The D-Link DSB-H7 is a 7-port Universal Serial Bus
USB hub that allows a user to connect up to seven USB peripherals or devices to their USB
ready PC, iMac, or PowerMac G3. It provides an out of the box industry standard Bus. The
DSB-H7 is targeted at computer users that are expanding the number of USB ports on their
system.
Seamless Connections
The DSB-H7 provides quick and easy access to its seven type 'A' downstream ports
for connecting peripherals with USB support, other USB hubs and devices. A single type
"B" upstream port is provided for connecting to the host computer, or another
USB hub. Configured directly by the operating system, the DSB-H7 operates seamlessly with
both Microsoft's OpenHCI and Intel's UniversalHCI.
Low and High Speeds Supported with Data
Buffering
As a standard USB hub it buffers USB data from any attached peripherals or
devices in compliance with USB Specification version 1.1 to provide an invisible extension
of the USB bus. Supporting both low speed 1.5Mb/s devices and high speed 12 Mb/s devices,
each port creates a bridge between the peripheral and host computer.
Connect High-Powered Devices
Using the DSB-H7's included DC adapter in self-powered mode allows connection of
up to seven high-powered USB devices or up to seven downstream bus-powered USB hubs.
Feature Rich and Easy to Use
Diagnostic LED's are mounted on the top of the device to provide the user with
power state and port status. The DSB-H4 is packaged with all necessary manuals, a 6-foot
USB 'A' to 'B' cable, and a DC power supply to ensure that the user is able to easily and
quickly install and use the device.
