The DIGITUS DA-70231 is a USB 3.0 4-Port Hub that expands the connection options on a PC or Mac by up to four additional USB interfaces. The device enables simultaneous use of multiple USB devices and supports the Super-Speed USB 3.0 specification with a maximum data transfer rate of 5 Gbps. It is backward compatible with USB 2.0 and USB 1.1, allowing older devices to be connected without issues. The connection is made via a USB-A plug on the host system, while the hub is powered through a separate power supply.

Applications
This hub is suitable for use in office environments, home settings, and small IT infrastructures where multiple USB devices such as external hard drives, printers, keyboards, or mice need to be connected simultaneously. Support for Plug & Play and Hot-plug allows devices to be connected and disconnected without restarting the system. Compatibility with operating systems such as Windows 7, 8, Vista, XP, and Mac OS 10.x makes the hub universally applicable.

Functions and Features in Detail
The DIGITUS DA-70231 features four USB-A sockets (A/F) as outputs and one USB-A plug (A/M) as input. Power supply is provided by an external power adapter with an output voltage of 5 V and a current of 3.5 A, included in the delivery. Additionally, a USB connection cable with a length of 1.2 meters (type AM-AM) is provided. The devices are equipped with overvoltage protection on all outputs to safeguard connected peripheral devices from voltage spikes.

Technology Explained Simply
The USB 3.0 technology enables significantly higher data transfer rates compared to USB 2.0, which is particularly beneficial when transferring large data volumes, such as with external hard drives or USB webcams. The Super-Speed function (5 Gbps) is supported by the use of a separate power adapter, which provides sufficient power for all connected devices. The Plug & Play feature means no additional driver installation is required — the device is automatically recognized and configured by the operating system.

Compatibility and Accessories
The hub is compatible with the USB 3.0 specification and operates backward compatible with USB 2.0 and USB 1.1. The connectors are standardized (USB-A sockets and plugs), so no special adapters are required. The included cable (AM-AM, 1.2 m) allows flexible placement of the hub in the workspace. The use of an external power supply ensures stable power delivery, even when multiple power-hungry devices are connected.

Installation and Mounting
Installation is done by simply connecting the USB cable between the host system and the hub. The external power adapter is plugged into a power outlet, activating the hub. Devices can be connected directly to the USB-A sockets after the hub is connected. The Hot-plug function allows devices to be connected and disconnected during operation without restarting the system.

Operational Advantages
The DIGITUS DA-70231 offers a reliable and powerful extension of USB connections. The external power supply prevents power shortages when multiple devices are connected. The combination of USB 3.0, Plug & Play, and Hot-plug ensures user-friendly and low-maintenance operation. The design with black top and bottom surfaces in piano finish and an aluminium-coloured edge fits visually into modern work environments.

The product is classified as a small IT and telecommunications device (Category 6 under ElektroG) and is subject to the WEEE Directive.
