Understanding SCSI

Connector Types

Several different types of SCSI connectors are used on SCSI devices,

and each type requires a different kind of cable. The following three

diagrams illustrate the different kinds of SCSI connectors:

The total length of cabling on the SCSI bus should not exceed the

maximum lengths listed in the following table:

Maximum Cable Lengths

Max Devices Supported

Data Transfer Rate

Max Cable Length

7Fast SCSI

(10 MBytes/sec)

3 m (9.8 ft.)

75 MBytes/sec

(Asynchronous or Synchro-

nous)

6 m (19.7 ft.)

SCSI-2 High-density 50-pin Connector

Typically used with high-performance CD-ROM drives, hard disk drives, Jaz drives,

and Plug and Play devices.

SCSI-1, Low-density Centronics 50-pin Connector

Used with many CD-ROM drives, hard disk drives, SCSI tape drives, and scanners.
