DSB-H4SMK

The D-Link DSB-H4SMK is a 4-port Universal Serial Bus USB hub with 2 additional PS/2 ports for connection of a keyboard and mouse, and 1 RS-232 serial port for connection of a serial device. It allows a user to connect up to four USB peripherals or devices, a PS/2 keyboard, a PS/2 mouse, and a serial device to a Windows98 PC. The DSB-H4SMK is targeted at Windows98 PC laptop and desktop users that are expanding the number of USB ports on their systems and need to connect a serial device, PS/2 keyboard and PS/2 mouse.

The DSB-H4SMK provides quick and easy access to the four type 'A' downstream ports for connecting peripherals with USB support. It also allows other USB hubs and devices to be connected. A single type "B" upstream port is provided for connecting to the host computer, or another USB hub. Two PS/2 ports are provided for easy connection of a keyboard and mouse. A single serial port provides connection of a serial device.

As a standard compliant USB hub, the D-Link DSB-H4SMK buffers USB data from any attached peripherals or devices in strict adherence 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. The two PS/2 ports allow a user to attach a legacy mouse and keyboard.

In self-powered mode, the DSB-H4SMK can support up to four high-powered USB devices or up to four downstream bus-powered USB hubs. Diagnostic LED's are mounted on the top of the device to provide the user with power and port status. The DSB-H4SMK is packaged with all necessary manuals, a 6-foot USB 'A' to 'B' cable, a driver diskette, and a DC power supply.
