• DC Power Connector (J3): The Data Express uses a standard 4-pin DC Power
Connector to accept DC power.
• I/O Connector (J2): The input/output connector provides a standard interface for
all SCSI signals. See Table 2 for J2 pin assignments.
• ID Select Pins (J4): Pins 1-14 are reserved. Pins 15-20 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 1 for J4 pin assignments.
• Enable Termination Power To/From SCSI Bus (W1): The rear panel contains
the bus terminators (active) for 8-bit Single-Ended SCSI interfaces. Jumper is
installed at the factory.
• Onboard Termination (W2): Position "A" is installed at the factory and will disable
termination. Moving the jumper to Position "B" will enable onboard termination.
