W2 CLOSED Host system provides terminator power (via J1 pin 26) to RN1 and RN2. W3 CLOSED Drive provides terminatpr power (via J1, pin 26) to the BUS. W10/W11 Spindle Sync Termination --------------------------------- Spindle Sync Termination depends on system configuration; i.e., Master Mode or Master Control Mode. W10 and W11 INSTALLED (default) Slave Sync (W10) and Master Sync (W11) are terminated. W10 and W11 OPEN Spindle sync is not terminated. Spindle Synchronization ----------------------- The Rotational Position Locking field (MODE SELECT command, Page Code 04h) is used to specify spindle synchronization operation. NOTE that SSYNC = slave sync and MSYNC = master sync Unsynchronized: If the drive is set to Unsynchronized (RPL = 00b), it ignores the SSYNC signal. Slave: If the drive is set to Slave (RPL = 01b), it does not generate the MSYNC signal or the SSYNC signal but synchronizes its index to the SSYNC signal supplied by an external source. Signal termination is placed on the SSYNC signal at the first and the last device in the chain only. Master: If the drive is set to Master (RPL = 10b), it generates the SSYNC output signal for use directly by the slave drives. Signal termination is placed on the SSYNC signal at the first and the last device in the chain only. Master Control: If the drive is set to Master Control (RPL = 11b), it generates the MSYNC signal. This output is used by the controller to generate the SSYNC signal for the slaves. Signal termination is placed on the MSYNC signal at the first and the last device in the chain only. Signal termination is placed on the SSYNC signal at the first and the last device in the chain only. ********************************************************************** I N S T A L L ********************************************************************** MICROPL. 4110 PRODUCT DESCRIPTION 136161 REV. A, NOV. 1993 Notes on Installation ===================== Dimensions and Mounting ----------------------- The drives use industry-standard mounting for 3 1/2-inch, 1-inch high, Winchester disk drives. Drive mounting -------------- horizontally vertically +-----------------+ +--+ +--+ | | | +-----+ +-----+ | | | | | | | | | +-+-----------------+-+ | | | | | | +---------------------+ | | | | | | | | | | | | | | | | | | | +-----+ +-----+ | +--+ +--+ Recommended orientation is vertical on either side, or horizontal with the Device Electronics board down; other mounting orientations may be used. No matter what mounting orientation is used, Micropolis specifies that the maximum HDA casting temperature not exceed 60*C (140*F). CAUTION The mounting screws must be selected so that they do not penetrate the bottom mounting holes by more than 0.20 inches or the side mounting holes by more than 0.156 inches. Screws that are too long may short to PCBA components. Mounting Holes: 3 per side, 4 on bottom, 6-32 UNC-2B Temperature Measurement ----------------------- Micropolis specifies the maximum HDA casting temperature to be 60*C (140*F). Not exceeding this temperature will ensure that head-to- media interface never exceeds its temperature limit. If the HDA casting temperature measurement cannot be made, the ambient air temperature around the drive must be kept at or below 50*C (122*F). J1 Signal Connector ------------------- J1 is 50-pin interface connector. The signals on J1 include the 8-bit SCSI bus and various control and handshaking lines. Recommended Cable: 3M Scotchflex 3365/50 or equivalent Mating connector: 3M P/N 3425-3000 or equivalent J1A Power Connector ------------------- J1A is a 4-pin connector used to supply +5V and +12V to the drive. Recommended mating connector: AMP 1-480424-0 or equivalent Pins: AMP 350078-4 Suggested wire size: 18 AWG (minimum) for all pins. pin 1 +12 VDC pin 2 +12 Volts Return pin 3 + 5 Volts Return pin 4 + 5 VDC Spindle Synchronization Connectors (2-pin) ------------------------------------------ Recommended mating connectors: Dupont 69305-002 or equivalent Pins: Dupont 77138-001 Suggested wire size: 26-30 AWG for all pins Remote LED Connector (2-pin) ---------------------------- Recommended mating connector: Dupont 69305-002 or equivalent Pins: Dupont 77138-001 Suggested wire size: 26-30 AWG for all pins Remote SCSI ID Connector (6-pin) -------------------------------- Recommended mating connector: Dupont 90311-006 or equivalent Pins: Dupont 77138-001 Suggested wire size: 26-30 AWG for all pins Remote Option Connector (24-pin) -------------------------------- Recommended mating connector: Dupont 90311-024 or equivalent Pins: Dupont 77138-001 Suggested wire size: 26-30 AWG for all pins Interface Electrical Characteristics ------------------------------------ Interface control and status signals are digital (open collector TTL) using industry-standard transmitters and receivers which provide a terminated, single-ended system. For active termination, the assigned signals are terminated with 110 ohms to +2.85V (nominal). For passive termination, the assigned signals are terminated with 220 ohms to +5V (nominal) and 330 ohms to ground. All signals use open-collector or tri-state drivers. Single-ended drivers and receivers allow a maximum cable length of six meters (primarily for connection within a cabinet). Signal transmission requires a single 50-conductor (flat or twisted pair) cable. A characteristic impedance of 100 ( 10%) ohms is recommended. a. Input Characteristics Each of the drive's signal receivers has the following characteristics when measured at the interface connector. 1) Low-level input voltage (Signal true) = 0.0 VDC to 0.8 VDC 2) High-level input voltage (Signal false) = 2.0 VDC to 5.25 VDC 3) Low-level input current = -0.4 milliamps at 0.5 VDC 4) High-level input current = 0.1 milliamps at 2.7 VDC 5) Minimum input hysteresis = 0.2 VDC 6) Maximum input capacitance = 25 pF b. Output Characteristics Each of the drive's signal drivers has the following characteristics when measured at the interface connector. 1) Low-level input voltage (Signal assertion) = 0.0 VDC to 0.5 VDC 2) High-level input voltage (Signal negation) = 2.5 VDC to 5.25 VDC 3) Minimum driver output capability = 48 milliamps (sinking) at 0.5 VDC. c. Terminator Power (TERMPWR at Pin 26) Terminator Power has the following requirements: V(TERM) = 4.25 VDC to 5.25 VDC 800 milliamps minimum source drive capability, with 1.0 amp recommended current limiting (e.g., a fuse). 1.0-milliamp maximum bus loading (except for the purposes of providing power to an internal terminator). The drive provides keyed connectors to prevent accidental grounding or misconnection of terminator power.

A, NOV. 1993 DIFFERENTIAL INTERFACE IS OPTIONAL. Some Features of the Drive -------------------------- - Positive media protection is achieved during spin down (due to a STOP UNIT command or power off) by automatically retracting and locking the positioner in a data-free landing zone. - N-Segment Read-Ahead algorithm improves read performance by allowing many accesses to be serviced from the 512K cache buffer. - Write-Behind Caching, when implemented, provides dramatic improvement in write performance by appending multiple write commands per disk revolution. - In-Line Defect Management (sector slipping) provides maximum throughput. - Data Integrity is ensured with interface parity through the buffer, automatic retries using servo and data strobe offsets, and a 126- bit Reed-Solomon ECC on-the-fly. - Optional Set Capacity function allows easy matching of block number counts for upgrades and emulations. Media Defects ------------- Media defects are physical characteristics of the media which result in repetitive read errors when a functional drive is operated within specified operating conditions. At the time of manufacture, a media test system evaluates every drive and identifies each media defect location. The defective areas are identified by head address (HD), cylinder address (CYL), and number of bytes from Index (BFI). The list of manufacturer-found defects is stored on the drive in a reserved, write-protected area accessible by the SCSI controller. This list is known as the MDL (Manufacturers Defect List) or PList (Primary Defect List). A printed listing of the defects is also shipped with each drive. The entries it contains can be mapped out (reassigned) automatically at format control parameter bits.

The recording surface on each disk is a thin coating of magnetic material, with a carbon over-coat to protect it. Air Filtration System --------------------- The drives are designed to provide contamination control within the HDA throughout the life of the drive with zero maintenance. Air within the HDA is continuously recirculated and filtered through a high efficiency filter. A breather filter protects the HDA from inward contamination migration during air pressure changes associated with drive temperature or atmospheric pressure variations. Adjustments and Maintenance --------------------------- The drive requires no adjustments or periodic maintenance; additionally, no mechanical adjustments are required to prepare a system for handling or shipment. MICROPOLIS AV SERIES -------------------- Micropolis AV Series disk drives are engineered specifically for multi-media, high-end graphics, and digital video/audio applications. With advanced cache management, internal housekeeping improvements, and enhanced error handling, AV drives provide the highest minimum sustained data rate in their class. AV drives are designed to provide a maximum sustained uninterrupted data rate. Unlike data processing drives, AV drives guarantee a "worst case" data rate performance. This means that with the buffer empty, the maximum access time (including error handling) is no more than 30 milliseconds. The Micropolis 4110AV drive ensures highly predictable data delivery, so you will never miss a frame or a beat.
