Vertiv HMX6200T-001 Dual DVI-D QSXGA KVM Extender Transmitter
Overview
The Vertiv HMX6200T-001 is the transmitter unit of the Avocent HMX 6000 series — a dual-head DVI-D KVM extender built for secure, high-resolution workstation extension in government, defense, broadcast, and enterprise control room environments. It supports QSXGA resolution (2560x1600 at 60Hz) over either CATx copper at up to 330 feet (100 m) or single-mode fiber at up to 6.2 miles (10 km) via an integrated SFP port, giving you the flexibility to deploy across a workbench, across a building, or across a campus without swapping hardware. NIAP certification means it clears the bar for classified or sensitive network environments where uncertified peripherals are a non-starter.
The HMX6200T-001 (often searched as HMX6200T 001) is a transmitter-only unit — the matching receiver is purchased separately, which lets you pair it with the receiver configuration that fits your specific endpoint needs. If you're building out a KVM extender infrastructure across multiple operator stations, the separate Tx/Rx purchase model makes per-seat scaling straightforward.
Key Features
- Dual-Head DVI-D Dual Link at 2560x1600 / 60Hz: Running two displays at full QSXGA resolution simultaneously is the headline spec here. For control room operators managing multi-screen workstations — think traffic management, broadcast production, or command-and-control — this means both screens stay at native resolution with no compression artifacts or frame drop. DVI-D dual link supports the full bandwidth needed for 30-bit color at this resolution.
- Dual Transport: CATx (330 ft) + SFP Fiber (6.2 miles): A single unit carries both copper and fiber interfaces. At 330 feet over standard CATx, it covers most in-building runs comfortably. Flip to the SFP port and that ceiling jumps to 6.2 miles — enough to extend a workstation from a secured machine room to a remote operator desk in a separate facility over a dark fiber run. You're not buying two different products for two different distances.
- USB 2.0 HID and Mass Storage: USB support covers keyboards, mice, and USB mass storage devices — not just basic HID. This is meaningful in environments where operators need to read from or write to USB drives at the remote end without physically accessing the host machine. Confirm your receiver supports the same USB profile before assuming full mass-storage pass-through at both ends.
- Bidirectional RS232 Serial: The built-in RS232 port extends serial control alongside the video and USB signals. For AV control systems, serial-controlled displays, or legacy industrial equipment that still speaks RS232, this eliminates the need for a separate serial extender running alongside your KVM run.
- 3.5mm Audio In/Out: Stereo audio — both directions — travels with the video signal. Operators at the remote end get full audio from the host and can feed a microphone or line input back. No separate audio extender needed, no synchronization headaches between audio and video paths.
- NIAP Certification: The HMX 6000 series carries NIAP certification, which is a procurement requirement — not a nice-to-have — in U.S. federal, DoD, and intelligence community deployments. If your project spec sheet calls for NIAP-certified peripherals, this box clears that requirement. If your deployment is purely commercial, NIAP is a security assurance bonus rather than a mandate.
- Rack-Mount and VESA Mount Kit Compatibility: The unit supports both rack-mount and VESA mount kit options, so it can live in a standard equipment rack alongside other AV or KVM gear, or mount directly behind a display at the transmitter location. This matters in space-constrained control rooms where every rack unit counts.
Integration and Compatibility
The HMX6200T-001 operates within the Vertiv Avocent HMX 6000 product family. The transmitter connects to the source computer via DVI-D Dual Link, USB, 3.5mm audio, and RS232 — all standard interfaces that don't require drivers on the host. The Ethernet port and SFP port provide the two transport options; only one is active per deployment depending on your cabling infrastructure.
Because the SFP slot accepts standard small form-factor pluggable modules, you have flexibility in fiber type selection (single-mode vs. multimode) and reach, provided the module spec aligns with the receiver. Verify SFP module compatibility with Vertiv's HMX 6000 documentation before sourcing third-party optics — SFP interoperability is not universal across KVM extender platforms.
For environments building out centralized KVM infrastructure, the HMX 6000 series supports matrix switching configurations. Pairing this transmitter with a compatible KVM switch or matrix enables multi-user, multi-target deployments where multiple operators share access to multiple source computers over the same extended fabric. That said, matrix-mode compatibility and licensing depend on the specific receiver and switch models in use — confirm before specifying.
USB mass storage pass-through requires attention at the receiver side. Not all KVM extender receivers handle mass storage at the same level as HID-only devices; data transfer rates over extended links are also inherently lower than a direct USB connection, which matters for large file operations.
Frequently Asked Questions
Q: Does the HMX6200T-001 require a separate receiver unit?
A: Yes. The HMX6200T-001 is the transmitter (Tx) unit only. A compatible HMX 6000 series receiver must be purchased separately to complete the extension link.
Q: What is the maximum extension distance for the HMX6200T-001?
A: Over CATx copper cabling, the maximum extension distance is 330 feet (100 m). Via the SFP fiber port, extension reaches up to 6.2 miles (10 km), making it suitable for inter-building or campus-wide deployments over dark fiber.
Q: Is the HMX6200T-001 NIAP certified?
A: Yes. The HMX 6000 series carries NIAP certification, making it suitable for U.S. federal, DoD, and other government deployments that require certified KVM and extension hardware for sensitive or classified environments.
Q: What video resolution does the HMX6200T-001 support?
A: The HMX6200T-001 supports QSXGA resolution — 2560x1600 — at 60Hz via dual-head DVI-D Dual Link. Both connected displays can run at full native resolution simultaneously.
Q: Does the HMX6200T-001 support USB mass storage or only keyboard and mouse?
A: USB 2.0 support includes both HID devices (keyboard and mouse) and USB mass storage. Verify that the paired receiver also supports mass storage pass-through, as USB capability can vary between receiver models in the HMX 6000 family.
Q: Can the HMX6200T-001 use third-party SFP modules?
A: The SFP slot accepts standard pluggable optic modules, but SFP interoperability is not guaranteed with all third-party modules. Consult Vertiv's HMX 6000 compatibility documentation before sourcing non-Vertiv SFP optics to avoid link issues.
The HMX6200T-001 is the transmitter half of Vertiv's HMX 6000 dual-head DVI extension platform, and the spec that sets it apart from most KVM extenders in this class is the combination of 2560x1600 QSXGA resolution on two simultaneous outputs with a transport-agnostic design — copper to 330 feet, fiber to 6.2 miles, same hardware, same configuration.
Technical Highlights:
- Dual Transport (CATx + SFP): Having both a CATx Ethernet port and an SFP slot on the same transmitter means you can spec this unit without knowing your cabling plant in advance — or deploy the same model across sites with different infrastructure. The 10 km fiber ceiling is sufficient for most inter-building enterprise or government campus runs.
- QSXGA Dual-Head at 60Hz: 2560x1600 per display, two displays, 60Hz — this is the resolution ceiling for dual-link DVI, and the HMX 6000 hits it. Operators running GIS, broadcast monitoring, or multi-application control room layouts get the full pixel budget without resolution compromise at the remote end.
- NIAP Certification: In federal procurement, NIAP is often a hard gate. The HMX6200T-001 clears that gate, which means it can be specified into classified or sensitive compartmented environments where uncertified extension hardware is simply disqualified regardless of technical capability.
Deployment Considerations:
- This is a transmitter-only purchase. Budget and lead time for the matching HMX 6000 series receiver from the outset — the link does nothing without both ends. Confirm receiver model compatibility, particularly USB mass storage support, before finalizing the BOM.
- SFP module selection matters. The slot is standard form factor, but Vertiv's interoperability list for the HMX 6000 should be consulted before ordering third-party optics. A mismatched or unsupported module will prevent the fiber link from negotiating, and troubleshooting SFP compatibility issues on an installed run is avoidable pain.
The HMX6200T-001 is the right call for dual-display 2560x1600 workstation extension in NIAP-gated environments — specifically defense operations centers, intelligence community workstations, and broadcast master control rooms where operator screens need to sit physically separated from the compute hardware over runs that exceed what CATx alone can handle.
