A EC 10921 Jumper Setting ============== Switch Selectable Options ------------------------- Two optional features implemented via the drive select/option select dipswitch S1 are available for customer reconfiguration of drive functions. They are the Radial/Daisy Chain option and the PRIAM Unique Mode. Radial/Daisy Chain Option ------------------------- Switch S1-5 changes the drive select protocol. When S1-5 is OFF the drive interface is set for normal daisy chain operation. Switching S1-5 ON facilitates radial operation by forcing permanent drive selection regardless of the address chosen by drive select switches S1-1 through S1-4. PRIAM Unique Mode ----------------- Switch S1-6 selects recovery options from WRITE FAULT, and SERVO FAULT (loss of READY) conditions. The following protocol is established when PRIAM Unique is selected (closing S1-6): - When dc power is applied to the drive, sequencing up is no longer automatic. The drive will remain stopped with SEEK COMPLETE true and READY false. - Any motion command will cause the drive to sequence up. - SERVO FAULT and WRITE FAULT will both be reset when any motion command is received. Removal of dc power is not required to reset SERVO FAULT (loss of READY). Simple de-selection of the drive will clear WRITE FAULT but not SERVO FAULT. - The drive will not conceal seek faults by attempting three auto- matic retries. It will instead immediately post SEEK COMPLETE or NOT READY status. - When a forward illegal cylinder address greater than maximum is received, a sequence down will be executed. - As in the normal ST412 mode of operation, when a reverse illegal cylinder address less than zero is received, a fast restore to Cylinder 0 will be performed. Sequence Up/Down ---------------- In the normal ST412 mode of operation the drive will sequence up as soon as power is applied. However, the user may connect J13-12 with a jumper to an unused lin eof the J2 connector (such as J2-3) to provide a sequence up/down capability. The drive will spin down when the line is low, and it will spin up when the line is high. This line can be used to spin down the drive even in the PRIAM Unique Mode. J13-8/9 Write Protect ---------------------- Grounding J13-9 with a jumper to J13-8 will inhibit writing and protect all previously written data by causing WRITE FAULT if WRITE GATE is activated. J13 has sockets flush with the PCB on 0.1 in. centers and 0.3 in. spacing to accept low profile (<.20 in. high) DIP jumpers or wire jumpers.

If this done, WRITE FAULT can be cleared by de-selecting the drive, or by a momentary TTL low on the fault reset line J13-16, or by powering down the drive. +-------------------------------------+ |S1 Switch Settings | +-----------+---------------------+---+ |Position 1 |Drive Select 1 |ON | +-----------+---------------------+---+ |Position 2 |Drive Select 2 |ON | +-----------+---------------------+---+ |Position 3 |Drive Select 3 |ON | +-----------+---------------------+---+ |Position 4 |Drive Select 4 |ON | +-----------+---------------------+---+ |Position 5 |Radial Configuration |ON | +-----------+---------------------+---+ |Position 6 |PRIAM Unique |ON | +-----------+---------------------+---+ |Position 7 |UNUSED |-- | +-----------+---------------------+---+ |Position 8 |UNUSED |-- | +-----------+---------------------+---+ Drive Select Lines 1-4 ---------------------- When true, these lines enable their respective disk drive interfaces (maximum of 4).

These lines are not binary coded, and no two drives in a chain may have the same drive select switch on. ********************************************************************** I N S T A L L ********************************************************************** PRIAM 514/519 OEM MANUAL P/N 308086 REV. A EC 10921, 12/86 Notes on installation ===================== Required Mounting Orientation ----------------------------- Horizontal Spindle Impeller Down Vertical Power Connector J3 Up with Matrix PCBA Down (preferred, but either vertical orientation is acceptable) and Positioner Motion Horizontal within 5 degrees. Shipping Damage Inspection -------------------------- Priam disk drives are packaged to withstand normal handling in reusable shipping containers. It is the customer's responsibility to notify the carrier if shipping damage should occur to a drive. Note: When handling the drive while still in the shipping container, ensure that the container remains in the upright position indicated by the attached labels. Shock and Vibration Precautions ------------------------------- The drives must be handled in such a manner as not to exceed the Non- Operational Shock and Vibration limits. Introduction ------------ There are two flat ribbon cables used with the ST412 Interface. The larger one is a 34-pin edge connector, used to transfer all commands and most of the status information. It can be connected in either radial or daisy chain fashion. The second is a 20-pin edge connector, containing all the read/write data lines and one status line and must be connected in the radial configuration. Maximum 4 drives. Termination ----------- Every drive is shipped from PRIAM with a terminator installed to minimize reflections and ensure maximum data integrity. One terminator is required on each drive in a radial configuration. In a daisy chain configuration only the final drive needs one. (If the final drive in a daisy chain loses power or becomes inoperative, a terminator must be installed in the next to last drive.) J1/P1 Connector - Control Signals --------------------------------- Connection of J1 is through a 34-pin edge connector. The pins are numbered 1 through 34 with the even pins located on the component side of the PCB. Pin 2 is labeled. The recommended mating connector for P1 is AMP ribbon connector P/N 88373-3 or Molex 15-35-1341. All odd pins are ground. A key slot is placed between pins 4 and 6. J2/P2 Connector - Data Signals ------------------------------ Connection to J2 is through a 20-pin edge connector. The pins are numbered 1 through 20 with the even pins located on the component side of the PCB. The recommended mating connector for P2 is AMP ribbon connector P/N 88373-6, or Molex P/N 15-35-1201. A key slot is placed between pins 4 and 6. J3/P3 Connector - Power ----------------------- DC power connector (J3) is a 4-pin AMP Mate-N-Lok connector P/N 350211-1 mounted on the component side of the Servo PCBA. The recommended mating connector is AMP P/N 1-480424-0 utilizing AMP pins P/N 61314-4 (Strip) or P/N 60617-4 (Loose piece). pin 1 +12 VDC | pin 2 +12 V RETURN | pin 3 + 5 V RETURN ----+ +-------+ | pin 4 + 5 VDC | |1 2 3 4| | | \-------/ | +-----------+ J14/P14 Frame Ground Connector ------------------------------- Faston AMP P/N 61761-2 Recommended mating connector AMP 62187-1 If used, the hole in J14 will accomodate a wire of size 18AWG max. Data Transfer Lines ------------------- All lines associated with the transfer of data between the drive and the host system are differential in nature and may not be multi- plexed. These lines are provided at the J2/P2 connectors on all drives. Two pairs of balanced signals are used for the transfer of data: WRITE DATA and READ DATA. Flat ribbon or twisted pair Maximum 20 feet Note: Any EIA RS 422 Driver/Receiver pair will interface. ********************************************************************** F E A T U R E S ********************************************************************** PRIAM 514/519 OEM MANUAL P/N 308086 REV. A EC 10921, 12/86 General Information ------------------- PRIAM 5.25-inch disk drives use advanced Winchester and micro- processor technologies to provide users with low-cost disk drives having high capacity, fast access, and long-term reliability. A linear voice coil positioner with track following servo enables the PRIAM 5.25-inch drives to position mini-Winchester type heads quickly and precisely. These low-force heads promote high data reliability. Advanced 5.25-inch, carbon overcoated, thin film, Winchester technology disks are driven by a brushless dc motor. The heads, disks, and head positioner coil and carriage are enclosed in a sealed, contamination-resistant chamber to ensure high data reliability. Media Defects ------------- A media defect is some physical characteristic of the media which results in a repetitive read error when the drive is operating within specified operating conditions. Valid data must not be written over known media defects. All drives are chipped with a defect map, listing the following information: - Cylinder - Head - Defect Location - Defect Length (in bits) The defect location is specified in bytes ( 10 bytes) from the leading edge of index. The maximum number of defects allowed at the time of initial shipment is as follows: 514 519 - Defects per Drive (max allowed) 140 191 - Defects per Surface (max allowed) 25 25 There will be zero defects on track zero, heads 0-7 inclusive, at the time of initial shipment. Air Filtration Components ------------------------- A self-contained recirculating filter supplies clean air through a 0.3 micron filter to the sealed HDA. A separate filter allows for ambient atmospheric pressure equalization within the assembly without the induction of contaminants.
