Vertiv HMX6200TDP-400 Dual DisplayPort USB Audio SFP KVM Transmitter

Overview

The Vertiv HMX6200TDP-400 is the transmitter unit in the Avocent HMX 6000 series — a high-performance KVM extension platform purpose-built for environments where workstations must be physically separated from operators by meaningful distance. It extends dual-head DisplayPort video, USB 2.0, audio, and RS-232 signals over a standard 1GbE IP network using two SFP ports, giving you the choice of CATx runs up to 328 feet or fiber runs up to 6.2 miles without any video signal degradation.

This is not a consumer-grade extender. The HMX6200TDP-400 is designed for broadcast control rooms, government facilities, industrial automation environments, and secure command centers where losing video quality, introducing latency, or leaving KVM traffic unencrypted is not acceptable. Receiver units are purchased separately — plan your system accordingly.

Key Features

• Dual-Head DisplayPort at Full Resolution: Supports either a single display at 2560x1600 @ 60Hz or two displays simultaneously at 1920x1200 @ 60Hz. For traders, control room operators, or broadcast engineers running dual-monitor workstations, you get full-resolution extension without downscaling or frame-rate compromise.
• Dual SFP Ports for Flexible Media: The two SFP ports accept either CATx or fiber modules — you're not locked into one cable type. Short runs (up to 100m / 328 ft) work with CATx SFP modules; longer infrastructure needs go fiber, with range from 500m (1,640 ft) up to 10km (6.2 miles) depending on module selection. Mix as needed to fit your building's cabling plant.
• 256-bit AES + RSA 2048 Encryption: All KVM traffic — video, USB, audio, and RS-232 — is encrypted to AES-256 with RSA-2048 key exchange in transit. For government, defense, and regulated facilities where unencrypted KVM signals on the network are a compliance violation, this is the spec to document for your security team.
• 16 Simultaneous Users: The HMX 6000 architecture supports up to 16 concurrent remote users connected to the same transmitter through the IP network. This matters in NOC or operations center deployments where multiple operators need access to the same source workstation without physical presence at the machine.
• USB 2.0 Extension: Full USB 2.0 pass-through means keyboards, mice, CAC readers, and compatible peripherals on the receiver side behave exactly as if connected locally to the workstation. For environments requiring smart-card authentication at the remote operator position, this is a real-world requirement that lower-cost extenders often get wrong.
• RS-232 Serial Control: Onboard RS-232 support extends serial control alongside the KVM signals. Useful in broadcast or industrial deployments where the host workstation manages serial-connected rack equipment — you don't need a separate serial extender run.
• Audio Extension: Analog audio travels alongside video and USB in the same IP stream. No secondary audio extender needed, and no additional cabling run to the transmitter location.
• 1GbE IP Network Transport: Runs over standard Gigabit Ethernet infrastructure — no proprietary network hardware or dedicated KVM fabric required. Deploy over your existing managed switches, provided you can allocate the bandwidth and enforce QoS for the video streams.

Integration and Compatibility

The HMX6200TDP-400 is the transmitter (host-side) unit only. It pairs with a compatible HMX 6000 series receiver unit at the operator position — receivers are sold separately and must be specified for your display and peripheral configuration. The dual SFP ports accept standard small form-factor pluggable modules; select CATx or fiber SFP modules based on your run length and existing cabling. The device operates over standard 1GbE IP infrastructure, making it compatible with managed enterprise switches that support QoS configuration for latency-sensitive traffic. The RS-232 port (often searched as HMX6200TDP 400) adds serial device control integration into the same extended signal path.

For organizations managing multiple extended workstations, the HMX 6000 architecture is designed to scale — the 16-user concurrent access capability means this transmitter can serve a team of operators from a central compute location without requiring one-to-one transmitter-to-workstation mapping at every desk. Browse the full Vertiv KVM and extension catalog for compatible receiver units and management appliances.

If your operators run dual-monitor setups with DisplayPort outputs, this transmitter eliminates the need for any video conversion hardware at the host — connect directly from the workstation's DP outputs. For environments requiring KVM extenders across fiber plant, the dual SFP architecture keeps infrastructure flexible without forcing a CATx ceiling on your run lengths.

Planners building out secure control rooms should also review KVM over IP switching options to centralize access management across multiple extended workstation nodes, and evaluate KVM over IP infrastructure for multi-site operator access scenarios.

Frequently Asked Questions

Q: Does the HMX6200TDP-400 include a receiver, or is it transmitter only?

A: The HMX6200TDP-400 is the transmitter (host/workstation side) unit only. A compatible HMX 6000 series receiver unit must be purchased separately for the operator/remote side of the extension link.

Q: What is the maximum extension distance supported by the HMX6200TDP-400?

A: With CATx SFP modules, the maximum distance is 328 feet (100m). With fiber SFP modules, the range extends from 1,640 feet (500m) up to 6.2 miles (10km), depending on the specific fiber SFP module installed.

Q: What encryption does the HMX6200TDP-400 use for KVM-over-IP traffic?

A: The HMX6200TDP-400 supports up to 256-bit AES encryption with RSA 2048 key exchange, covering video, USB, audio, and RS-232 traffic traversing the IP network.

Q: Can the HMX6200TDP-400 run dual monitors, and at what resolution?

A: Yes. It supports either one display at up to 2560x1600 @ 60Hz, or two displays simultaneously at up to 1920x1200 @ 60Hz each. Both modes use DisplayPort.

Q: How many simultaneous remote users can connect through the HMX6200TDP-400?

A: The HMX 6000 architecture supports up to 16 simultaneous users connecting to the same transmitter over the IP network.

Q: What type of SFP modules does the HMX6200TDP-400 require?

A: The dual SFP ports accept standard 1GbE SFP modules — either CATx or fiber variants. The specific module determines your maximum run distance. SFP modules are not included with the transmitter unit and must be specified and purchased separately to match your cabling infrastructure.

The spec I keep coming back to on the HMX6200TDP-400 is the dual SFP architecture — not because fiber range is unusual in enterprise KVM, but because having two SFP ports on a single transmitter means you can use one for the primary IP link and one for redundancy or uplink aggregation depending on how the HMX 6000 management layer handles the ports in your deployment. That flexibility matters when you're designing a secure control room where a single-point-of-failure on the KVM fabric is a mission-critical problem, not just an inconvenience.

Technical Highlights:

• Dual-Head DisplayPort at 2560x1600: Single-display mode maxes at 2560x1600 @ 60Hz — that covers the full native resolution of most 30-inch professional monitors used in broadcast and control room environments without any downscaling. Dual-display mode steps to 1920x1200 @ 60Hz per head, which is still the native resolution of legacy 24-inch professional displays common in older NOC buildouts.
• AES-256 + RSA-2048 Encryption: Every packet — video, USB HID, audio, RS-232 — traverses the network encrypted. For classified or regulated environments where KVM traffic on a shared IP backbone needs to meet encryption minimums, 256-bit AES with RSA-2048 key management is the number to put in your security documentation.
• 16 Concurrent Users: Sixteen simultaneous operator connections to one transmitter is meaningful in shift-based operations centers where you need more than one person watching or controlling the same host at once — without purchasing a separate KVM switch layer just to enable shared access.

Deployment Considerations:

• SFP modules are not included with the HMX6200TDP-400 — budget for CATx or fiber SFP modules separately based on your actual run lengths, and verify that your selected modules are compatible with the HMX 6000 platform before ordering.
• The receiver unit is also a separate purchase; this is a transmitter-only SKU. Factor both units plus any management appliance into your BOM before quoting the project, particularly for multi-node deployments where the per-seat cost adds up quickly.

The HMX6200TDP-400 fits best in broadcast master control rooms and government operations centers where dual-monitor DisplayPort workstations need to be physically separated from operators by fiber runs — and where putting unencrypted KVM on the network simply isn't an option. If your deployment is a single short-run office environment with standard 1080p monitors, this platform is more capability than you need; but for distributed control infrastructure where resolution, security, and concurrent access all matter, the HMX 6000 transmitter is the right starting point.
