• I/O Connector (J2): The input/output connector provides a standard interface for
all SCSI signals.
• DC Power Connector (J3): The DE100 uses a standard 4-pin DC Power Connector
to accept DC power.
• 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 2 for J4 pin assignments.
• Enable Termination Power To/From SCSI BUS (W1): This 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.
