This feature is dependent on two drive settings; the status of hardware Jumper M/S and the firmware setting of a feature bit. When (M/S) is closed, and the feature bit is set, the drive will assume the role of a Master Drive. When (M/S) is open, and the feature reset, the drive will act as the Slave. In single drive configurations M/S must remain in the closed position. ********************************************************************** I N S T A L L ********************************************************************** CONNER CP2124 PRODUCT MANUAL REV.

Recommended Mounting Configuration ---------------------------------- This CP2124 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. Four (4) side mounting points and four (4) bottom mounting points are provided to the customer. The drive is mounted using 3mm x 0.5mm thread screw. The screw insertion depth should not exceed 4mm into the mounting holes. The system integrator should allow ventilation to the drive to ensure reliable drive operation over the operating temperature range. For additional vibration isolation, an external suspension system may be used. Interface Connector ------------------- The CP2124 drive has a 44 pin right angle interface/power connector mounted on the PCB. The recommended mating connector is DuPont part number 69764-044 or equivalent. The maximum cable lenght is two feet. Diagnostic Routines ------------------- The microprocessor performs diagnostics upon application of power. If an error is detected the drive will not come ready. Magnetic Field -------------- The externally induced magnetic flux density may not exceed 6 gauss (DC - 700KHz) or 1.0 gauss (700KHz - 1.5MHz) as measured at the drive surface. Acoustic Sound Emission ----------------------- Pressure: The sound pressure level for the operating drive will not exceed 34 dB(A) max. at a distance of 1 meter from the drive. ********************************************************************** F E A T U R E S ********************************************************************** CONNER CP2124 PRODUCT MANUAL REV. II 1/1992 Key Features ------------ The CP2124 is a newest addition to a family of high performance 2.5 inch low-profile disk drives with formatted capacity 121.6 megabytes. The drive has a 16 ms average seek time and is designed to operate on IBM PC/AT or equivalent computers. The drives feature a low 5V power requirement and high shock resistance, enabling battery operation in a portable environment. - 2.5" Form factor - Single 5 Volt supply - Low power requirements - 7 oz unit weigth - High performance rotary voice coil actuator with embedded servo system. - Single connector for power & interface - Run length limited code (one of seven) - High shock resistance - Internal air filtration system - Sealed HDA - Automatic actuator latch over data free landing zone during standby mode or power-down - Microprocessor-controlled diagnostics routines that are auto- matically executed at start-up. - Automatic error correction and retries - Block size 512 bytes - PC AT Interface - 1:1 sector interleave - Automativ read look ahead - 32K Buffer - Master/Slave Seek Times ---------- +----------------------------------+--------+ |Physical track to track max. | 5 ms | |Logical max. | 10 ms | +----------------------------------+--------+ | Average msec. typ. | 17 | | Average msec. max. | 35 | +----------------------------------+--------+ |Latency msec. avg. | 7.99 | +----------------------------------+--------+ 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 drive is operated using its translation parameters. 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. Functional Description ---------------------- The CP2124 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 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 A microprocessor performs diagnostics upon application of power. If an error is detected the drive will not come READY. At power down or the start of STANDBY MODE or SLEP MODE 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. Drive Mechanism --------------- A brushless DC direct drive motor rotates the spindle at 3486 RPM. The motor/spindle assembly is dynamically balanced to provide minimal mechanical run-out to the disks and to reduce vibration of the HDA. A dynamic brake is used to provide a fast stop to the spindle motor and return the heads to the landing zone inside the data tracks when power is removed or upon initiation of STANDBY MODE. Air Filtration System --------------------- Within the sealed enclosure, a 0.3 micron filter which provides a clean environment for the heads and disks. Head Positioning Mechanism -------------------------- The read/write heads for the CP2124 is supported by a mechanism coupled to the voice coil actuator. Read/Write Heads and Disks -------------------------- Data is recorded on 65mm diameter thin film disk through micro- miniature THIN FILM or MIG heads. The 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. 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 predetermined configura- tion shown below: Cylinders Heads Sectors CP-2124 762 8 39 Error Correction ---------------- The CP2124 drive use a Reed-Solomon code to perform error detection and correction. The error correction polynominal is capable of correcting one error burst with a maximum of 22 bits or 2 error bursts of up to 11 bits each, per 512 byte block. Single bursts of 11 bits or less are corrected 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 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.
