SCSI Cables
The cable you use to attach the scanner to your computer must not
exceed 9.8 feet (3 meters).
If you are connecting multiple SCSI devices to your computer, you
may need to purchase several SCSI cables before setting up your
SCSI chain. Be sure the SCSI cable connectors are suitable for your
hardware, depending on the maker of your SCSI device and SCSI
interface board.
To connect the scanner to another SCSI device, the length of cable must
not exceed 19.7 feet (6 meters); otherwise the system may not work
properly.
SCSI ID
Each device has a SCSI ID
number: the SCSI adapter in the
computer is usually number 7,
and each of the other devices
must have a different number
between 0 and 6. The EPSON
Expression 800 default SCSI ID
number is 2.
You’ll find the SCSI ID rotary
switch at the rear of the
scanner.
