General Product Definition; Scsi Interface - Seagate ST251N Product Manual

2.0 GENERAL PRODUCT DEFINITION
The ST251N/277N feature an integral SCSI-compatible controller. This
embedded controller performs all of the functions that were previously
implemented by an add-on, controller. And, with the controller
on board, the diagnostic capabilities of the drive are enhanced because
the controller is able to optimize drive performance and error recovery.
Our low-cost ST01 Host Adaptor provides the SCSI interface between
your IBM PC/XT/AT (or compatible) and up to seven SCSI devices.
Refer to the Seagate ST01 Host Adaptor Product Manual for detailed
product definition and specifications.
2.1 SCSI INTERFACE
The embedded controller supports the SCSI interface as defined in
the ANSI X3T9.2/82-2 document. The interface hardware is capable of
transferring up to 12 megabits/second using asynchronous data trans-
fer. Devices on the SCSI interface are daisy-chained together using a
common cable. Both ends of the cable are terminated. All signals on
the interface are common between all devices.
Refer to the Seagate SCSI Interface Manual for a detailed discussion
of the SCSI interface.
