• I/O Connector (J2): The input/output connector provides a standard interface for
all SCSI signals. See Table 2 for J2 pin assignments.
• DC Power Connector (J3): The Data Express uses a standard 4-pin DC power
connector to accept DC power.
• ID Select Pins (J4): Pins 1-12 are reserved. Pins 13 -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): This jumper is installed
at the factory.
• Onboard (Receiving Frame) Termination (W2): Position "A" is installed at the
factory and will disable termination. Moving the jumper to position "B" will enable
termination.
