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.

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 1.5Mbps devices and high speed 12 Mbps* 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-H7 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.

* Maximum transfer rate based on USB 1.1 specifications. Actual data throughput will vary.
