Section 7
INTERFACES
7.1 OVERVIEW
This section describes the interfaces used by the MD21 Controller.
It includes information about how the MD21 implements the SCSI bus
interface electrical and mechanical requirements, and how it
implements the ESDI interface electrical requirements. It also
describes the user panel connection and the DC power connection.
This section is divided into five subsections, as listed in the
following table:
Subsection Title
7.1 Overview
7.2 SCSI Bus Interface
7.3
ESDI Disk Drive Interface
7.4 User Panel Connection
7.5 DC Power Connection
7.2 SCSI BUS INTERFACE
This subsection provides information about MD21 Controller
implementation of SCSI bus electrical and mechanical requirements.
7.2.1 SCSI BUS INTERFACE PHYSICAL DESCRIPTION
The following features of the SCSI Bus Interface should be noted:
• SCSI bus devices are daisy-chained with a common cable; both
ends of the cable are terminated.
• All signals are common among all SCSI bus devices.
• The MD21 Controller supports the ANSI SCSI specification
single-ended option for drivers and receivers.
