IEEE 1394 AND USB INTERFACES
IEEE 1394 AND USB
The IEEE 1394 or FireWire interface and the USB interface allow data to be transferred between a
computer and devices like scanners, printers, and digital cameras.The advantages to these inter-
faces are:
• Faster data transfer rates (100Mbps or more with IEEE 1394, 12Mbps with USB1.1)
• No allocation of an ID number or the selection of a terminator is necessary
• Connection and removal of the device from the computer while on
• Automatic confirmation of the connected device from the computer
CAUTION
• Never connect or disconnect the IEEE 1394 or USB cable while the computer, DiMAGE Scan
Elite II, or other devices are operating or transferring data.
• Do not connect or disconnect the cable while the computer is starting up or shutting down.The
computer or scanner may not operate properly.
• The scanner should be connected directly to the computer’s IEEE 1394 or USB port. Attaching
the computer to an IEEE or USB hub may prevent the scanner from operating properly.
• An interval of at least five seconds is required between disconnecting and connecting the scan-
ner.
• When using an IEEE 1394 or USB storage device, it is not recommended to save scanned data
directly to the device. Save the data on the computer’s hard disk before transferring the data to
the storage device.
• The unused port should always be covered with its protective cap.When the scanner is not in
use for extended periods, unplug the cable and reinsert the port cap.
DISCONNECTING WITH THE COMPUTER AND SCANNER ON
WHEN USING THE USB CABLE, OR WHEN USING THE IEEE
1394 CABLE WITH WINDOWS 2000/XP
1 Quit the utility software.
2 Confirm the DiMAGE Scan Elite II indicator lamp is on and not blink-
ing.
3 Disconnect the IEEE 1394 or USB cable.
