II, 10/1990 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.

Recommended Mounting Configuration ---------------------------------- The CP3044 is designed to be used in applications where the unit may experience shock and vibrations at greater levels than larger and heavier disk drives. Shock Tolerance Features ------------------------ 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. Mechanically Isolated Mounting Points ------------------------------------- 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 Connectors ---------------- The CP3044 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 CP3044 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. Acoustic Noise -------------- The sound pressure level will not exceed 40dBA at a distance of 1 meter from the drive. Drive Mechanism --------------- A brushless DC direct drive motor rotates the spindle at 3557 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 --------------------- 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. 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 For CP3044, always jumper E4. 5. Connect power to the CP3044. 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. ********************************************************************** F E A T U R E S ********************************************************************** CONNER CP3044 PRODUCT MANUAL REV. II, 10/1990 Key Features ------------ Key features of the CP3044 include: - Low power requirements enabling battery operation in portable environments - High performance rotary voice coil actuator with embedded servo system - High shock resistance - Internal air filtration system - 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 - Block size: 512 bytes - Emulates IBM Task File and supports additional commands - Up to two drives may be daisy-chained on this interface - Translate mode (17 sectors, 4 heads, 980 cylinders) is supported - Look Ahead Read Capability - AC Hysteresis on interface - 8K buffer Seek Times ---------- +----------------------------------+--------+ |Track-to-Track msec. | 8 | +----------------------------------+--------+ | Average msec. typ. | 25 | | Average msec. max. | 50 | +----------------------------------+--------+ |Latency msec. avg. | 8.4 | +----------------------------------+--------+ Functional Description ---------------------- The CP3044 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 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 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 CP3044 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 CP3044 will not come ready. Reliability and Maintenance --------------------------- MTBF 100,000 hours (POH) MTTR 10 minutes typical Preventive Maintenance None Component Design Life 5 years 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 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 | | 03 |sector buffer error | | 8x |slave drive failed (see note below)| +----------+-----------------------------------+ NOTE 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. +-----------------+---+---+----+----+---+----+---+---+----+---+ |Commands |BBK|UNC|IDNF|ABRT|TK0|DRDY|DWF|DSC|CORR|ERR| +-----------------+---+---+----+----+---+----+---+---+----+---+ |Recalibrate | | | | V | V | V | V | V | | V | |Read Sector | V | V | V | V | | V | V | V | V | V | |Read Sec.
