The D-Link DUB-H4 2.0 is a Hi-Speed USB 2.0 4-port hub with backward compatibility to USB 1.0 and 1.1. It provides an out-of-the-box industry standard that allows connection of up to four USB peripherals or devices to your USB-ready PC or Mac.
The D-Link DUB-H4 2.0 is designed to provide quick and easy access to the four type A downstream ports for connecting USB peripherals, devices, or other USB hubs. A single type B upstream port connects the DUB-H4 to the host computer, or another USB hub enabling up to 127 devices to be connected by cascading multiple hubs.
As a standard USB hub, the D-Link DUB-H4 buffers USB data from any attached peripheral in compliance with USB specifications to provide an invisible extension of the USB bus. Supporting both low-speed (1.5 Mbps and 12 Mbps) and high-speed (480 Mbps) devices, each port creates a bridge between the peripheral and host computer.
Diagnostic LEDs located on the top of the device provide power state (self-power) and port status on each port. The DUB-H4 2.0 is packaged with all necessary documentation, a six-foot Hi-Speed USB 2.0 AB cable, and an AC power supply to ensure that the user is able to easily and quickly install and use the device.
The D-Link DUB-H4 comes with a one-year warranty.
