Connecting to the Host Computer

This scanner connects to a host personal com- puter through a SCSI interface. This section provides an overview of SCSI, and explains how to connect the scanner to a host com- puter.

What is SCSI?

“SCSI” (Small Computer System Interface) is an interface standard that is used for high- speed data transfer between a peripheral device and a host computer.

∙In a SCSI connection, ANSI-compliant SCSI cables are used to connect one or more peripheral devices in daisy chain fashion to the host computer.

∙Each device is assigned a unique SCSI ID (0 to 7), which must be set for the device before turning on the power and before turning on the computer.

∙The last device in the daisy chain requires a terminator.

1:SCSI cables

2:Up to 7 devices

3:Terminator

Important

❒If two or more devices in a daisy chain share the same SCSI ID, misoperation and data loss may result. Set a unique SCSI ID for this scanner that does not duplicate the SCSI ID of any other de- vice.

SCSI Connection Require-

ments for the Scanner

∙This scanner complies with the SCSI-2 standard. SCSI-1-compliant peripheral devices can also be connected and used with this scanner. The SCSI interface on the scanner has a 50-pin half-pitch (pin type) connector. Connect an ANSI- compliant shielded SCSI-2 cable to the scanner. Note that some combinations of cables and SCSI boards will not work together properly, so check this carefully.

∙If you are using a SCSI board and driver software that supports SCAM, the SCSI ID of this scanner will be set automati- cally, so there is no need to set the ID. If you are using a driver that does not have a SCAM function, it will be necessary to set the SCSI ID for the scanner if the SCSI ID is identical to that of another device that is connected.

∙The scanner’s terminator can be enabled or disabled by turning a DIP switch on or off.
