A, 1994 Jumper Setting ============== SS1 Spindle Synchronization ---------------------------- Jumper SS1 controls the spindle synchronization function. SS1 INSTALLED (factory default) The spindle synchronization signal is enabled onto pin 28 of Signal Connector J1. SS1 NOT INSTALLED The spindle synchronization signal is not enabled onto pin 28 of Signal Connector J1. ST1 Spindle Synchronization Signal ----------------------------------- ST1 INSTALLED The drive receives the spindle synchronization signal from pin 28 of Signal Connector J1. ST1 NOT INSTALLED (factory default) The drive emits the spindle synchronization signal onto pin 28 of Signal Connector J1. ID0/ID1 Master/Slave Selection ------------------------------- The interface allows up to two drives (a Master and one Slave) to be attached to the AT/IDE bus. +-----+------+------------------------------------+ | ID1 | ID0 |Description | +-----+------+------------------------------------+ | IN | IN |Drive emulates BOTH Master and Slave| +-----+------+------------------------------------+ | IN | OUT |Drive is Master, Slave is present | +-----+------+------------------------------------+ | OUT | IN |Drive is Slave | +-----+------+------------------------------------+ | OUT | OUT |Drive is Master | +-----+------+------------------------------------+ Drive emulates BOTH Master and Slave: ------------------------------------- Specifies that one drive can emulate BOTH the Master drive (Drive 0) and the Slave drive (Drive 1). This option allows for existing host systems to utilize the full capacity of the drive. When the drive is configured as BOTH the Master and the Slave, the following partition is implemented: Model 4110A Drive 0: 1024 cylinders, 16 heads, 63 sectors Drive 1: 1024 cylinders, 16 heads, 63 sectors Drive is Master, Slave is present: ---------------------------------- Specifies the Master drive (Drive 0) when two drives are used in a system. The other drive is Slave. Drive is Slave: --------------- Specifies the Slave drive (Drive 1) when two drives are used in a system. The other drive is Master. Drive is Master: ---------------- Specifies the Master drive (Drive 0) when one drive is used in a system. When the drive is configured as a Master or as a Slave, the re- commended drive type parameters are as follows: Model 4110A: 2048 cylinders, 16 heads, 63 sectors ********************************************************************** I N S T A L L ********************************************************************** MICROPL. 4110A PRODUCT DESCRIPTION 126162 REV. A Notes on Installation ===================== Dimensions and Mounting ----------------------- The drive uses industry-standard mounting for 3 1/2-inch, 1-inch high Winchester disk drives. Recommended orientation is vertical on either side, or horizontal with the Device Electronics board down; other mounting orientations may be used. horizontally vertically +-----------------+ +--+ +--+ | | | +-----+ +-----+ | | | | | | | | | +-+-----------------+-+ | | | | | | +---------------------+ | | | | | | | | | | | | | | | | | | | +-----+ +-----+ | +--+ +--+ 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. HDA Casting Temperature ----------------------- Micropolis specifies the maximum HDA casting temperature to be 65*C (149*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 -------------------- Signal Connector J1 is a 40-pin connector. The bus interface connection is made via this connector. Signals on J1 include the 16- bit data bus and control and address lines. Recommended Cable: 3M Scotchflex 3302-40 or equivalent Pins: AMP 350078-4 Suggested Wire Size: 18 AWG J1A Power Connector -------------------- Power is supplied to the drive via connector J1A (4-pin, keyed, AMP- MATE-N-LOCK).This power connector is the industry standard and is used in most applications. The recommended mating connector is AMP 1-480424-0 or equivalent; the recommended pins are AMP 350078-4, or equivalent. pin 1 +12 VDC pin 2 +12 Volts Return pin 3 + 5 Volts Return pin 4 + 5 VDC J1B Power Connector -------------------- J1B is a 3-pin, keyed connector. Both +5V and +12V are supplied to the drive via this connector. This power connector is usually used by low-power computer systems. The pin assignment in the following table differ from the pin assignments specified in the current ATA Specification in order to maintain compatibility with industry-standard conventions. The recommended mating connector is MOLEX 5480 or equivalent. pin 1 + 5 VDC pin 2 +12 VDC pin 3 Return Interface Electrical Characteristics ------------------------------------ Interface control, data, and status signals are TTL compatible in both send and receive directions. Maximum cable length is 18 inches. The following cable specifications are provided to ensure system integrity. Driver IOL sink current = 12 milliamps (minimum) Driver IOH source current is -400 microamps (maximum) Cable capacitive loading = 200 picofarads (maximum) ********************************************************************** F E A T U R E S ********************************************************************** MICROPL. 4110A PRODUCT DESCRIPTION 136162 REV. A, 1994 Some Features of the Drives --------------------------- - Digital Servo gives faster, more accurate positioning by adapting to dynamically changing environmental parameters - 30 to 47 MHz internal data transfer rate - highest performance AT/IDE drive available in the industry - Command Overhead less than 180 milliseconds - Supports emulation for both Master and Slave to allow usuage of existing DOS-to-BIOS communications - "Plug-and-play" compatibility with smaller capacity AT/IDE drives - Multiple Segment Read Look-Ahead operations for repetitive and sequential access - Multi-segment write caching - Extended command set includes Read Multiple and Write Multiple commands - EISA Demand Mode B DMA operation - LBA Mode - User can reassign bad sectors - User can flag bad sectors - Four bytes of ECC are transferred to host on Read Long and Write Long commands to maintain backward compatibility to existing designs - Power down command support Seek Time --------- +----------------------------------+--------+ | | 4110A | +----------------------------------+--------+ |Track-to-Track msec. typ. | 1.5 | +----------------------------------+--------+ |Average msec. typ. | 8.5 | | msec. max. | 20 | +----------------------------------+--------+ |Latency msec. avg. | 5.56 | +----------------------------------+--------+ Mechanical Assembly ------------------- The mechanical assembly consists of a sealed head/disk assembly (HDA). The HDA consists of a die-cast structure which contains virtually all of the drive's mechanical components. Two die-cast members create a sealed, clean area. Components included in the clean area are the servo head and data heads, magnetic disks, rotary positioner, and spindle. 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 drives require no adjustments or periodic maintenance; additionally, no mechanical adjustments are required to prepare a system for handling or shipment.
