3.2. Legacy SCSI Cabling
SCSI cabling is a parallel wiring plant analogous to common personal computer parallel printer cabling. In the SCSI cable, each bit of a data byte is given its own wire. A SCSI cable may have 8 (narrow SCSI) or 16 (wide SCSI) data lines, plus control lines to manage device selection and data transmission. The effective transmission rate is governed by the number of data lines provided and the clock rate at which bytes of data are sent concurrently. Although new parallel SCSI designs such as high-voltage differential and low-voltage differential (LVD) have enabled higher throughput, the overall distance limitation of SCSI cabling is 25 m, and device support is limited to 15 devices on a SCSI chain.
In a parallel SCSI configuration, ...
