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

 Customer Options
 ----------------
 There are four jumper options available for configuration:
 HSP, C/D, DSP, and ACT.

 HSP, when jumpered, connects the -HOST SLV/ACT signal on the inter-
 face to ground for systems that require the slave drive to provide
 -SLAVE PRESENT signal in a two-drive system.

 C/D is the address jumper. When jumpered, the master (or C drive), is
 selected. When open, the slave (or D drive), is selected.

 DSP, when jumpered, indicates to the master drive that a slave is
 present. In a two-drive system, this jumper option must be installed
 in the master, or C drive.

 The last jumper, ACT, connects the -ACTIVE signal to the -HOST
 SLV/ACT signal on the interface. This signal provides the capability
 to drive an external LED. An external current limiting resistor is
 required.

 As an alternative, an LED may be connected between J4, pins 1 and 2.
 This would provide both an open collector drive signal and a current
 limiting resistor connected to +5V respectively.

 The following table shows what the jumper setting should be for
 various system configurations.
   +--------------+--------+---------------+--------------+

   |    DSP       |   NJ   |      J        |    NJ        |
   +--------------+--------+---------------+--------------+

 NOTE 1:
 In a two drive system, it is possible to drive one LED with both
 drives. An external current limiting resistor is required.


 NOTE 2:
 If the drive is connected to a host that requires that the signal
 -DRIVE SLAVE PRESENT be supplied from the slave drive, via the inter-
 face signal -HOST SLV/ACT, then this jumper must be installed. If
 this jumper is installed, the ACT jumper must not be installed
 because the two jumpers are mutually exclusive.

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

 The drive may be mounted in any attitude!


 Recommended Mounting Configuration
 ----------------------------------
 The CP3024 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
 assemblies.

 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 ventila-
 tion to the drive to ensure reliable drive operation over the opera-
 ting temperature range.


 Power Connector
 ---------------
 The CP3024 has a 4-pin DC power connector (J3) mounted on the PCB.
 The recommended mating connector is AMP part number 1-480424-0
 utilizing AMP pins (part number 350078-4 or equivalent).
 DC power may also be supplied to the drive throughh a 3 pin
 connector (J5). The recommended mating connector is Molex part number
 39-01-0033 utilizing Molex pins (part number 39-00-0031 or equiva-
 lent).

 Power is to be supplied at either J3 or J5, but not both.


 Task File Interface Connector
 -----------------------------
 The CP3024 has a 40-pin Task File Interface connector (J2) mounted on
 the printed circuit board. The recommended mating connector is Molex
 part number 10-91-2401 or equivalent. Two drives may be daisy chained
 together at this connector. Maximum cable length is two feet.


 Magnetic Field
 --------------
 The externally induced magnetic flux density may not exceed six gauss
 as measured at the disk surface.


 Acoustic Noise
 --------------
 40 dBA maximum at one meter.


 Drive Mechanism
 ---------------
 A brushless DC direct drive motor rotates the spindle at 3575 rpm.
 The motor/spindle assembly is balanced to provide minimal
 mechanical runout to the disk. A dynamic brake is used to provide a
 fast stop to the spindle motor when power is removed, or upon
 initiation of STANDBY MODE.


 Air Filtration System
 ---------------------
 Within the sealed enclosure, a 0.3 micron filter provides a clean
 environment to the heads and disks.



 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
     controller.

  3. Insert the board into any available card slot.

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

     Adapter Card Jumpers   E1 and E3 always not installed
                            E2 and E4 always installed

  5. Connect power to the CP3024.

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

      Note: DOS 3.2 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.

 Functional Description
 ----------------------
 The CP3024 contains all mechanical and electronic parts necessary
 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
 one of two head selection, read pre-amplification, and write data
 circuitry.

 The single microporcessor-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 or the starts of STANDBY MODE, 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.


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


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


 Error Correction
 ----------------
 The CP3024 performs internal error correction. The error correction
 polynominal is capable of correcting one error bursts with a maximum
 of 8 bits per 512-byte block.


 Diagnostic Routines
 -------------------
 The microprocessor performs diagnostics upon application of power. If
 an error is detected, the CP3024 will not come ready.


 Reliability and Maintenance
 ---------------------------
 MTBF                     20,000 hours (POH); population is minimum of
                          100 units
 MTTR                     10 minutes typical
 Preventive Maintenance   None
 Component Design Life    5 years


 Safety Standard
 ---------------
 The CP3024 disk drive is designed to comply with relevant product
 safety standards such as:

 - UL 478 Electronic Data Processing Units and Systems
 - CSA 22.2 No. 154 Data Processing Equipment

 - IEC 435 Safety Requirements for Data Processing Equipment.
