Connecting the Scanner to Your Computer
You can connect the scanner to your computer in any of these ways:
■USBIf you have a Power Macintosh® with built-in USB support or your computer is running Windows 2000 or Windows 98 (factory installed), you can connect the Expression 1640XL with the USB cable that came with the scanner. Windows 2000 or Windows 98 must be preinstalled on your computer; they cannot be upgraded from an earlier version of Windows. There is no USB support for Windows 95 and Windows NT 4.0.
■SCSIIf you have a Power Macintosh with built-in SCSI support or a compatible PCI SCSI/SCSI 2 adapter board, or your Windows computer has an ASPI-compliant SCSI 2 board (Adaptec® boards are recommended), you can connect the scanner with a SCSI 2 cable not more than 19.7 feet long. If you’re connecting multiple SCSI devices, the total length of the SCSI bus (cables) should not exceed 9.8 feet. If your computer is running Windows 95 or Windows NT 4.0, you must use a SCSI connection.
■IEEE 1394 (FireWire)If you have purchased the optional IEEE 1394 FireWire scanner interface card, you can connect the scanner to your Power Macintosh or PC with the IEEE 1394 FireWire cable. Your Power Macintosh must have a built-in IEEE 1394 FireWire port or an IEEE 1394 FireWire PCI card, and must be running Macintosh
OS 8.6 or later with FireWire Update 2.1 or later. Your PC must have an OHCI compliant FireWire port or card, and must be running a pre-installed version of Windows 2000.
Adaptec Power Domain® 2940UW and 2940U2W SCSI boards for the Macintosh are designed for hard drives only and are not compatible with scanners.
If you install a USB card in your Macintosh and then upgrade your system to OS 8.6, your USB Manager won’t be installed and your scanner may not work. To have USB support, you must perform a full installation of OS 8.6 from a CD-ROM before you install the card.
