StarTech USB3004EXT2 4-Port USB 3.0 Extender Hub over RJ45

Overview

The StarTech USB3004EXT2 solves a problem that comes up constantly in surveillance deployments, kiosk installations, and distributed AV setups: you need USB 3.0 connectivity at a remote location, but running USB cable directly from a host PC simply isn't viable past 5 meters. This extender system pushes SuperSpeed USB 3.0 at up to 5 Gbps across up to 100 meters (328 feet) of Cat 6a or better structured cabling — the same infrastructure already in most commercial buildings — delivering four USB Type-A ports at the far end without any active management overhead on the host side.

The kit ships as two units: a local transmitter that connects to your host PC via a USB 3.2 Type-B port, and a remote receiver that presents four full-speed USB extension ports to whatever devices are stationed there. Both units are housed in an aluminum chassis, draw power from the included AC adapters (100–240V input, universal for international sites), and communicate status through eight onboard LED indicators — two per function across power, status, link, and USB activity.

Key Features

• 100m reach over Cat 6a: Standard structured cabling carries the signal the full 100m (328 ft), so you're not pulling specialized cable or dealing with signal boosters mid-run. For a warehouse floor, a retail stockroom, or a secure server room to remote workstation scenario, that coverage radius handles almost any single-floor layout without a second extender stage.
• SuperSpeed USB 3.0 at 5 Gbps: The USB3004EXT2 maintains the full SuperSpeed USB 3.0 (5 Gbps) data rate end-to-end. That matters when you're connecting high-throughput devices like USB 3.0 IP camera capture cards, external storage, or USB-attached biometric readers that would bottleneck at USB 2.0 speeds.
• Four USB Type-A ports at the remote unit: The remote receiver terminates in four USB Type-A (9-pin, 5 Gbps) ports, so you can attach a full complement of devices — scanner, camera, token reader, storage — at the remote location without a separate downstream hub. Fewer failure points, fewer power bricks.
• Dual RJ-45 links (local and remote): Both the local and remote units carry two RJ-45 connectors each. The dual-link architecture balances load and maintains USB protocol integrity across the Cat 6a run — critical for maintaining consistent throughput when all four ports are simultaneously active.
• Universal AC power (100–240V, 24V DC output): Both included AC adapters auto-range from 100 to 240V AC input, producing a 24V DC / 1A output at each unit. This makes the system deploy-ready in North American and international facilities without a voltage step-down transformer.
• 8 kV / 15 kV ESD protection: Contact and air discharge ESD protection at those levels matters on long copper runs in industrial environments — loading docks, manufacturing floors, server rooms with significant static buildup. The protection is rated per IEC standards and keeps the extender circuitry from absorbing transients that would damage an unprotected USB controller.
• Aluminum enclosure: The aluminum chassis dissipates heat more effectively than plastic, relevant since both units run continuously in 24/7 deployments. Operating temperature is rated 0°C to 50°C (32°F to 122°F), covering standard indoor commercial and light industrial environments.
• 8 onboard LED indicators: Two each for power, status, link, and USB 2.0/3.0 activity give you immediate visual confirmation of connection health at both ends without opening a management interface. Useful during initial commissioning and for rapid fault isolation when a device stops responding.

Integration and Compatibility

The USB3004EXT2 integrates into any infrastructure where Cat 6a is already deployed — no new cable plant required in most commercial buildings built or upgraded in the last decade. The local unit connects to any host with a USB 3.2 Gen 1 Type-A port (the included cable interfaces via Type-B on the extender side). The remote unit's four USB-A ports are backward compatible with USB 2.0 devices, though throughput for those devices will be limited to USB 2.0 rates. Plan power accordingly: the remote unit's four ports share the 24W total system power envelope, so high-draw devices should be evaluated against that ceiling. For NVR-connected USB storage expansion or remote USB camera attachment in a IP camera deployment, the extender fits cleanly into structured rack and patch-panel environments. Review your PoE switch and cabling infrastructure plans alongside this extender if you're combining USB and IP camera runs in the same conduit paths — Cat 6a serves both, but separate runs are recommended to avoid crosstalk on dense installations. Consult your USB extender selection guide if you're evaluating single-port versus multi-port extender options for your specific device count and distance requirements.

Frequently Asked Questions

Q: What cable type does the USB3004EXT2 require, and does the cable need to be shielded?

A: StarTech specifies Cat 6a or better for the full 100m (328 ft) range. Shielded Cat 6a (STP/SFTP) is recommended in environments with high electrical interference such as manufacturing floors or areas near heavy machinery, as it provides better protection against EMI over long runs.

Q: Can the USB3004EXT2 run without both AC adapters if one end is near a powered host?

A: No. Both the local and remote units require their own AC power source. The system draws 24W total across two adapters, and neither unit is bus-powered from the host USB connection alone. Both included AC adapters must be connected for the extender to operate correctly.

Q: Does the USB3004EXT2 support USB 2.0 devices at the remote end?

A: Yes, the remote unit's four USB Type-A ports are backward compatible with USB 2.0 devices. Those devices will operate at USB 2.0 speeds rather than the full 5 Gbps SuperSpeed rate, which is normal USB protocol behavior.

Q: What is the warranty on the USB3004EXT2?

A: The USB3004EXT2 carries a 2-year manufacturer warranty.

Q: Can two USB3004EXT2 units be daisy-chained to extend beyond 100 meters?

A: The specified maximum range is 100m (328 ft) over a single Cat 6a run. StarTech does not publish specifications for cascading two units, so performance beyond 100m cannot be guaranteed and that configuration is not supported per available evidence.

Q: What operating temperature range does the USB3004EXT2 support?

A: The USB3004EXT2 is rated for operation between 0°C and 50°C (32°F to 122°F), covering standard indoor commercial and light industrial environments. It is not rated for outdoor or sub-freezing installations.

The spec that defines where the USB3004EXT2 fits is simple: 100 meters over Cat 6a at 5 Gbps with four ports at the far end. That combination puts it squarely in the category of infrastructure extenders rather than desktop convenience gear — this is a unit you commission once, rack or surface-mount at both ends, and expect to run continuously. The 24W total system power draw across two universal AC adapters means there are no surprises for facilities teams on either end of the run.

Technical Highlights:

• 5 Gbps end-to-end throughput: SuperSpeed USB 3.0 maintains full 5 Gbps bandwidth across the 100m Cat 6a run — critical when attaching USB 3.0 capture devices or high-speed storage that would saturate a USB 2.0 extender at 480 Mbps.
• 8 kV / 15 kV ESD protection: Contact and air discharge protection at these levels is not standard on basic extenders. On a 100m copper run traversing a warehouse or industrial floor, transient events are a real risk — this spec provides a meaningful safety margin for the connected host controller and attached devices.
• Dual RJ-45 architecture: Both local and remote units carry two RJ-45 ports, supporting the load balancing needed to keep all four downstream USB ports performing consistently rather than competing on a single link.

Deployment Considerations:

• Plan the remote unit's power outlet during site survey — both units need AC power (100–240V input), and the remote location needs a dedicated outlet near the termination point. Forgetting this is the most common commissioning delay on first installs.
• Operating temperature tops out at 50°C (122°F), so avoid installations in unventilated equipment closets in warm climates or near heat-generating equipment where ambient temps can exceed that ceiling during summer months.

The USB3004EXT2 is the right call for a fixed security kiosk, a remote biometric enrollment station, or a distributed surveillance USB hub where structured Cat 6a cabling is already in the walls and you need four full-speed USB 3.0 ports delivered reliably at the far end of a long run — without pulling new specialized cable or managing an IP-based USB virtualization layer.
