2.4 SCSI-2 and SCSI-3 Cabling Differences

2.4.2 SCSI-3 Cabling

SCSI-3 devices are daisy-chained using a common 68-conductor P-cable and, optionally, a 68-conductor Q-cable. Both ends of each cable are terminated. The primary SCSI-3 bus carries a 16-bit data bus and control signals. A primary SCSI-3 bus P-cable provides therefore a 16-bit data path. A secondary SCSI-3 bus Q-cable carries an additional 16-bit bus that, used in conjunction with a primary SCSI-3 bus, provides a 32-bit data path.

The BI0316 supports the P-cable option of the SCSI-3 standard.
