This standard defines mechanical, electrical, timing requirements, command, and task management delivery protocol requirements to transfer commands and data between SCSI devices attached to a SCSI parallel interface. This standard is intended to be used in conjunction with the SCSI command sets. The resulting interface facilitates the interconnection of computers and intelligent peripherals and thus provides a common interface standard for both system integrators and suppliers of intelligent peripherals.
