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).
