DUB-104

4-Port USB 2.0 Pocket Hub

Power Adapter (5V 2.5A) Using a power supply

with a different voltage rating

will damage and void the

warranty for this product.

Installing the DUB-104

A. Plug the AC adapter into the

DUB-104 and into a power

socket in a power-strip or a

wall jack. (optional)

C. Your computer will automatically

detect and install the DUB-104.

You may now connect USB 2.0

or USB 1.1 devices to an

available USB port on the front of

the DUB-104.

B. Plug the USB type A dongle

(found on the bottom of the

DUB-104) into an available

USB 2.0 port on your computer

(or a USB 1.1 port if you don’t

have USB 2.0).

LED indicator

• The Power LED indicator is blue and lights up when the DUB-H4 is powered on by

using the external power adapter or by running on power supplied from the

computer (bus powered).

• If a port becomes overloaded, a “current exceeded” event will take place. The LED

will go off and the message “USB HUB Current Limit Exceeded” appears on the

monitor. Reset the DUB-104 by disconnecting the power adapter (if used) or

disconnecting the dongle from the PC for 5 seconds and then powering it back on

by connecting the AC power adapter or reconnecting the dongle to the PC.

Tips

• When connecting USB cables between USB devices and the DUB-104, make sure

that the cables are connected securely.

• Remember that when connecting USB 1.1 devices to a USB 2.0 hub or host

adapter, the USB 1.1 device will not work at USB 2.0 speeds.

• The DUB-104 does not have an on/off switch. It is always on once the external

power adapter has been plugged into a power source or the dongle has been

connected to a PC’s USB port.

• Connecting USB 1.1 devices to the DUB-104 may cause all USB devices

connected to the hub to work at USB 1.1 speed. To ensure 480Mbps throughput for

your USB 2.0 devices, don’t connect USB 1.1 and USB 2.0 devices to the hub at

the same time.

• D-Link recommends that while using a USB device that includes an AC power

adapter, that you use the power adapter to ensure proper power and current supply

to that device.

• Please remember to unplug devices properly to ensure that no data loss or

corruption takes place with your operating system.
