 NOTE
 Pin 4, 6, 8, 10, 12, 14, 16, 18 and 26 are tied to Ground.

 Option Jumper Block J2 is a 28-pin connector used for drive
 addressing and various configuration options.

 Test Connector is for factory use only - no jumper connections
 allowed.

 Up to eight devices (the host and seven targets) can be attached to
 the SCSI Bus. ID jumpers ID0, ID1 and ID2 are used to assign one of
 eight SCSI ID bits (0-7) to the drive.

 In multiple-device systems, each drive must have its own
 unique ID.


 SP0/SP1  Spindle Control Option
 -------------------------------
    SP0 CLOSED
    SP1 OPEN   Spindle motor starts when START UNIT command is
               received.

    SP0 OPEN   (default)
    SP1 OPEN   Spindle motor starts at power-on.


 SP0/SP1  Spindle Delay Option
 -----------------------------
    SP1 CLOSED
    SP0 OPEN   Spindle start-up is delayed based on SCSI ID (12
               seconds per ID).

    SP1 OPEN   (default)
    SP0 OPEN   Spindle motor starts at power on.


 WP  Write Protect Option
 ------------------------
    WP CLOSED  Drive is write protected.
    WP OPEN    Drive is not write protected. (default)


 PTY  Bus Parity Check Option
 ----------------------------
    PTY CLOSED  Drive neither generates nor detects parity.
        OPEN    Drive generates parity and has parity detection
                enabled. (default)


 W1/W2/W3  Bus Termination Power Option
 --------------------------------------

 W1  CLOSED (default)
     Drive provides local terminator power.

 W2  CLOSED
     Host system provides local terminator power (via J1).

 W3  CLOSED
     Drive provides terminator power (via J1) to the SCSI BUS.


 W4 Interface Termination
 ------------------------
   W4 *INSTALLED  Drive provides termination for the interface lines,
                  i.e., onboard termination is electrically enabled.

       OMITTED    Drive does not provide termination for the interface
                  lines; i.e., onboard termination is electrically
                  disabled.

 Remote LED
 ----------
 User-supplied LED connected to Remote LED: anode connected to J2 pin
 1; cathode connected to J2 pin 2.
 => Both LEDs (on Drive and remote location) are enabled.

 LED not connected (default) => LED on Drive is enabled.

 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.

 The 4743NS drive uses industry-standard mounting for 3.5-inch, 1-inch
 high, disk drives.

 Recommended orientation is vertical on either side, or horizontal
 with the Device Electronics board down; other mounting orientations
 may be used.

 No matter what the mounting orientation is used, Micropolis specifies
 the maximum allowable HDA casting temperatur to be 60*C (140*F).
