Connecting to the Computer
Connect the scanner to your computer using the supplied USB interface cable. The USB interface allows
three basic configurations. The scanner can be connected directly to the USB connector on the
computer, directly to a USB hub that is connected to the computer, or to a throughput USB connector on
another device that supports the USB interface. The two configurations are shown below.
Configuration 1
Scanner Directly Connected to
Computer
Configuration 2
Scanner Directly Connected
to HUB
Other USB Device
Self-Powered USB Hub
USB port expansion device (self-powered hubs
can power other USB devices)
Use a USB hub when there are no
free USB ports on your computer for
connecting the scanner and other
USB devices. Use a self-powered USB
hub with a 500-milliampere (mA) bus
power supply.
