Vertiv HMX6200TH-400 Dual HDMI USB Audio SFP KVM Transmitter
Overview
The Vertiv HMX6200TH-400 is the transmitter half of the HMX 6000 KVM extension system — a dual-head HDMI, USB 2.0, and audio extender built for data centers, broadcast control rooms, and secure operations environments where the workstation and the operator cannot share the same physical space. It pushes resolutions up to 2560x1600 @ 60Hz (or two independent 1920x1200 @ 60Hz streams simultaneously) across a standard 1GbE IP network, reaching up to 100 meters over CATx or 10 kilometers over fiber via its two SFP ports. If your infrastructure requires separating compute from display by more than a rack length — or by a building — the HMX6200TH-400 is the unit that lives at the source end. Note: receiver units are purchased and deployed separately.
Key Features
- Dual-Head HDMI at Full Resolution: Drives a single display at 2560x1600 @ 60Hz or two independent 1920x1200 @ 60Hz outputs simultaneously. For broadcast operators or trading floors running multi-monitor workstations, this means the remote operator sees the same pixel-perfect image the console produces — no downscaling, no compromises on refresh rate.
- Two SFP Ports for Maximum Reach and Flexibility: The pair of SFP link ports accept either CATx modules (up to 100m) or fiber modules (up to 10km), giving the HMX6200TH-400 (often searched as HMX6200TH 400) the range to span a campus or reach a remote operations center across a fiber backbone. Most single-port extenders force a topology decision at purchase; the dual-SFP design here lets you mix media types or configure redundant paths.
- 1GbE IP Network Transport: Riding standard Gigabit Ethernet means no proprietary switching fabric. The transmitter connects into your existing managed network infrastructure — controlled via VLANs, monitored by your NMS, and routed the same way any other IP device would be. No dedicated KVM cabling plant to design or maintain.
- 256-bit AES + RSA 2048 Encryption: All video, USB, and audio traffic between transmitter and receiver is encrypted end-to-end. For government, defense, financial, and healthcare environments where unencrypted KVM traffic over a shared network is a compliance non-starter, this removes the security objection entirely. RSA 2048 handles key exchange; AES-256 handles the session payload.
- USB 2.0 Extension: Full USB 2.0 support means keyboards, mice, CAC readers, and low-speed peripherals at the receiver end communicate with the source machine over the same IP link. No separate USB extension infrastructure needed for standard HID and identity devices.
- Audio Transport Included: Analog audio is carried alongside video and USB on the same network path. Operators working in environments where audio monitoring matters — dispatch centers, broadcast, or video production — don't need a parallel audio distribution system.
- Up to 16 Simultaneous Users: The HMX 6000 system supports up to 16 users accessing connected sources simultaneously. For shared-access control rooms or collaborative operations environments, this scales well beyond what a point-to-point extender can offer.
- Power Adapter Included: The unit ships with its power adapter, so there are no separate accessory orders required to commission the transmitter. One less line item in the deployment BOM.
Integration and Compatibility
The HMX6200TH-400 operates over a standard 1GbE IP network, which means it integrates into any managed switch infrastructure without vendor-specific hardware. The dual SFP ports accept standard CATx or fiber transceiver modules, giving your network team the flexibility to match the existing cabling plant. The system's multi-user architecture — up to 16 simultaneous users — makes it compatible with matrix switching deployments where multiple operators share access to multiple sources. Receiver units must be procured separately; the transmitter is designed to pair with the corresponding HMX 6000 receiver within the Vertiv Avocent HMX product family. For organizations running KVM extenders as part of a broader AV-over-IP or KVM over IP architecture, the HMX6200TH-400 fits naturally into a managed VLAN topology. Those planning larger matrix deployments should also review compatible matrix switch options within the Vertiv infrastructure catalog. For environments building out video-over-IP distribution alongside KVM, the SFP-based transport aligns with the same fiber backbone already in use.
Frequently Asked Questions
Q: Does the HMX6200TH-400 include the receiver unit?
A: No. The HMX6200TH-400 is the transmitter unit only. The corresponding HMX 6000 receiver must be purchased separately to complete the extension link.
Q: What is the maximum extension distance supported by the HMX6200TH-400?
A: Up to 100 meters over CATx and up to 10 kilometers over fiber, using the appropriate SFP modules in the unit's two SFP ports.
Q: What video resolutions does the HMX6200TH-400 support?
A: The transmitter supports a single display at up to 2560x1600 @ 60Hz, or two independent displays at up to 1920x1200 @ 60Hz simultaneously via dual HDMI outputs.
Q: What encryption does the HMX6200TH-400 use?
A: The HMX6200TH-400 encrypts all traffic using 256-bit AES for session data and RSA 2048 for key exchange, covering video, USB, and audio streams between transmitter and receiver.
Q: How many users can simultaneously access a source connected to the HMX6200TH-400?
A: The HMX 6000 system supports up to 16 simultaneous users, making it suitable for shared-access control rooms and collaborative operations deployments.
Q: What network infrastructure does the HMX6200TH-400 require?
A: The unit operates over a standard 1GbE IP network. No proprietary switching fabric is needed — it integrates into existing managed Gigabit Ethernet infrastructure, controllable via standard VLAN and network management tools.
The spec I keep coming back to on the HMX6200TH-400 is the 10km fiber reach. In the average enterprise KVM deployment, 100 meters of CATx is plenty — but the moment a customer is separating a secure compute room from a remote operations center across a campus fiber backbone, CATx-only extenders become a dead end. The dual SFP architecture here handles both scenarios from the same unit, which simplifies the procurement story considerably when topology isn't fully locked down at purchase time.
Technical Highlights:
- Dual-Head HDMI at 2560x1600: Delivers either a single 2560x1600 @ 60Hz feed or two simultaneous 1920x1200 @ 60Hz streams — covering virtually every multi-monitor workstation configuration used in broadcast, dispatch, and trading environments without requiring a separate splitter or scaler.
- 256-bit AES + RSA 2048 Encryption: End-to-end encryption across all IP-transported streams (video, USB, audio) satisfies the security posture required in government and financial deployments where unencrypted KVM traffic over shared network segments is a hard compliance failure.
- 16-User Simultaneous Access: Unlike a point-to-point extender that locks one operator to one source, the HMX 6000 system's multi-user architecture lets up to 16 operators share access — the right foundation for a matrix-switched control room rather than a fixed 1:1 deployment.
Deployment Considerations:
- The HMX6200TH-400 is a transmitter-only unit — budget and procure the matching HMX 6000 receiver separately before commissioning. Plan the receiver order at the same time to avoid project delays.
- SFP modules are not specified in the evidence as included — confirm which CATx or fiber SFP transceivers are compatible with the HMX 6000 family before finalizing the cabling BOM, especially for 10km single-mode fiber runs.
This transmitter is the right fit for a multi-monitor broadcast control room or a secure government operations environment where operators need pixel-accurate 2560x1600 display extension over an existing fiber backbone, with encryption requirements that preclude unprotected KVM-over-IP solutions.
