SlimSCSI 1480 User’s Guide

Understanding SCSI

SCSI (pronounced “scuzzy”) stands for Small Computer Systems 
I

nterface. SCSI is an industry standard computer interface for con-

necting SCSI devices (such as hard disk drives, CD-ROM drives, and 
scanners) to a common SCSI bus.

SCSI bus is an electrical pathway consisting of a SCSI adapter 
(such as the SlimSCSI adapter) installed in a computer and one or 
more SCSI devices. SCSI cables are used to connect the devices to the 
SCSI card.

For the SCSI bus to function properly, SCSI IDs must be assigned to 
the SCSI devices and the SCSI adapter, and the SCSI bus must be 
properly terminated.

SCSI IDs

Each device attached to the SlimSCSI 1480 adapter, as well as the 
adapter itself, must be assigned a unique SCSI ID number from 0 to 
6. A SCSI ID uniquely identifies each SCSI device on the SCSI bus 
and determines priority when two or more devices are trying to use 
the SCSI bus at the same time.

The SlimSCSI 1480 adapter is preset to SCSI ID 7, which gives 
it the highest priority on the SCSI bus.

In Windows 95, you can use the Device Manager to view the 
SCSI ID and other information about each installed SCSI 
device.

If you installed Adaptec

®

 EZ-SCSI

®

 software, you can use the 

SCSI Explorer utility to view the SCSI ID and other informa-
tion about each installed SCSI device.

SCAM Protocol

The SlimSCSI 1480 supports the SCSI Configured AutoMatically 
(SCAM) protocol, which assigns SCSI IDs dynamically and resolves 
SCSI ID conflicts automatically when you start the computer. If you 
have SCSI disk drives or other SCSI devices that support SCAM, 
you do not need to manually assign SCSI IDs to these devices.
