This section summarizes pinouts for these connectors:

• single-ended high-density SCSI (68-pin)

• single-ended high-density SCSI (50-pin)

• differential high-density SCSI (68-pin)

Single-Ended High-Density SCSI Pinouts (68-Pin)

Figure A-1 shows the 68-pin connector.

In Table A-6, the hyphen preceding a signal name indicates that the signal is active-low.

Eight-bit devices that connect to the P cable leave these signals open: -DB(8), -DB(9),

-DB(10), -DB(11), +DB(12), +DB(13), +DB(14), +DB(15), +DB(P1).

All other signals are connected as shown in Table A-6.
