2. Setting up the Scanner

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.
