￿¡ Connecting the SCSI cable

Caution: ￿E Connect the cable before turning the power on.

￿E The use of interface cables other than shielded cables or specified equivalents will invali- date the certification of this scanner and may cause interference levels which exceed the limits established for this equipment.

￿E 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 be capped with a terminator.

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 *1 to the SCSI connector on the rear of the scan- ner.

3.If the other connecter is not used, cap it with the attached terminator *2.

*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.
