Notes.
[1] See
SCSI Interface Product Manual
(part number 77738479), Section 4.5
[2] Maximum SCSI asynchronous interface transfer rate is given in Section 4.2.3 of this manual.
[3] Synchronous Transfer Period is determined by negotiations between an Initiator and a Drive. The Drive is
capable of setting periods as given in Section 9.5. See also Sections 3.1.5.2 and 3.5.3.2 of the
SCSI Inter-
face Product Manual for a description of synchronous data transfer operation.
General timing diagrams for SCSI interface operation are shown in the SCSI Interface Product Manual , Section
4.5. The specific timing values that apply to this drive are listed in Table 18.
