When jumpered, the master or C drive is selected. -DSP, when jumpered, indicates to the 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. There is another way to connect the drive LED. J4, pins 1 and 2, provide both an open collector drive signal and a current limiting resistor connectrd on the other end to +5V. The following table shows what the jumper settings should be various system configurations. +---------------+----------+-----------+----------+ | Jumper | 1 Drive | 2 Drive | 2 Drive | | Configuration | | Master | Slave | +---------------+----------+-----------+----------+ | -ACT | CLOSED | Note 1 | Note 1 | +---------------+----------+-----------+----------+ | -C/D | CLOSED | CLOSED | OPEN | +---------------+----------+-----------+----------+ | -HSP | OPEN | OPEN | Note 2 | +---------------+----------+-----------+----------+ | -DSP | OPEN | CLOSED | OPEN | +---------------+----------+-----------+----------+ Note 1. In a two drive system, it is possible to drive one LED with both drives. An external current limiting resistor is required. The -ACT and -HSP signals both connect to pin 39, -HOST SLV/ACT. They are therefore mutually exclusive. Note 2. If the disk drive is connected to some drive that requires that the signal, -DRIVE SLAVE PRESENT be supplied from the slave drive via the interface 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 disk 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 features which allow greater shock tolerance are the use of rugged media and shock mounts. To take full advantage of the shock mounts, it is necessary to provide a minimum of 0.1 inch clearance on both the top and sides of the drive. This clearance allows for movement of the drive during acceleration. Mechanically Isolated Mounting Points ------------------------------------- Ten base mounting points are provided to the customer. Each mounting point is mechanically isolated from the head/disk assembly. 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. Physical Description -------------------- The user interface is a 40 conductor cable with Molex p/n 15-47-3401 female header or equivalent. The interface allows up to two drives to be daisy chained together. The maximum cable length is two feet. Connector --------- The disk drive connector is a 40 conductor connector which consists of two rows of 20 male pins on 100 mil centers. The header part number is Molex p/n 7723 40A587, or equivalent. 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. Air Filtration System --------------------- Within the sealed enclosure, a 0.3 micro filter provides a clean environment to the heads and disks. Power Connector --------------- The drive has a 4 pin DC power connector mounted on the PCB. The recommended mating connector is AMP part number 1-480424-0 utilizing AMP pins, part number 350078-4 or equivalent. Cabling ------- Connect the power cable to J3. Connect the Task File interface cable to J2. Drive Mechanism --------------- A brushless DC direct drive motor rotates the spindle at 3600 RPM. The motor/spindle assembly is dynamically balanced to provide a 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. Installation of the Drive and Adapter Card ------------------------------------------ 1. Pick a device type that is equal to or less than the CP344 in capacity and update the PC's CMOS drivers. 2. Remove power to the computer 3. 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 select the alternate address for the hard disk. 4. Insert the board into any available card slot. 5. 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 Note: 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. E3 E4 o o o 6. Connect power to the Disk Drive. 7. Run the DOS FDISK program (or equivalent) to establish DOS partitions. Note: DOS 3.2 and below have limitations of 32 megabytes unless software utility is used to overcome this. 8. Run the DOS format program 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 "/S" option was used. The system will ask for a volume name if the "/V" option is used. 9. Files can then be copied to the C: drive from the floppy. 10. 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 CP344 PRODUCT MANUAL 00501-001 REV. 1 Key Features ------------ The CP344 is a high performance 3.5 inch 21.4 megabyte (formatted) disk drive designed to operate on IBM PC/AT or equivalent in either native or translate mode. The CP344 also features low power require- ments enabling battery operation in portable environments. 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. - The CP344 features low power requirements, enabling battery opera- tion in portable environments - 1 : 1 Interleave - 8K Buffer - Read Lock-Ahead Capability - High performance rotary voice coil actuator with embedded servo system - Two of seven run length limited code - Sealed HDA - Internal air filtration - Microprocessor-controlled diagnostics routines that are auto- matically executed at start-up - Automatic error correction and retries - Block size 512 bytes - Emulates Task File and supports additional commands - Up to two drives may be daisy-chained on this interface - Translate mode (17 sectors, 5 heads, 980 cylinders) is supported Seek Times ---------- +----------------------------------+--------+ |Physical track to track max. | 10 ms | +----------------------------------+--------+ | Average msec. max. | 29 | | Average msec. max. | 50 | +----------------------------------+--------+ |Latency msec. avg. | 8.33 | +----------------------------------+--------+ Average seek time is determined by dividing the total time required to seek between all possible ordered pairs of track addresses, by the total number of these ordered pairs. Functional Description ---------------------- The CP344 contains all necessary mechanical and electronic parts 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 head selection, read preamplification, and write drive circuitry. The single microprocessor controlled circuit card provides the remaining electronic functions which include: - Read/Write Circuitry - Rotary Actuator Control - Interface Control - Spin Speed Control - Dynamic Braking - Power Management At power down (or the start of STANDBY MODE) the heads are auto- matically retracted to the inner diameter of the disk and are latched and parked on a landing zone that is inside the data tracks. Read/Write Heads and Disks -------------------------- Data is recorded on 95mm diameter disk through 3370 type heads. Error Correction ---------------- The disk performs internal error correction. The error correction polynominal is capable of correcting one error burst with a maximum of 8 bits per 512 byte block. Reliability and Maintenance --------------------------- MTBF 20,000 hours POH (population is min. of 100 units) MTTR 5 minutes typical Preventive Maintenance None Component Design Life 5 years Safety Standard --------------- The disk drive is designed to comply with relevant product safety standards such as: - UL 478 Electronic Data Processing Units and Systems - CSA C22.2 No.154, Data Processing Equipment - VDE 0804 Regulations for Telecommunications Apparatuses including Information Processing Equipment - IEC 435 Safety Requirements for Data Processing Equipment Write Precompensation --------------------- An 8 bit register used in previous disk drives to define the cylinder at which precompensation would begin. This register is used for other purposes in the CP344. Formatting ---------- Conner drives are different from previous ST506 type drives in that they do not require a low level format. This low level format is done in the factory as part of the extebded burn in process and it not possible to do via the Host interface, therfore to put a drive on a system, it is only necessary to FDISK and then do a system FORMAT. Evaluation Adapter Board ------------------------ In order to facilitate evaluation and aid those manufacturers interested in quickly getting the disk drive running, Conner Peripherals has developed an adapter board to be used in conjunction with the drive on an AT or equivalent system. The drive requires no special driver program as it works with the existing AT Bios or equivalent. It is hoped that the interface will be incorporated into the motherboard of the AT device or on some other multi-function adapter. The artwork and Bill of Materials are available upon re- quest.
