SCSI-2 Connector
The PDR200 provides a number of SCSI-2 68-pin interface connectors at the rear
panel, including the one on the SCSI board which is reserved for the PLS200 Library
System.
For a 2-channel Profile, SCSI interfaces are identified as:
SCSI A - Master EDR board rear panel connector
SCSI B - Rear Panel connector
For a 4-channel Profile, SCSI interfaces are identified as:
SCSI A - Master EDR board rear panel connector
SCSI B - Rear Panel connector
SCSI C - Slave EDR board rear panel connector
SCSI D - Rear Panel connector
All SCSI-2 connectors have the same pin-outs. This includes an internal SCSI-2
interface that is used with the disk drives that are resident within the PDR 200. Figure
A-3 shows a SCSI connector and Table A-5 lists the pin-outs.
Note that in Table A-5, signals preceded by a dash (-) indicate signals that are true,
asserted, and active when low.
