The external 68-pin SCSI connector on the rear of the Origin Vault chassis for the 3.5-inch drives supports both Ultra SCSI and SCSI-2 devices. It sends single-ended SCSI signals or differential signals, depending on the Origin Vault version. The external 68-pin SCSI connector for the 5.25-inch drives supports SCSI-2 devices only and sends single-ended signals only.
Table A-6 lists pinouts for the single-ended connection. In this table, the hyphen preceding a signal name indicates that the signal is low.

Table A-7 lists pinouts for the differential connection. In this table, the hyphen preceding a signal name indicates that the signal is low.
