Jumper Setting

Up to two drives may be daisy chained together utilizing the 40 pin
Task File connector. The maximum cable length is 18 inches. In order
to install more than one drive, it is necessary to set a jumper
option. The C/D jumper is used to determine whether the drive is a
master (drice C) or slave (drive D). The drive is configured as a
master (drive C) when jumpered and as a slave drive (D drive) when
not jumpered.

 This pair of jumpers determines the signals on pin 39 of the inter-
 face connector.

 Master/slave in CAM compatible mode uses pin 39 in a time multiplexed
 manner to indicate that a slave drive is present. During power-on-
 reset or after RESET is asserted, this line is asserted by the slave
 drive within 400 ms to indicate its presence. The master drive allows
 up to 450 ms for the slave drive to assert -HOST SLV/ACT. -HOST SLV/
 ACT is deasserted by the slave drive following its acceptance of the
 first valid command or after 31 seconds, whichever comes first.

 E1 Jumper in disables spin-up at power-on. The drive will
    automatically spin up when it receives a command which accesses
    the drive.

Conner Master Slave
The drive is equipped with a -C/D jumper. To select the drive as the
master, in a two drive or ported system, or a single drive, the -C/D
jumper should be installed. If the jumper is not installed, the drive
will configure as the slave. The -PDIAG line is used as the slave
present signal to the master in the following way.

At power on time -PDIAG will be activated by the slave within 1 ms.
If the master does not see -PDIAG active after 4 ms it will assume no
slave is present. -PDIAG will remain active until the slave is ready
to go not busy or 14.0 seconds after a Power On Reset. The master
will wait 14.5 seconds or until the slave deactivates -PDIAG on Power
On Reset before it goes not busy. The slave will deactivate -PDIAG
and go not busy, if it is not ready after the 14.0 seconds. Neither
drive will set Ready or Seek Complete until they have reached full
spin speed and are ready to read and write.

During a software reset, -PDIAG will be activated by the slave within
1 millisecond. If the master does not see -PDIAG active after 4 ms it
will assume that no slave is present. The slave will not deactivate
-PDIAG until it is ready to go not busy or 400 ms. The master will
only wait 450 ms or until the slave deactivates -PDIAG before it goes
not busy. The slave will onnly wait 450 ms before it activates -PDIAG
and goes not busy. The drive will not set Ready or Seek Complete
until those states are achieved.

After Reset, -PDIAG is used in its normal diagnostic function during
the diagnostic command.

The drive will operate in all axis (6 directions).

Mounting Configuration
The drive is designed to be used in applications where the unit may
experience shock and vibrations at greater levels than larger and
heavier disk drives.

The design features which allow greater shock tolerance are the use
of rugged heads and media, a dedicated landing zone, closed loop
servo positioning and specially designed motor and actuator

Ten base mounting points are provided to the customer. The drive is
mounted using 6-32 x 1/8" max. insertion for the sides, and 1/4"
insertion for the bottom. The system integrator should allow
ventilation to the drive to ensure reliable drive operation over the
operating temperature range. The drive may be mounted in any

The system integrator should also allow 0.060 inches (1.6mm) of free
space and on each side of the drive for head-disk-assembly (HDA) sway
space if the drive is expected to need operating shock specifica-
tions. If the disk drive is mounted from sides, the mounting
provisions should clear the baseplate of the HDA.

 J3 Connector
 A drive select LED may be driven using two alternative pins on this
 drive. Pin 39 can be used to drive the LED if it is not configured
 for Spindle Synchronization. The 16-pin auxiliary connector (J3),
 pins 3 and 4 provide an open collector drive signal and a current
 limiting resistor connector to the other end of +5V.

The spindle synchronization signal is alternatively available on pin
2 of J3.

 The Auxiliary connector 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.

Power Connector
Power is supplied to the drive through a standard 4 pin DC power

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

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.

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.

Acoustic Noise
The sound pressure level will not exceed 40 dBA at a distance of 1
meter from the drive.

Installation of the Drive and Adapter Card

1. Remove power to the computer

  2. If another hard disk controller is installed, it is necessary to
     prevent it from responding to the addresses 1F0-7H and 3F6-7H.
     It is also necessary to ensure that the controller is
     electrically disconnected or tri-stated from IRQ14 of the mother-
     board bus. This may be done either by removing the board, by
     electrically disconnecting the signal from the interface, or by
     setting the jumpers of the board to disable the hard disk

3. Insert the board into any available card slot.

  4. Configure the Host adapter for the correct configuration of your
     computer BIOS.

                            E2 and E4 always installed

     E3 and E4 are located in a straight line with a pin between them,
     as shown below. Jumper in refers to the pin jumpered to the
     center pin.

5. Connect power to the drive.

6. Run the DOS FDISK program to establish DOS partitions.

      Note: DOS 3.3 and below have limitations of 32 megabytes unless
            software utility is used to overcome this.

  7. Run the DOS format programm by typing "Format C:/S". The volume
     may be named with the addition of the "/V". The format will be
     completed and the system transferred if the "/V" option was used.
     The system will ask for a volume name.

8. Files can then be copied to the C: drive from floppy.

  9. When the system is rebooted, the system should boot from the hard
     drive (Drive C:) if the floppy is removed.



Key Features
The CP3544 Summit is a high performance 3.5 inch half-height drive
with up to 544 Mbytes (formatted) capacity, 12 ms average seek time
and 6.7 ms average latency that is designed to operate on an IBM
PC/AT or equivalent in translate mode. The CP3364 is a de-populated
version of the Summit Series drive with 362 megabyte (formatted)
capacity and identical performance. These drives offer high perfor-
mance while maintaining low power consumption to reduce power supply
current and system cooling requirements in disk arrays. Typical
applications for this family of drives are workstations, file
servers, multiuser systems and disk arrays. These drives also have
the capacity to achieve over 1GB capacity in a standard AT master-
slave configuration.

Because the drive contains the Task File within its control logic, it
requires a simplified adapter board to operate. Conner Peripherals
has developed an adapter board to be used in conjunction with the
drive on an AT or equivalent system.

Seek Times
Track to Track 3.0 ms
Average 12.0 ms
Maximum 30.0 ms

The timing is measured through the interface with the drive operating
at nominal DC input voltages. The timing is based upon the physical
parameters of the disk and may be affected by translation.

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

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
one of two head selection, read pre-amplification, and write data

The dual 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

At power the heads are automatically retracted to the inner diameter
of the disk. There they 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 4498 RPM.
The motor/spindle assembly is dynamically 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

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

Read/Write Heads and Disks
Data is recorded on 95mm diameter disk through 3370 type thin film

Error Detection and Correction (EDAC)
The drive uses a Reed-Solomon code to perform error detection and
correction. The polynominal is able to detect a single burst of up
to 51 bits in length or up to three bursts each of which may be up
to 11 bits in length.

The error correction cabability of the polynominal is a single burst
with a maximum length of 22 bits or two independent error bursts of
up to 11 bits each per 512 byte block. A single burst of 11 bits or
less is corrected "on-the-fly" with no performance degradation. The
miscorrection probability using this "on-the-fly" error correction is
superior to the detection capability of the traditionally used 56 bit
computer generated code.

Execute Drive Diagnostic - 90
This command runs the internal diagnostic tests implemented by the
drive. The diagnostic tests shall only be executed upon receipt of
this command.

The drive sets BSY immediately upon receipt of this command. If the
drive is a master (C/D jumpered) the drive performs the diagnostic
tests and saves the results. It then checks to see if a slave drive
is present and waits up to 5 seconds for the slave to complete its
diagnostics. If the slave successfully completes its diagnostics, it
asserts -HOST PDIAG.

If the slave does not successfully complete its diagnostics, it sets
the error register as follows. The master drive resets BSY,
and generates an interrupt. The Error bit (ERR) is set in the
Status Register and the Error Register is updated.

The value in the error register should be viewed as a unique 8 bit
code and not as the single bit flags defined previously. The
interface registers are set to initial values except for the error
register if error.

 The table below details the codes in the error register and a
 corresponding explanation:
 |Error Code|Description                        |
 |    01    |no error detected                  |
 |    02    |format device error                |
 |    03    |sector buffer error                |
 |    8x    |slave drive failed (see note below)|

If the slave drive fails diagnostics, the master drive shall "OR"
80H with its own status and load that code into the error register.
If the slave drive passes diagostics or there is no slave drive
connected, the master drive shall set bit 7 of the Error Register in
the Task File to 0.

Error Reporting
In general, errors are detected in the following fashion by the
drive microprocessor. At the start of this execution of the command,
the command register is checked for conditions that would lead to an
aborted command. Then the operation is attempted. Ayn subsequent
error terminates the command at the point that is discovered. The
errors that are valid for each command are summarized in the follow-
ing matrix. Any subsequent error terminates the command at the point
that it is discovered.
