UCERB 24 to your system, turn your computer on, and connect the USB cable to a USB

port on your computer or to an external USB hub that is connected to your computer. The USB cable
provides communication to the

When you connect the

UCERB 24 for the first time, a

Found New Hardware

popup balloon (Windows

XP) or dialog (other Windows versions) opens as the

UCERB 24 is detected.

When this balloon or dialog closes, the installation is complete. The

USB LED

should flash and then

remain lit. This indicates that communication is established between the

UCERB 24 and your computer.

If you are running Windows XP and connect the

UCERB 24 to a USB 1.1 port, a balloon displays the

message "

Your USB device can perform faster if you connect to a USB 2.0 port

message. The

UCERB 24 will function properly when connected to a USB 1.1 port.

Caution! Do not disconnect any device from the USB bus while the computer is communicating with

the

UCERB 24, or you may lose data and/or your ability to communicate with the UCERB

24.

If the LED turns off

UCERB 24. To

restore communication, disconnect the USB cable from the computer, and then reconnect it. This should
