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 W12

  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 W12, 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.

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

  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 W12 and W13 provide termination for the Spindle
  Synchronization signals (Slave Sync and Master Sync respectively).

  When Spindle Synchronization is to be implemented, jumpers W12 and W13
  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.
