Jumpers

CONNER CP30084E/30174E PRODUCT MANUAL 00501-047 REVISION A

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

Master/Slave Configuration
--------------------------
The drive is designed to operate either as a Master Drive (C Drive)
or a Slave Drive (D Drive). This feature is dependent on two drive
settings; the status of hardware Jumper Master/Slave and the firmware
setting of a feature bit. When the jumper is closed the drive will
assume the role of a Master Drive. When the jumper is open the drive
will act as the Slave. In single drive configurations the jumper must
remain in the closed position. The feature word 132, bit 8 determines
if the drive will act according to ATA/CAM or ISA/Conner protocol
during master/slave detection.

When two drives are daisy chained on the interface, commands are
written in parallel to both drives, only the selected drive will
execute the command, except for the diagnostic. In that case, both
drives execute the command and the slave reports its status to the
master via the -HOST-PDIAG signal.

Drives are selected by the DRV bit in the drive/head Register and by
a jumper, on the drive designating it as either master or slave.
When the DRV bit is reset, the master drive is selected, and when
the DRV bit is set, the slave drive is selected. When drives are
daisy chained, one must be jumpered as the master and one as the
slave. When a single drive is attached to the interface, it must be
jumpered as the master.

J5 Auxiliary Connectors
------------------------
The Auxiliary connector J5 is used to provide optional signals at the
front of the drive. No connection should be made to the pins marked
RESERVED. These pins are reserved for factory test purposes and
improper connection may adversely affect the drive.

   +----+-----------+-----+----------+

CONNER CP30084E/30174E PRODUCT MANUAL 00501-047 REVISION A

Notes on Installation
=====================

Screws
------
6-32 UNC 2B, 5/32" MAX (6x) side.
6-32 UNC 2B, 3/8" MAX (4x) bottom.

Power Connectors
----------------
The mating connector for the four pin connector is AMP 1-480424-0
(Housing) and AMP 60619-4 (loose piece) or 61117-4 (strip) contacts.

The mating connector for the three pin connector is Molex series
54-84 Header, housing Molex part number 39-01-0033 and terminal part
number 39-00-0031 (loose) or 39-00-0023 (strip).

Magnetic Field
--------------
The disk drive will meet its specified performance while operating in
the presense of an externally produced magnetic field under the
following conditions.

   +------------------+------------------+
   |Frequency         |   Field Intensity|
   +------------------+------------------+
   |   0 to 700 Khz   |   6 gauss maximum|
   | 700Khz to 1.5Mhz |   1 gauss maximum|
   +------------------+------------------+

Acoustic Noise
--------------
The sound pressure level will not exceed 42 dBA in any mode at a
distance of 1 meter from the drive.

Host Interface
--------------
The interface between the drive adapter and the drive is called the
Host Interface. The set of registers in the I/O space of the Host
controlled through the Host Interface is known as the Task File. The
physical interface from the drive to the host is implemented using a
40 pin connector.

Care must be exercised with the routing of the power and signal
cables. They should not be routed next to the drive PCB or other high
frequency or large current switching signals. Improper drive opera-
tion can result from improper cable routing.

Interface Connector
-------------------
The recommended Mating Connector is Molex P/N 15-47-3401 or
equivalent. Two drives may be daisy chained on this connector, and
the maximum cable length is 18 inches.

Signal Levels
-------------
All signal levels are TTL compatible. A logic "1" is > 2.0 Volts. A
logic "0" is from 0.00 Volts to .70 Volts.

Features

CONNER CP30084E/30174E PRODUCT MANUAL 00501-047 REVISION A

Key Features
------------
The CP30084E Jaguar is a high performance 3.5 inch low-profile (1
inch high) 85 megabyte (formatted) disk drives with 17 ms average
seek time, that is designed to operate on an IBM PC/AT or equivalent
in translate mode. The CP30174E Jaguar is a double-capacity
configuration of the Jaguar Series with 170 Mbytes (formatted)
capacity in the same form factor, with the same performance. The
drives feature low power requirements and high shock resistance,
enabling battery operation in portable environments.

Because the drive contains the Task File within its control logic, it
requires a simplified adapter board to operate.

- 85 and 170 Mbyte capacities.

 - Low power requirements enabling battery operation in portable
   environments.

 - High performance rotary voice coil actuator with embedded servo
   system.

- One of seven run length limited code.

- High shock resistance

- Sealed HDA

- Automatic actuator latch against inner stop upon power-down.

 - Microprocessor-controlled diagnostics routines that are auto-
   matically executed at start-up.

- Automatic error correction and retries, ECC on the fly.

- 512 bytes block size, 32K buffer.

- Emulates IBM Task File and supports additional commands.

- Up to two drives may be daisy-chained on the AT interface.

- Auto Translate mode for AT is supported.

- 4 Byte ECC diagnostic check in write/read.

- Automatic read look ahead.

The drive supports either of the following MAster/Slave protocol
standards:

   - ATA/CAM (AT Attachment/Common Access Method)
   - ISA/Conner (Industry Standard Architecture)

Universal Translate Mode
------------------------
Conner has established a Universal Translate Mode which enables the
user to configure the drive in an aT environment to any cylinder,
head, and sector configuration desired. The translate configuration
is limited by the maximum capacity of the drive it will default to a
predetermined configuration shown below:

             Cylinders    Heads    Sectors
    CP30084E   903          4        46
    CP30174E   903          8        46

After the drive is ready, the host system may issue INIT DRIVE PARMS
COMMAND (command code 91H) to alter the translate configuration
(number of heads and number of sectors per track). The total number
of available logical tracks based upon the entered sector and head
values will be calculated. The drive parameters will then be saved in
EPROM for subsequent drive operations. These values are defined and
used in the Conner specific (9A) and Identify Drive (EC) commands.

Seek Times
----------

       +----------------------------------+--------+
       |Track-to-Track         msec.      |   3    |
       +----------------------------------+--------+
       |               Average msec. typ. |  17    |
       |               Average msec. max. |  30    |
       +----------------------------------+--------+
       |Latency                msec. avg. |   7.8  |
       +----------------------------------+--------+
       The timing is measured through the interface with the drive
       operating at nominal DC input voltages. The timing also assumes
       that:
             - BIOS and PC system hardware dependency have been
               subtracted from timing measurements.

             - The drive is operated using its translation drive
               parameters.

       The average seek time is determined by averaging the seek time
       for a minimum of 1000 seeks of random length over the surface
       of the disk.

Functional Description
----------------------
The drive contains all necessary mechanical and electronic parts to
interpret control signals, position the recording heads over the
desired track, read and write data, and provide a contaminant free
environment for the heads and disks.

Read/Write and Control Electronics
----------------------------------
One integrated circuit is mounted within the sealed enclosure in
close proximity to the read/write heads. Its function is to provide
head selection, read pre-amplification, and write drive circuitry.

The single microprocessor-controlled circuit card provides the re-
maining electronic functions, which include:

        - Read/Write Circuitry
        - Rotary Actuator Control
        - Interface Control
        - Spin Speed Control
        - Dynamic Braking
        - Power Management

At power down the heads are automatically retracted to the inner
diameter of the disk and are latched and parked on a landing zone
that is inside the data tracks.

Drive Mechanism
---------------
A brushless DC direct drive motor rotates the spindle at 3822 RPM.
The motor/spindle assembly is balanced to provide minimal mechanical
runout to the disks. A dynamic brake is used to provide a fast stop
to the spindle motor and return the heads to the landing zone when
power is removed.

Air Filtration System
---------------------
The head-disk assembly is a sealed enclosure with an integral 0.3
micron filter which maintains a clean environment for the heads and
disks.

Head Positioning Mechanism
--------------------------
The read/write heads are supported by a mechanism coupled to the
voice coil actuator.

Read/Write Heads and Disks
--------------------------
Data is recorded on 95mm diameter disk through 3370 type heads.

Error Correction
----------------
The drive uses a Reed-Solomon code to perform error detection and
correction. The software error correction polynominal is capable of
correcting one error burst with a maximum of 22 bits or 2 error
bursts of up to 11 bits each, per 512 byte block. Single bursts of 11
bits or less are corrected on the fly with no performance degrada-
tion.

 Reliability and Maintenance
 ---------------------------
 MTBF                     150,000 hours (POH) base on field return
                          rates.
 MTTR                     10 minutes typical
 Preventive Maintenance   None
