Jumpers
CONNER CP3024 PRODUCT MANUAL 00501-012 REV. I.1
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. +--------------+--------+---------------+--------------+ |Jumper | | | | |Configuration |1 Drive |2 Drive Master |2 Drive Slave | +--------------+--------+---------------+--------------+ | ACT | J | Note 1 | Note 1 | +--------------+--------+---------------+--------------+ | C/D | J | J | NJ | +--------------+--------+---------------+--------------+ | HSP | NJ | NJ | Note 2 | +--------------+--------+---------------+--------------+ | 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.
