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.
