• I/O Connector (J2): The input/output connector provides a standard interface
for all SCSI signals. See Table 4 for J2 pin assignments.
• DC Power Connector (J3): The Data Express uses a standard 4-pin Molex
Power Connector to accept DC power.
• ID Select Pins (J4): Pins 1 through 12 are reserved. Pins 13 through 20 of this
connector provide unit SCSI ID selection for the computer system or expansion
chassis. For remote ID selection through an expansion chassis, the unit ID must
be set to '0' or open (no jumpers installed) on these pins. See Table 2 for J4 pin
assignments.
• Enable Termination Power To/From SCSI BUS (W1): This jumper is installed at
the factory.
