¡ Connecting the SCSI cable
Caution:
This scanner connects to your host computer
through the SCSI (Small ComputerSystem In-
terface). Connect the cable as follows.
1. Make sure that the power of all devices on
the SCSI chain are turned off.
2. Connect a high-density 50-pin type SCSI
2 cable which complies with ANSI
the SCSI connector on the rear of the scan-
ner.
3. If the other connecter is not used, cap it with
the attached terminator
*1 Note about SCSI cables
There are several types of SCSI connectors, such as the high density 50-pin connector, the D-sub
25-pin connector, and the 50-pin flat connector. You have to use a SCSI cable that matches the
connectors on your adjacent devices or host computer. This scanner has two high density 50-pin
connectors. The SCSI cable packed with your scanner has a high density 50-pin connector at each
end. If your computer (or any other connected device) has such connectors, you can use the at-
tached cable. However, if you want to connect this scanner with a computer or device that has a
different type of connector, you have to get a cable or a connector adjuster that fits the device or
computer, as well as the scanner. In that case, you must use a SCSI cable that complies with ANSI.
*2 Note about terminators
Generally, you need two terminators at each end of a SCSI chain. If you connect this scanner at the
end of a SCSI chain, you have to cap the scanner's unused SCSI connector with the attached
terminator. If you connect this scanner in the middle of a SCSI chain that is already terminated, you
do not need the attached terminator.

Connect the cable before turning the power on.
E
The use of interface cables other than shielded cables or specified equivalents will invali-
E
date the certification of this scanner and may cause interference levels which exceed the
limits established for this equipment.
The total length of the SCSI bus should be no more than 6 m.
E
Either one of the two SCSI connectors can be used, but an unused SCSI connector must
E
be capped with a terminator.
