JP3 is the park feature enable, it must be installed to use the 30 second park feature. Terminators ----------- Each drive is shipped with a terminator pack providing the 220/330 ohm termination for the Control Input Signals. If multiple drives are configured in a daisy chain configuration, the terminator pack must be removed from all drives except the last unit on the daisy chain. ********************************************************************** I N S T A L L ********************************************************************** MINISC. 3650 PRODUCT MANUAL 1076, REV.

Recommended Mounting Configuration ---------------------------------- The MiniScribe 3650 half height 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. Two features which allow greater shock tolerances are the use of rugged media and shock mounts. To take full advantage of the shock mounts, however, it is necessary to provide a 0.1 inch clearance on both the top and bottom of the drive. This clearance allows for move- ment of the drive during acceleration. This implies that if the drive is mounted by the bottom mounting holes on a flat surface, stands-off are needed under the mounting holes. No special considerations are required if the drive is mounted using the side mounts except for the clearance on top and bottom. The drive may be mounted in any attitude except upside down. The drive is mounted using 6-32 UNC screws, 1/4 inch maximum penetration. The customer should allow adequate ventilation to the drive to insure reliable drive operation over the operating temperature range. Cabling ------- Connect interface cables with connectors P1, P2, P3, and P4 to J1, J2, J3, and J4 respetively. Insure that connectors P1 and P2 have keys installed. If multiple drives are be interconnected, remove the terminator packs in all but the last drive in the daisy chain. Magnetic Field -------------- The externally induced magnetic flux density may not exceed 3 Gauss as measured at the disk surface. Electrical Interface -------------------- The interface to the MiniScribe 3650 can be divided into three categories, each of which are physically separated: Comtrol Signals, Data Signals and DC Power. All Control Signals are digital in nature (open collector TTL) and either provide signals to the drive (input) or signals to the controller (output). The Data Signals are differential in nature and provide data either to (write) or from (read) the drive. The interconnect cable between the drive and controller may be flat ribbon or twisted pairs of a length not to exceed 20 feet. The signal return lines and ground lines for P1 and P2 should be grounded at the controller. The voltage return lines of P3 should only be grounded at the power supply. Connector P4 is a spade lug connector tied to frame ground.

Caution/Warning --------------- The Miniscribe drive is a precision product weighing 3.5 pounds. During handling the unit must not be dropped, jarred or bumped. Otherwise, damage to the heads and disks may occur. When the drive is removed from the Miniscribe shipping container and not immediately secured within a chassis through its shock mounts, it must be stored on a soft padded surface. Failure to comply with the above procedure will render null and void all warranties. ********************************************************************** F E A T U R E S ********************************************************************** MINISC. 3650 PRODUCT MANUAL 1076 REV. A, APRIL 7, 1987 Introduction ------------ The MiniScribe 3650 is a half-height reandom access 5-1/4 inch rigid media disk drive employing Winchester technology. The drive utilizes a rack-and-pinion actuator, microprocessor control, and open loop stepper head positioning. The Model 3650 features power up diagnostics, buffered seek and 5 Megabit/Sec. transfer rate. D.C. voltages and physical form factor are the same as the 5-1/4 inch half height floppy disk drive.

Additionally, some operations are monitored during normal operations. If an error is detected, the microprocessor will flash a warning by blinking the activity LED. Error codes may be generated by the microprocessor to indicate hard- ware failures or warnings that are detected during power-on diagnostics, burn-in mode, or normal operation. Error codes are diaplayed in a "morse-code" type manner. Bits may be interpreted and converted into hexadecimal error codes. "Zeros" are indicated by a short (1/2 second) flashingn mode. "Ones" are indicated by a short (1/2 second) continuous ON mode. Error "Words" are separated by a one second LED off time. Zero = 0.5 second flashing mode One = 0.5 second continuous ON mode Between Bits = 0.5 second Off Between Repeat Cycles = 1.0 second Off Listed Below are the binary to hexadecimal conversion values: 0 = 0000 4 = 0100 8 = 1000 C = 1100 1 = 0001 5 = 0101 9 = 1001 D = 1101 2 = 0010 6 = 0110 A = 1010 E = 1110 3 = 0011 7 = 0111 B = 1011 F = 1111 Message Definitions ------------------- Code 0 - Microprocessor RAM error Code 1 - Microprocessor ROM checksum error Code 2 - Interface chip diagnostic failure Code 3 - Write Fault latch will not reset Code 4 - Index pulse not detected during spinup Code 5 - Unable to reach 3600 rpm in 30 seconds Code 6 - Unable to stabilize spin speed in 10 seconds Code 7 - Unable to maintain spin speed to 0.5% Code 8 - Unable to uncover Track Zero sensor Code 9 - Unable to cover Track Zero sensor Code A - Track Zero interrupter misadjusted Code B - Shipping zone error, crash stop misadjusted Code C - Carriage stuck during recal error Code D - Seek errror during burn-in or recal Code E - Unused Code F - Unexpected interrupt from processor Formatting Guidelines --------------------- Before a hard disk drive can be used, 3 steps must be completed: 1. The drive must be low-level formatted to establish communications with the disk drive and controller board. 2. The drive must be partitioned into one or more logical drives. Use the fdisk programm from DOS versions 3.3 or higher or partioning software like Disk Manager or Speedstor. 3. The drive must be high-level formatted to prepare it for the operating system installation. Use the DOS format command or Disk Manager/Speedstor software. XT 8086/8088 Installation ------------------------- Use the utilities from any 8 bit controller board to low-lwvel format the drive. Typical routinetis to use the DOS debug command to address these utilities. If the low-level format program of the controller asks for step pulse rate or control byte values, use the controller default values. AT 80286/80386 Installation --------------------------- Use the MiniScribe version of Ontrack Disk Manager software or the Universal version of Speedstor software of the entire formatting process.
