Jumpers

HITACHI DK511 PRODUCT MANUAL K6600061 REV. 7, 10/01/1985

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

Adjustment
----------
There are two types of jumper switches for DK511 as follows:

 CAUTION
 1. Jumper Switches with GREEN connectors: to be used for an assign-
    ment of unit address and for selection of optional functions, and
    to be arranged when installing the unit or replacing the PC board.

 2. Jumper Switches with BLACK connectors; to be used for adjusting
    servo control circuits. These need not be readjusted when
    installing the unit or replacing to a spare PC board since they
    have already been adjusted at shipment. Even if a readjustment is
    needed by all means, be sure to make a record of their preset
    status prior to readjust them for the capability of recovery.

Setting of GREEN Jumper Switches
--------------------------------

JP68 Drive Select Jumper Switch

When shipped, this jumper is set in the primary position.

Terminator
----------
If the multiple drives are connected in the daisy chain mode, only
the last drive must be terminated with a terminator module. When
shipped, the terminator module (IC#IC) is installed. Remove it all
but the last drive (if the multiple drives in the daisy chain mode).

Adjustment Specification (BLACK Jumper)

NOTE
Since adjustment portions are already adjusted when the device is
shipped, don't move them unless understanding the prior "CAUTION"
of this chapter.

JP4A Head Sel #7 Fault Jumper Switch
------------------------------------
(This jumper is available from SZ073 Rev. 7)

Write Fault caused by invalid head selection is ignored by this
option. If this option doesn't use, the selection of HD#7 causes
Write Fault. This option is available on and after SZ073 REV. 7.

   Primary                 Optional
   -------                 --------

   3|X| Fault.               3|o|
    +-+                       +-+

When shipped, this jumper is set in the primary position.

 PLO free-running frequency
 --------------------------
 - Pull J6 Connector and insert Jumper socket in JP164 for allowing
   the error signal to set at zero.

 - Turn the power on, and adjust the value of JP117-6 pin within the
   range of 10 MHz   1% using JP123.

 - After completion of aforementioned adjustment, turn the power off,
   insert J6 Connector in the original position, and then pull Jumper
   Socket out of JP164.

 - Turn the power on again and ensure that an operation is in normal
   status (device in READY status).
