• I/O Connectors (J3, J4, & J5) - These connectors provide a standard interface for all
SCSI signals (Figure 5). See Table 2 for pin assignments.
• DC Power Connector (J6) - A standard 4-pin DC power connector is used to accept
DC power.
• ID Select Connectors (J3A, J3B & J3C) - Pins 1-8 of these connectors provide unit
SCSI ID selection for the computer system or expansion chassis. For remote ID selection
through an expansion chassis, an appropriate cable must be attached to these pins and
the unit ID must be set to "0". The unit ID can be set with a rotating switch located inside
the receiving frame (Figure 10).
• Disable Termination (DT) - A factory installed jumper on these pins disables
termination. Removing this jumper will enable termination. Remove this jumper if the drive
is physically located at the end of a SCSI daisy chain.
• Remote Activity LED (RLED) - These pins provide power for a remote LED device
activity indicator (Pin 11=Cathode, Pin 12=Anode).
• Enable Termination Power To/From SCSI Bus (TPWR) - This jumper is installed at
the factory.
