ID0, ID1, ID2 SCSI Address Jumpers
  The SCSI ID (drive address) jumpers are identified as ID0, ID1, 
  and ID2. ID selection is binary, as shown in the table below.
SCSI
Address
Jumpers
ID2 ID1 ID0
0 out out out
1 out out in
2 out in out
3 out in in
4 in out out
5 in out in
6 in in out
7 in in in
  For multiple drive installations, on one Host Adapter, each drive 
  must have a unique address. Drives are configured as SCSI ID 7 
  at the factory.  
 
RN1, RN2, (RN3) Interface Terminator  
  The Interface Terminator factory installed at RN1, RN2, and RN3 
  provides proper termination for the interface lines. When 
  daisy-chaining multiple drives, leave the terminators installed 
  only in the last physical drive (or drives) on the daisy chain 
  cable; remove all three terminators from each of the other drives 
  (or the host computer). Note that there is no RN3 jumper on the 
  revision 2 board.
 
Bus Termination Power Option  
  A jumper is installed at W1, at W2, or at W2 and W3 to select the   
  source of terminator power (+5V) for the SCSI Bus terminator packs on 
  the device electronics board.

  DO NOT INSTALL JUMPERS AT BOTH W1 AND W3

  When a jumper is installed at W1 (the factory default configuration), 
  the drive provides terminator power to it's on-board terminators.

  When  a jumper is installed at W2 , terminator power is is provided by 
  the host system via the interface cable J1, pin 26 (TERMPWR).

  When a jumper is installed at both W2 and W3, the drive provides     
  terminator power to its on-board terminators and also to the SCSI bus 
  via interface cable J1, pin 26 (TERMPWR).

Spindle Control Option
  A jumper at SPIN0 is used to select the spindle control option.

  When a jumper is installed, the drive must wait for an interface 
  START UNIT command to start the spindle motor.

  When a jumper is NOT installed, (the factory default configuration),
  the drive automatically starts the spindle motor at power-on.

Spindle Delay Option
  A jumper at SPIN1 is used to select the spindle delay option 
  (spindle start-up is delayed based upon the SCSI ID). Delay time
  per ID is 12 seconds.

  NOTE: Do NOT install jumpers at both SPIN0 and SPIN1.

  When a jumper is installed, spindle delay is enabled.
 
  When a jumper is NOT installed, (the factory default configuration),
  spindle delay is disabled.

Bus Parity Option
  A jumper at PARITY is used to select parity check option.

  When a jumper is installed (the factory default configuration), the drive 
  generates but does not detect parity.

  When a jumper is not installed, the drive generates parity and enables 
  parity detection.

SCSI-1/2 Select
  A jumper at WP selects SCSI-1 or SCSI-2. If the jumper is installed (the
  factory default configuration), the drive is configured as a SCSI-2 device.
  the drive is not write protected.

LED Option Selection
  A jumper at W4 is used to select the front bezel LED option
  
  When a jumper is installed (the factory default configuration), 
  the front bezel LED is enabled.

  When a jumper is not installed, the front bezel LED is disabled.
  
Spindle Synchronization Option
  Jumpers installed at W10 and W11 provide termination for the Spindle
  Synchronization signals (Slave Sync and Master Sync respectively).

  When Spindle Synchronization is to be implemented, jumpers W10 and W11
  are removed from all drives except the last drive on the cable.

  The Rotational Position Locking field (MODE SELECT command, Page Code 04h) 
  is used to specify spindle synchronization operation; see document #110366 
  (Scsi Implementation in Micropolis "MZR" Products) and ANSI-2 SCSI Standard.

  Unsynchronized:  If the drive is set to Unsynchronized (PRL=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 (J2, pin 20) supplied by an external   
  source.

  Master:  If the drive is set to MASTER (RPL=10b), it generates the SLAVE 
  SYNC output signal (j2, pin 20) for use directly by the slave drives.

  Master Control:  If the drive is set to Master Control (RPL=11b), it     
  generates the MASTER SYNC signal (j2, pin 20). This output 
  is used by the controller to generate the SLAVE SYNC 
  signal (J2, pin 20) for the  slave drives.
