Notes.
[1] See the SCSI Interface Product Manual , P/N 77738479 (Volume 2), 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, P/N 77738479, for a description of synchronous data transfer operation.
