Chapter 3 The SCSI Interface
The SCSI Interface
The computer interface used exclusively with Coolscan is called a Small
Computer System Interface (SCSI - pronounced ‘scuzzy’). This interface has been
adopted as a standard in the PC computing environment and is utilized by many com­
puter devices, including disk drives, scanners, printers and CD-ROM drives.
System Requirements
for SCSI Installation
In order to connect a SCSI device to a PC or compatible, the following require­
ments must be met:
1. The computer system must have a SCSI controller card (A Nikon-tested card has
been provided with Coolscan).
2. The SCSI device must be set to an unu.sed SCSI ID number.
3. A proper SCSI cable must connect the SCSI controller to the SCSI device.
4. The SCSI bus cabling must be correct if more than one device shares the bus.
5. The SCSI bus must be properly terminated.
6. Appropriate SCSI driver software must be used.
These requirements will be addressed in the following sections.
Setting the SCSI ID
The SCSI bus is a sort of‘data highway,’ with the SCSI devices connected to the
SCSI bus representing ‘stops’ on this highway. Each device requires its own distinct
SCSI ID number so that the PC can easily locate it through the SCSI controller card.
Because the SCSI bus can accommodate up to eight devices, internal or external, a SCSI
ID number can have a value between 0 and 7. There are no implicit regulations regard­
ing the allocation of these numbers. Typically, however, the PC’s SCSI controller card
would be assigned SCSI ID number 7, while the SCSI devices would utilize numbers 0
through 6.
The SCSI ID number is commonly set by a switch on the rear of the SCSI device.
