Using a SCSI Connection 11
Follow these steps to connect the scanner to a SCSI interface:
1. Make sure the scanner and computer are turned off. (The scanner is off when the
P
OPERATE button is out and the ERROR and READY lights are off.)
2. Squeeze the lock releases on the lock
connector end of the 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 the computer, or to
another SCSI device in the chain. Tighten the screws to secure the cable.
4. Locate the SCSI terminator switch at the rear of the scanner.
If the scanner is the only SCSI device, or if it’s the last device in a SCSI chain,
leave the terminator switch turned ON.
If you’ve connected the scanner in the
middle of a SCSI chain, turn the
terminator switch OFF.
5. Plug in the power cables for the computer,
scanner, and other external SCSI devices.
Do not connect the scanner to the computer while either is turned on,
or the scanner could be damaged.
Don’t use an external terminator.
