A selectable option is provided to clear this latch. When the drive is in normal condition (no jumper is installed), this option resets the Write Fault latch when the Write gate is removed. It is reasserted after the Write Fault is cleared. The selected option (with jumper is installed) resets the Write Fault latch when the drive is not selected. It is reasserted after the Write Fault is cleared. RO - Radial Option ------------------- This option is used for multiple drives when cabled in a radial mode. DS1 - DS4 --------- Drive Select 1 - 4. ST - Self Test -------------- This option is used during the manufacturing of the drive. Self-test is not recommended for field use. This option causes the stepper motor to actuate the heads in a butterfly seek mode and it disallows control sent via the interface.

The OCTAGON KL320/330 may be mounted in any position. Twelve mount- ing holes are provided in the drive chassis for installation. Eight of these holes accept M4 metric screws; the remaining four holes accept #6-32 machine screws. Up to four drives may be mounted in a standard 3.25" x 5.75" x 8.0" space in a host system. Power dissipation for the KL320/330 drives is 11.0 watts (typical). Cooling, whether by air or fan, must be sufficient to keep both the drive and the host system within the required temperature range. In addition, 0.04-inch clearance must be provided for cooling, shock & vibration, and easy installation and removal. The KL 320/330 can be installed into any computer system that has a disk controller which supports the ST412/ST412-R (KL 330) interface. These products are ideal for ruggedized applications and specially suited where compact size, lightweight, high storage capacity, and reliability is required. Electrical Interface Requirements --------------------------------- Three types of connectors are required for the KL 320/330 electrical interface. Kalok recommends the following types or their equivalents: Name Part Number --------------------------------------------------- P1 (J1): Control Interface AMP 88373-3 P2 (J2): Data Interface AMP 88373-6 P3 (J3): Power Supply AMP 1-480424-0 (Housing) AMP 350078-4 (Pins) Cable Connections ----------------- For control and data interface, Kalok recommends twisted pair or flat ribbon cables. These cables should not be longer than 20 feet. In addition, the power cable should have twisted pair for each line voltage and return. MFM Write Data ------------- (J2 Pins 13 and 14) The MFM Write Data lines are input lines terminated by an RS-422 differential line receiver with 100 ohms input impedance. These lines should be driven by a standard RS-422 line driver. MFM Read Data ------------- (J2 Pins 17 and 18) The MFM Read Data lines are output lines driven by an RS-422 differential line driver. It is designed to drive a 105-ohm twisted pair or flat ribbon cable up to 20 feet long. These lines should be terminated by the host side of the standard RS-422 line receiver with 100-ohm input impedance. Multiple Drive Interconnect --------------------------- When more than one drive is installed into a host system, the cabling between the controller/data separator of the host system and the drive should be arranged.

All drive control input signals are unbalanced true-when-low signals, and are high impedance state when the drive is not selected. Drive Selected -------------- The Drive Selected line (on the data interface) is true whenever the Drive Selected line (on the control interface), matching the drive address, is true. Address Assignments ------------------- An individual drive may have an address of 0, 1, 2, or 3. The address is determinated by the connections of the drive select jumpers. A jumper installed at S1, S2, S3, or S4 will select drive address 0, 1, 2, or 3, respectively. Acoustic Levels --------------- Overall: 40 dbA Note: Measurements are taken in an anechoic chamber with the test unit suspended 1.0 meter (36 inches) from the floor (measured to the bottom of the drive with PCB facing down). To meet this specifica- tion, a one-half inch normal incident microphone should be centrally located one meter above the top surface of the drive and positioned perpendicular to the surface (diaphragm of the microphone to be parallel). Instrumentation should be capable of octave band overall "A" weighted readings within 0.5 db and dbA. ********************************************************************** F E A T U R E S ********************************************************************** KALOK OCTAGON KL320/330 OEM MANUAL 86001-001 REV.B General Description ------------------- The KL320/330 use a rotary band positioner driven by a bipolar stepper motor. This operates under the control of a microprocessor to position the read/write heads. The head positioning mechanism is designed in such a way that both thermal loops of the positioning system oppose each other. This results in an extremely accurate head positioning over the entire operating range. A ferrofludic seal is installed to eliminate contamination from the motor bearings. The recirculation filter at the periphery of the disks efficiently cleans the HDA air by trapping entrained particles. The electronics of the KL320/330 are mounted on a single circuit board beneath the HDA. On-board diagnostics monitor the power supply, host controller, and drive functions. Up to four OCTAGON KL 320/330 drives can be linked to a single controller on a common power and control bus. Access Time ----------- +----------------------------------+------+ |Track-to-Track msec. | 15 | +----------------------------------+------+ | Average msec. typ. | 48 | | Average msec. max. | 90 | +----------------------------------+------+ |Latency msec. avg. | 8.33 | +----------------------------------+------+ Buffered mode, including head settling time. Timing indicates average bidirectional seeks taken after last step pulse issued by the controller. All timing parameters are in buffered step mode. Precompensation --------------- For the KL320, precompensation is required on every track from cylinder 300 to 615. The optimum amount of precompensation is 12 nonoseconds for both early and late bits. Mapped Defects -------------- Each drive shipped from the factory will have a list of defects attached to the HDA cover. The list will indicate the number and location of hard errors. The defects must be execluded from any data or format usage in order to meet specified error rates. The maximum allowable defects are: a. 16 per drive b. 10 per disk surface All tracks on cylinder 0 will be error free. Note: Precompensation of write data must be used to meet the specified error rates and cylinder 0 must be defect free. Hard errors are defined as not recoverable within 16 retries. Soft errors are as recoverable at least once within 16 retries. Error rates specified are met in an unmarginalized state (open window - no strobe) and do not include the benefits of any error correction techniques which may be employed. Park Zone --------- For shipping and handling, seek to track 615. This will park the heads in a dedicated area away from data tracks. Otherwise, loss of data may occur. Reliability Specifications -------------------------- Mean time between failures (MTBF) 43,500 hours Mean time to repair 5 minutes Preventive maintenance required None Service life 6 years Drive Control and Power Interface --------------------------------- All drive outputs are driven by the tri-state drivers. All drive control output signals are unbalanced true when low, and are in the high-impedance state when the drive is not selected. Observe the following restrictions when applying power to the OCTAGON KL 320/330: a. If the 5-volt power is applied first, the 12-volt power must follow within 100 msec. Both the 5-volt and 12-volt power supplies must be able to maintain the necessary voltage and ripple specifications with 12-ohm resistive loads. b. During the first four sconds, the 12-volt supply must maintain these specifications with a 4.8-ohm resistive load. c. During operation, the voltage supplied to the drive must not exceed the specified tolerance 5%. Interface Signal Line Definition -------------------------------- The KL 320/330 interface contains two types of signals: unbalanced and differential. All unbalanced lines are true when low. For unbalanced inputs, the low level is 0 to 0.8 volts dc and the high level is 3.5 to 5.25 volts dc. For unbalanced output, the low level is 0.5 volts (max.) at +32mA, and the high level is 2.4 volts (min.) at -3 mA. The differential signals are standard EIA RS-422 signals. Termination is accomplished via a cut away 220/330 ohm resistor pack in SIP configuration (RN1) Power Up Sequence ----------------- When dc power is applied to the drive, it takes about five seconds for the drive to come to speed. READY, SEEK COMPLETE and SELECTED signals are typically displayed 12 seconds after power up.
