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

 C/D Master/Slave Configuration
 ------------------------------
 CLOSED  Single Drive
 CLOSED  Master Drive
 OPEN    Slave Drive


 A/C Master/Slave Protocol
 -------------------------
 CLOSED  ATA/CAM master/slave mode
 OPEN    Conner master/slave mode


 Pins 5 16 RESERVED


 Master/Slave Configuration
 --------------------------
 When two drives are daisy-chained on the host interface, one must be
 designated as the master drive (C: drive) and one as the slave drive
 (D: drive). Commands from the host are written in parallel to both
 drives.

 When the C/D jumper on the drive is closed, the drive will assume the
 role of a master. When C/D is open, the drive will act as a slave. In
 single-drive configurations, C/D must remain in the closed (master)
 position.

 For each command sent from the host, the DRV bit in the drive/head
 register selects the master or the slave drive. When the DRV bit is
 reset (0), the master drive is selected, and when the DRV bit is set
 (1), the slave drive is selected.

 Once the drive receive the command, only the drive with jumper C/D
 set to the appropriate position will execute the command. For
 example, if the DRV bit is set, only the slave drive (jumper C/D
 open) will execute the command.

 NOTE
 If the command is a diagnostic command, both drives will execute the
 command and the slave will report its status to the master via the
 Host PDIAG signal.

 Throughout this manual, drive selection always refers to the state of
 the DRV bit and the position of the C/D jumper.

 The drive supports two master/slave modes via the A/C jumper. When
 A/C is closed, ATA/CAM master/slave mode is selected. When A/C is
 open, Conner master/slave mode is selected.


 Supported Master/Slave Modes
 ----------------------------
 There are three different master/slave methods that Conner supports.

   - ISA Original
   - Conner
   - ATA/CAM

 Of these three methods, the drive supports all except ISA/Original
 mode, with which is compatible.

 NOTE
 The ATA/CAM master/slave method is not compatible with the other two
 methods. The Conner mode is backward-compatible to the ISA Original
 mode, but is not compatible with the other.

 These three methods are explained in the following sections. For
 signals followed by a ' ', activate means go low and deactivate means
 go high.


 ISA Original Master/Slave
 -------------------------
 The signals used for master/slave operation and determination are
 Host DASP  and Host PDIAG .

 Host DASP  can be used to:

  - drive an activity LED
  - indicate that the slave drive is present to the master

 The Host PDIAG  is used to indicate that the slave has passed
 diagnostics both at power-on reset (POR) and when the diagnostic
 command is issued.

 At power-on time, the slave drive activates Host PDIAG  and Host
 DASP . Host PDIAG  remains activated from POR until a diagnostic
 command is issued by the host. Once a diagnostic is issued by the
 host, the slave deactivates Host PDIAG  until either:

  - the slave successfully completes the diagnostic command
  - the host issues a reset

 There are no real timing constraints on Host PDIAG  and Host DASP .
 At POR, they are both activated within a second or two. When the
 diagnostic command is issued by the host, the slave inactivates Host
 PDIAG  within 100-200 microseconds and is required to reactivate it
 within 5 seconds (the only timing constraint) if it successfully
 completes the command.

 This scheme works fairly well except for two problems:

 - There is no way to tell when the slave becomes ready. If the slave
   becomes ready much later than the master, the slave will miss any
   command that are issued before it goes not busy because the host
   only polls the master to see if the "controller" is ready.

 - In a two-drive configuration, the Host DASP  line is not available
   to drive a drive activity indicator.

 This version of master/slave is present on generations 1, 2, and 3
 of Conner drives.


 Conner Master/Slave
 -------------------
 To remendy the problem of the host not knowing when the slave was
 ready, Conner developed a backward-compatible solution, which we call
 Conner Master/Slave.

 In Conner Master/Slave, the use of the Host PDIAG  signal has been
 changed slightly during reset so that the slave will indicate when it
 will go not busy. Its use in the diagnostic command has not been
 changed.

 During POR or any host reset, the slave drive activates Host PDIAG
 within 1ms. The master drive waits slightly longer that 1 ms for
 Host PDIAG  to be activated before it determines that no slave is
 present. The slave then deactivates Host PDIAG  when it is ready. The
 master waits:

 - up to 14 seconds for the slave to deactivate Host PDIAG on either
   a POR or a host reset

 - 450 ms for the slave to deactivate Host PDIAG  on a host software
   reset

 If the master times out, it goes not busy.

 In this mode of master/slave, master/slave re-configures with either
 a hardware or software reset. A hardware reset is either a Power On
 Reset (POR) or host bus reset.

 This solution was implemented in generations 4 and greater of Conner
 drives.


 ATA/CAM Master/Slave
 --------------------
 This industry-standard master/slave solution was developed by the CAM
 shortly after the development of the Conner Master/Slave. The
 polarity of Host PDIAG  is opposite that of the Conner solution and
 this is what makes this master/slave scheme incompatible with the
 Conner scheme.

 At power-on time, the slave deactivates Host PDIAG  and then
 activates Host DASP  within 1 ms of either POR or host reset. Host
 DASP  activate indicates that a slave is present. The slave
 activates Host PDIAG  when it is ready to accept commands or after 30
 seconds, whichever occurs first. This period is reduced to 450ms for
 a software reset. A hardware reset is either a POR or host bus reset.

 This solution was implemented in generations 4.5 and greater of
 Conner drives and is selectable with the A/C jumper or the CAM bit in
 the feature word.

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

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


 Mounting the drive
 ------------------
 You can mount the drive either vertically or horizontally. The drive
 will meet all performance specifications when mounted at any
 orientation.

 CAUTION
 The surface(s) on which you mount the drive should be flat and
 parallel to prevent uneven pressure on the drive. Mounting the drive
 on an uneven surface could cause the drive's base to deform, degrad-
 ing drive performance.

 CAUTION
 When using the side mounting holes, verify the screw length to ensure
 clearance from the drive's pronted circuit board before tightening
 the screw.


 Data and Power Connections
 --------------------------
 The drive has a 40-pin data connector, as well as an auxiliary
 connector which is reserved for factory or evaluation use.

 The drive has two power connectors, only one of which should be used
 at a time. The two connectors provide connection versatility to a
 number of host systems.


 Power Connectors
 ----------------
 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.

 4-Pin Power Connector Pin 1 +12 Volts
                       Pin 2 GND
                       Pin 3 GND
                       Pin 4 + 5 Volts

 The mating connector for the 3-pin connector is Molex series 54-84
 (header), Molex part number 39-01-033 (housing), and terminal part
 number 39-00-0031 (loose) or 39-00-0023 (strip).

 3-Pin Power Connector Pin 1 + 5 Volts
                       Pin 2 +12 Volts
                       Pin 3 GND

 CAUTION
 Do not route the power cable next to the drive PCB or any other high
 frequency or large current switching signals. Improper drive opera-
 tion can result from improper cable routing.


 Task File Interface Connector
 -----------------------------
 The recommended mating connector for the Task File Interface is
 Molex P/N 15-47-5401 or equivalent. You may daisy-chain two drives on
 this connector. The maximum cable length is 18 inches.

 Pin 1 is typically indicated by a colored stripe on the data cable.

 CAUTION
 Do not route the data cable next to the drive PCB or any other high
 frequency or large current switching signals. Improper drive opera-
 tion can result from improper cable routing.


 Signal Levels
 -------------
 All signal levels are TTL compatible. A logic "1" is > 2.0 Volts. A
 logic "0" is from 0.00 Volts to 0.70 Volts.


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

 The CFS210A contains:

 - one disk with two data surfaces
 - two read/write heads

 The CFS420A contains:

 - two disks with two data surfaces each
 - four read/write heads

 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.

 Key Features
 ------------
 The Conner Filepro Series CFS210A and CFS420A are high-performance
 low-profile drives that are designed to operate with an IBM PC/AT or
 equivalent host computer system in translate mode.

 The drive provides these features:

 - can be installed in a wide range of host systems

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

 - 1/7 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.

 - Read Look Aehad and optional Write Caching

 - Automatic error correction and retries, ECC on the fly

 - Block size 512 bytes

 - 32K Buffer with adaptive cache management

 - emulates IBM Task File and supports additional commands

 - allows daisy-chaining up to two drives on the AT interface

 - Auto-Translate (Universal Translate)

 - 4-byte ECC diagnostic check in read/write

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

 - ATA/CAM (AT Attachment/Common Access Method)

 - ISA/Conner (Industrie-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 only by the maximum capacity of the drive. Upon initial
 power up to the drive it will default to a configuration shown below:

          Cylinders        Heads       Sectors
 CFS210A     685            16           38
 CFS420A     826            16           63

 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 drive will
 then:

 - calculate the total number of available logical tracks based upon
   the entered sector and head values

 - save the drive parameters in non-volatile memory for subsequent
   drive operations


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

       +----------------------------------+--------+
       |         track to track      max. |   3 ms |
       +----------------------------------+--------+
       |               Average msec.      |  14    |
       |               Average msec. max. |  26    |
       +----------------------------------+--------+
       |Latency                msec. avg. |   8.3  |
       +----------------------------------+--------+
       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 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.


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


 Task File Interface Signal Connector Pin 28
 -------------------------------------------
 Pin 28 +Spindle Sync/Cable Select (I/O)
 Optional. This signal may optionally be used for two functions. Some
 systems, however, may require this pin to be isolated because it was
 defined as ALE prior to the ATA specification.

 - Spindle Sync is a signal used by the drives which are interconnect
   on the same cable to synchronize their spindle rotation with each
   other.

 - Cable Select routes the C/D select to this spin. When set high,
   drive D: is selected; when set low, drive C: is selected.


 Error Correction
 ----------------
 The drives use a Reed-Solomon code to perform error detection and
 correction. For each 512-byte block, the software error correction
 polynominal is capable of correcting:

 - one error burst up to 22 bits

 - two error burst up to 11 bits each

 Single bursts of 11 bits or less are corrected on the fly (OTF) with
 no performance degradation.


 Execute Drive Diagnostic
 ------------------------
 Command Number: 90 hex

 Description
 This command performs the internal diagnostic tests implemented by
 the drive. The diagnostic tests are only executed upon receipt of
 this command.

 The drive sets BSY immediately upon of the command. If the drive is a
 master, 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 diagostics, it asserts -HOST PDIAG.
 If unsuccessful, the master drive resets BSY in the Status register
 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 inter-
 face registers are set to initial values except for the Error
 register.

 The table below details the codes in the Error register and a
 corresponding explanation.

 Error Code    Description
 01 hex        No error detected
 02 hex        Format device error
 03 hex        Sector buffer error
 8x hex        Slave drive failed

 Additional codes may be implemented at the manufacturer's option.

 NOTE
 If the slave drive fails diagnostics, the master drive shall "OR" 80
 hex with its own status and load that code into the Error register.
 If the slave drive passes diaagnostics or there is no slave drive
 connected, the master drive shall sect bit 7 of the Error register
 Task File to 0.


 Reliability and Maintenace
 ---------------------------
 MTBF                     250,000 hours POH
 MTTR                     10 minutes typical
 Preventive Maintenance   None
 Component Design Life    5 years
 Start/Stop Cycles        20,000 minimum


 Drive Motor and Spindle
 -----------------------
 A brushless DC direct-drive motor assembly is mounted on the drive's
 base. The motor rotates the spindle at 3600 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.


 Safety Standard
 ---------------
 The drive is designed to comply with relevant product safety
 standards, including:

 - UL 478, 5th edition, Standard for Safety of Information Processing
   and Business Equipment, and UL 1950, Standard for Safety of
   Information Technology Equipment

 - CSA 22.2#220, Information Processing and Business Equipment,
   CSA 22.2#950, Safety of Electrically Energized Office Machines

 - IEC 380, Safety of Electrically Energized Office Machines, and
   IEC 950, Safety of Information Technology Equipment Including
   Electrical Business Equipment

 - VDE 0805, VDE 0805 TIEL 100, VDE 0806

 - Complies with FCC Class B, Part 15, Subpart J
