Jumper Setting
==============
x = Jumpers at the shipment
The following jumpers are accessible for the user (use green jumper
plugs, as for J8 use blue jumper plugs):
SCSI ID setting jumper J8
SCSI bus parity jumper J8
Terminator power on/off jumper JP5
Write protected jumper JP4
Motor Auto-start option jumper JP2
Synchronized spindle jumper JP3
Synchronized spindle Terminator JP7
Synchronized spindle signal connector J7 Pins 1-2, 3-4
Note: The DK516C jumpers other than listed above are installed by the
manufacturer (black jumper plugs) and must not be modified or
replaced by the user.

JP5 Terminator Power

|o o| bus (host) (Pins 4-3 OPEN)
+2-1+ x OPEN +5V source for terminator is supplied only from the
drive controller. (Pins 4-3 CLOSED)
Note: Terminator power source is supplied to the terminator resistor
module from the host that pulls up the SCSI interface signals in the
controller so that the SCSI bus lines will not be pulled down when
DK516C power is turned down.
JP4 Write Protected
--------------------
CLOSED Write protected. The disk can be only read and cannot be
written.
x OPEN Read or write. The disk is enabled for both read and
write.
JP2 15-16 Motor Auto-start option
----------------------------------
x 15-16 CLOSED The spindle motor is started automatically when power
is turned on.
OPEN The Spindle motor is not started automatically when
power is turned on. It can be started by using SCSI
command to start the drive.

Whenever you change the orientation of the drive it is recommended to
reformat the disks.
Mounting
--------
In order to prove the shock protection ability, design the cabinet of
a system as described in below.
- Fix the drive with four screws by using the proper 4 screw holes
(total of 8 holes) of the drive.
- The insertion depth of the mounting screws below the drive surfaces
must be less than
3.5mm (0.14inch) for side holes
5 mm (0.2 inch) for bottom holes
Sequential Activation of Motors
-------------------------------
When multiple disk drives are connected and turned on simultaneously,
a large amount of current will flow. It is recommended to turn the
motors on one by one at an interval of approx. 35 seconds. Indication
of "READY" on the last drive reports that all drives have been
activated.
