     ON      ON      ON      ON          15

Keys 1 to 4 are used for setting the disk logical address (0 - 15).
Switch positions are binary coded.

    Key 5
        -----
    ON  Enable
    OFF Disable

This drive supports the tag 4/5 functions. The user can select these
functions by setting Key 5. In the OFF position tag 4/5 are
disabled. Control units that do not support teg 4/5 require this set
to OFF.

    Key 6
    -----
    ON  Soft sector mode
    OFF Hard sector mode

The user can select either hard sector or soft sector mode

    Key 7
    -----
    ON  Tag 2 system (ANSI type 1 mode)
    OFF Tag 4 system (ANSI type 2 mode)

Tag 2 and Tag 4 systems have different methods of sending the most
significant bits (2 bits). Select the system used with Key 7.

    Key 8
    -----
    ON  Remote mode
    OFF Local mode

SW3 Key 8 determines the disk drive initiation condition. When the
drive is in remote mode, the control unit initiates the drive and
rotates the disk by issuing the PICK/HOLD signal. In local mode the
disks rotate as soon as the power is turned on.

Terminal SW4 Main PCA
---------------------
Keys 1, 2, 3, 4, 5.
These keys must not be moved. They are factory settings only.

    Key 6
    -----
    ON  Runt sector enabled
    OFF Runt sector disabled

When this key is ON and the track capacity cannot be divided by the
number of sectors, the last dummy sector is shorter than usual. When
this switch is OFF, the last sector is longer than usual.

    Key 7
    -----
        ON      Vertical mounting (on side)
        OFF     Horizontal mounting

This key adjusts the servo characteristics that depend on the
orientation of the drive.

NOTE : A wrong setting may cause seek or write offtrack errors.

    Key 8
    -----
    ON  Release timer period = 1500 milliseconds
    OFF Release timer period = 500 milliseconds
                (See SW2 Key 3 for further details)

 Terminal SW2 Main PCA
 ---------------------
 Key  1    2    Function
 -----------------------
     OFF OFF    Both channels enabled
     ON  OFF    Channel A disabled
     OFF ON     Channel B disabled
     ON  ON     Both channels enabled

These keys determine the connection state between the drive and the
control unit of the host computer. Key 1 corresponds to Channel A
while Key 2 to Channel B. The drive port is disconnected from the
control unit and all interface signals are disabled when each setting
is ON.

    Key 3
    -----
    ON  Release timer activated
    OFF Release timer not activated

When the release timer is activated, the drive reserved condition
shall be released automatically after the specified period in the
RESERVE command. (See SW4 Key 8). When not activated, the reserved
condition may be released only by a RELEASE command issued by the
controller.

    Key 4
    -----
    ON  Enable write protection
    OFF Disable write protection

    Key 5
    -----
    ON  Calibration seek performed
    OFF Normal

Calibration seek must be executed at any time the main PCA is
replaced to optimise the servo control coefficient. To execute the
calibration seek set key 5 to the ON position and turn on the power.
Calibration seek is performed automatically. After completion in
approx. 4 minutes the STOP LED will blink. Set key 5 to the OFF
position to put the drive in the READY state.

    Key 6
    -----
    ON  Set device type to M2391K/D
        OFF     Set device type to M2392K/D

    Keys    Number of bytes per sector
 --------------------------------------
      7     16384   (2^14)
      8      8192   (2^13)
      9      4096   (2^12)
     10      2048   (2^11)

The number of sectors per track is determined by the settings of SW1
Main PCA keys 1 to 10 and SW2 keys 7 to 10 which controls the number
of bytes per sector regardless of the sector mode setting (SW3 Key
6). The actual bytes/sector value is obtained by adding 2 to the
position setting value. The bytes/sector must be an even number.

Terminal SW1 Main PCA
---------------------
Setting the sector count : Use in conjunction with SW2 keys 7 to 10

 Keys Number of bytes per sector
 -------------------------------
   1   1024    (2^10)
   2    512    (2^9)
   3    256    (2^8)
   4    128    (2^7)
   5     64    (2^6)
   6     32    (2^5)
   7     16    (2^4)
   8      8    (2^3)
   9      4    (2^2)
  10      2    (2^1)

(See notes for SW2 keys 7 to 10)

Terminal SW1 Interface PCA
--------------------------
Spindle synchronisation mode :

 Key    1       2       3       Function
 -------------------------------------------
     Ignored Ignored   OFF      Program mode
     OFF     OFF       ON       Slave mode
     ON      OFF       ON       Master mode
     OFF     ON        ON       Self (local) mode
     ON      ON        ON       Master control mode

The mode is set by switch for the drive or command (program mode)
from the control unit through the interface.

    Key 4
    -----
    ON  Disable spindle sync from channel B
    OFF Enable spindle sync from channel B

In the ON position spindle sync mode is enabled only from channel A.

 Key  5   6
      ON  ON    Slave synch termination enabled
      OFF OFF   Slave synch termination disabled

 Key  7   8
      ON  ON    Master synch termination enabled
      OFF OFF   Master synch termination disabled

A pair of signal lines in a balanced differential type must be
terminated properly. The line termination is alread mounted in the
interface PCA and can be activated through keys 5 to 8.

Installation direction
----------------------
The drive may be installed either PCA up or on left edge (viewed from
the rear).

Mounting Kit
------------
It is recommended that the drive should be mounted in the special
mounting frame designed for this purpose.

Cooling
-------
Cooling should be provided to keep the temperature of the disk
enclosure within specified limits. An air flow of at least 1m(3)/min
is recommended.
