HITACHI  DK324C-21A  JUMPER SETTING K2500468 18/7/91

 Jumper Setting
 ==============

 The following jumpers are accessible to the user

   SCSI ID setting jumper           J6  Pin 1 6

   SCSI bus parity jumper           JP2 Pin 3 4

   Terminator power on/off          JP3 Pin 1 4

   MOTOR START/STOP setting jumper  JP2 Pin 1 2

 NOTE
 The DK324C jumpers other than listed above are installed by the
 manufacturer and must not be removed or replaced by the user.

 Never remove any of the "BLACK" factory set jumpers. These jumpers
 are unique to each drives. All jumpers should be set with power off.

 NOTE
 By using an extension cable from J6 connector, SCSI ID setting and
 LED are externally available.

 NOTE
 The terminator (TM114) of the DK324C other than the last drive of
 SCSI Daisy Chain MUST be removed.


 J6 SCSI ID setting jumper

   +----------+-----------------------+
   | SCSI ID  | 2(2)    2(1)    2(0)  |

 JP2 SCSI bus parity setting jumper
 ----------------------------------
 JP2 3-4 CLOSED  Disables SCSI bus parity
                 (DEFAULT)
     3-4 OPEN    Enables SCSI bus parity


 JP3 Terminator power
 --------------------
   +-----+
  4|xxxxx|3  +5Volt source for terminator is supplied only from the
  2| o o |1  SCSI bus
   +-----+

   +-----+
  4| o o |3  +5Volt source for terminator is supplied only from the
  2|xxxxx|1  drive controller.
   +-----+   (DEFAULT)

 NOTE
 Terminator power source is supplied to the terminator resistor module
 from the host that pulls up the SCSI interface signals in the drive
 controller so that the SCSI bus lines will not be pulled down when
 DK324C power is turned down.


 JP2 MOTOR START/STOP Option jumper
 ----------------------------------
 Pins 3 4 CLOSED  The MOTOR START/SOP Option is not selected.
                  The spindle motor is started when the DK324C
                  power is turned on.
                  NOTE
                  When MOTOR START/STOP option is not used, the
                  controller does not respond to the host for
                  about 20 sec from Power turn-on to Drive Ready.

 Pins 3 4 OPEN    The MOTOR START/STOP option is selected. The
                  spindle motor can be started or stopped by using
                  SCSI command.

 When the MOTOR START/STOP option is selected, the drive enters the
 motor stop state when its power is turned on.
 Use the Start/Stop Unit (1B) command to start or stop the drive.
