USBExt3c¶

Overview¶

The USBExt3c is a managed two-port USB-C extender and programmable hub designed for enterprise, industrial, and AV environments. It supports:

Local USB links up to 10 Gbps (USB 3.2 Gen 2)

USB 3.2 Gen 1 (5 Gbps) and USB 2.0 extension up to 100 m over Cat 6A cable (HDBaseT-USB3)

Bidirectional PoE++ power extension

Automatic host switching from either end of the extension

When powered over the extension, the USBExt3c provides up to 60 W of total USB-PD output across all USB ports. With local power, up to 90 W shared power is available.

Full software control of the USBExt3c is available using the interactive HubTool App or BrainStem® API via the upstream host connection, Ethernet, or dedicated USB-C Control Port. Acroname’s AnyPort™ technology allows either USB-C hub port (channels 0-1), on either end of the extension, to be dynamically configured as the upstream-facing host port.

Each USB-C port can be independently monitored and controlled, with the ability to:

Monitor, enable, or disable V_BUS on each port

Independently disconnect USB HS and SS for advanced USB testing

Source up to 60 W or sink up to 100 W USB-PD per port

Set current limits and USB charging modes

Automate enumeration delays and port resets

Automate USB port behaviors, set and read PD profiles

The fully bidirectional Power-Over-Ethernet (PoE) subsystem allows a pair of USBExt3c units to operate from a single power source, or to power other PoE-compliant devices (IEEE 802.3bt Class 8), with full software monitoring and control of the power link.

The USBExt3c is managed by the HubTool application, web interface, or BrainStem® API, via Ethernet, RS-232, or USB connections. To start using the USBExt3c, follow the Quick Start Guide.
