Black Box ICU504A USB 3.1 Extender Over CatX — 4-Port

Overview

The Black Box ICU504A is a 4-port USB 3.1 extender that runs over CatX structured cabling, letting you push USB connectivity beyond the 5-meter limit imposed by native USB cable runs. If you're deploying USB-dependent peripherals — industrial cameras, card readers, scanners, or biometric devices — at distances that standard USB simply won't reach, the ICU504A solves the infrastructure gap without pulling dedicated fiber or switching to a different interface standard.

The 4-port configuration means a single CatX home-run can feed up to four USB 3.1 devices at the remote end, reducing the cabling runs you'd otherwise need for multi-device endpoints like kiosk stations, access control clusters, or surveillance equipment bays. That's a real labor and materials savings in any structured installation where conduit fill and patch panel slots matter.

USB 3.1 as the underlying standard supports the bandwidth headroom that high-throughput peripherals demand — frame-grabbers, high-resolution camera feeds, and high-speed card readers all benefit from the headroom versus older USB 2.0 extenders. Leveraging your existing Black Box CatX infrastructure means no new media type to manage and no additional switches or transceivers in the signal path.

For integrators building out USB extender infrastructure in commercial environments, the ICU504A fits cleanly into standard structured cabling plant — terminate to your existing CatX patch panel and you're done. This approach also simplifies troubleshooting: the CatX segment is testable with a standard cable certifier, unlike proprietary extension media.

Key Features

• 4 USB 3.1 ports at the remote end: consolidate multiple peripheral connections onto a single CatX home-run, cutting cable count and conduit fill at multi-device endpoints.
• USB 3.1 standard: delivers the bandwidth headroom that high-speed peripherals require — meaningful for camera feeds and card readers that would saturate a USB 2.0 extender.
• CatX transport: rides your existing structured cabling plant, avoiding additional media converters or fiber runs and keeping the signal path simple and certifiable.
• Black colorway: blends into standard rack and equipment bay environments without requiring additional dress panels.

Frequently Asked Questions

Q: What category of CatX cable does the ICU504A require?

A: The available specifications do not confirm a specific Cat rating requirement. Contact pre-sales engineering to confirm compatibility with your installed cabling plant before ordering.

Q: How many USB devices can be connected at the remote end?

A: The ICU504A provides 4 USB 3.1 ports at the remote endpoint, supporting up to four simultaneous USB peripheral connections over a single CatX run.

Q: Does the ICU504A support USB 2.0 and USB 1.1 devices?

A: USB 3.1 is backward-compatible with USB 2.0 and USB 1.1 devices by standard, though confirmed backward-compatibility for this specific unit is not documented in the available evidence — verify with Black Box before deploying legacy peripherals.

Q: What is the maximum extension distance of the ICU504A?

A: Maximum extension distance is not confirmed in the available specifications. Consult the Black Box datasheet or pre-sales engineering for verified distance limits before designing your cabling layout.

The ICU504A is the unit I reach for when a deployment needs USB 3.1 peripherals at a distance and the site already has CatX home-runs pulled — there's no good reason to add a separate media type when structured cabling can carry the signal. The 4-port remote hub is the key differentiator here: multi-device endpoints like access control clusters or kiosk bays can be served off a single run rather than four.

Technical Highlights:

• 4-Port Remote Hub: one CatX run feeds four USB 3.1 devices at the endpoint — directly reduces cable count and conduit fill in multi-peripheral installations.
• USB 3.1 Bandwidth: the jump from USB 2.0 extenders is material for high-throughput devices like HD cameras or high-speed readers that would saturate older extender hardware.
• CatX Transport: integrates into standard structured cabling plant — the CatX segment is certifiable with standard tools, which simplifies post-installation verification and troubleshooting.

Deployment Considerations:

• Maximum extension distance is not confirmed in the available documentation — nail this down with Black Box before committing to a cabling layout, especially in large floorplate deployments where runs may approach or exceed typical USB extender limits.
• Power sourcing for the remote hub unit is not specified in available evidence — confirm whether the remote end requires local AC power or draws from the CatX run before finalizing your install plan.

Best fit for commercial kiosk clusters, access control multi-reader endpoints, and surveillance equipment bays where CatX is already in the walls and you need to consolidate multiple USB 3.1 devices onto a single structured cabling home-run.
