Do not connect the scanner to the computer while it is turned
on, or the scanner could be damaged.
2. Squeeze the lock releases on the lock
connector end of your SCSI cable, and
then plug the cable into either SCSI
connector on the back of the scanner.
The cable is secure when both connector
locks snap in.
3. Connect the pin end of the SCSI cable
to the SCSI port on your computer, or to another SCSI device in the chain.
Tighten the screws to secure the cable.
If you're connecting multiple SCSI devices, the total length
of the SCSI bus (cables) should not exceed 9.8 feet (three
meters); otherwise the system may not work properly. If you
are connecting the scanner directly to your computer, use a
cable no more than 19.7 feet (six meters) long.
Don't use an external terminator.
4. Locate the SCSI terminator switch at the rear of the scanner.
If the scanner is your only SCSI device, or if it's the last device in a SCSI chain,
leave the terminator switch turned
If you've connected your scanner in the
middle of a SCSI chain, turn the
terminator switch
5. Plug in the power cables for your
computer, scanner, and other external
SCSI devices.
