D-Link Hub usb 2.0 7port active dub-h7

The USB DUB-H7 hub allows you to quickly and easily expand a PC or Mac with 7 additional USB ports. Each port complies with the USB 2.0 standard, and therefore has a maximum data transfer speed of 480 Mb/s, which is 40 times greater than the traditional USB 1.1 standard. Hubs have all the advantages of the USB interface: all connected devices are immediately recognized by the hub, without costly and complicated installation. This especially facilitates work with peripheral devices such as scanners or printers, as long as they support the USB 2.0 standard. The times when, in exchange for the convenience of USB installation, you had to accept lower speed are long gone. The DUB-H4 and DUB-H7 hubs can also be used without problems for communication with USB devices with a USB 1 standard interface. Data transfer is regulated so as to adjust the speed also to the requirements of the older USB standard. The hubs have 7 type A downstream communication ports for connecting USB peripheral devices or additional USB hubs, as well as one type B upstream USB port for connecting a computer. Cascading an appropriate number of hubs enables connecting 127 USB devices (scanners, cameras, etc.). The port status can be read at any time on the diagnostic indicators.
