 Single-Ended Configuration Options
 ----------------------------------

 SCSI ID
 -------
 NOTE:
 There are two identical groups of address jumpers on the Device
 Electronics board; use either group for address selection but not
 both at the same time.

   +----------+-----------------------+ Up to eight devices (the host
   | SCSI ID  |        Jumpers        | and seven targets) can be
   |          | ID2   | ID1   | ID0   | attached to the SCSI Bus.
   +----------+-------+-------+-------+
   |    0     | OPEN  | OPEN  | OPEN  | ID jumpers ID0, ID1 and ID2
   |    1     | OPEN  | OPEN  | CLOSED| are used to assign one of
   |    2     | OPEN  | CLOSED| OPEN  | eight SCSI ID bits (0-7) to
   |    3     | OPEN  | CLOSED| CLOSED| the drive.
   |    4     | CLOSED| OPEN  | OPEN  |
   |    5     | CLOSED| OPEN  | CLOSED| In multiple-device systems,
   |    6     | CLOSED| CLOSED| OPEN  | each drive must have its own
   | x  7     | CLOSED| CLOSED| CLOSED| unique ID.
   +----------+-------+-------+-------+


 Interface Termination
 ---------------------
 Terminators installed at RN1 and RN2 (default)
 Drive provides termination for the interface lines.

 Terminators at RN1 and RN2 omitted
 Drive does not provide termination for the interface lines.


 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
 --------------------------------------
     +-----+  +-----+  +-----+
    W3 xxx |  | o X W2 | o o |
     | o o |  | o X |  | xxx W1
     +-----+  +-----+  +-----+

 W1  CLOSED (default)
     Drive provides local terminator power.

 W2  CLOSED
     Host system provides local terminator power.

 W1  CLOSED and W3 CLOSED
     Drive provides terminator local power and terminator power to the
     bus.


 Remote LED Option
 -----------------
 LED (user supplied) connected to Remote LED
 Both LEDs (on Device Electronics board and remote location) are
 enabled.

 Remote LED not connected (default)
 LED on Device Electronics board enabled.


 Spindle Synchronization
 -----------------------
 The Rotational Position Locking field (MODE SELECT command, Page Code
 04h) is used to specify spindle synchronization operation.

 Unsynchronized: If the drive is set to Unsynchronized (RPL = 00b), it
 ignores the SLAVE SYNC signal.

 Slave: If the drive is set to Slave (RPL = 01b), it does not generate
 the MASTER SYNC signal or the SLAVE SYNC signal but synchronizes its
 index to the SLAVE SYNC signal supplied by an external source. Signal
 termination is placed on the SLAVE SYNC 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
 SLAVE SYNC output signal for use directly by the slave drives. Signal
 termination is placed on the SLAVE SYNC 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 MASTER SYNC signal. This output is used by the
 controller to generate the SLAVE SYNC signal for the slaves. Signal
 termination is placed on the SLAVE SYNC signal at the first and the
 last device in the chain only.
