chassis slots are used to scale channel count without proliferating rack footprint.

Deployment Considerations:
This module is the right call for secure operations centers and government control rooms where CPU consolidation behind a locked equipment room is non-negotiable — the modular form factor keeps the operator-end desk clean and the source hardware physically isolated.
