== Summary ==
The USB-HUB-3U-ETH is an industrial-grade multifunctional USB hub that adds three USB 2.0/1.1 ports and a 100 Mbit/s Ethernet port via an RJ45 connector. It uses an integrated RTL8152B chip for network connectivity, features a rugged metal case with mounting holes, includes multiple protection circuits, and provides LED indicators for power, network, and USB status.

== Technical overview ==
* Extends the host by adding three USB output ports with a transmission rate of up to 480 Mbit/s (USB 2.0 High Speed).
* An integrated 1-channel RTL8152B Ethernet chip enables 100 Mbit/s network transmission over the RJ45 port.
* Each USB output supplies a maximum of 1.2 A; exceeding this limit triggers short-circuit protection and requires removing the device to reset it.
* Protection circuits include over-voltage, over-current, short-circuit, over-temperature, reverse current, under-voltage lock-out, 8 kV ESD protection, and filtering.
* LED1 through LED3 indicate the enumeration status of each USB port; the red PWR LED signals that power is on.
* The orange network indicator flashes during normal network connection, while the green LINK LED remains steadily lit.
* Operating temperature range is -40 °C to 85 °C without condensation; the module is not waterproof.
* The enclosure is made of industrial metal and includes mounting holes for easy installation in control cabinets or industrial environments.

== Notes and version constraints ==
* No fixed IP address exists – configuration depends on the connected main control unit.
* USB devices must be firmly seated, as a loose connection can prevent enumeration.
* If an LED does not light up, verify that the connected USB device operates correctly and that drivers are installed on the computer.
* The device does not support sharing USB ports over Ethernet; it functions solely as a USB network card.
