 Jumper Setting
 ==============

 x = Jumpers set at factory


 On both PCB's Jumpers JP41, JP43, JP21 and on PCB with a SHROUDED
 CONNECTOR, JP91 through JP94  are for Manufature Test purposes, they
 are NOT USER SELECTABLE and are shipped CLOSED.



 JP42  Write Protect
 -------------------
     CLOSED   Data cannot be written to the drive, only read opera-
              tions can be executed.
  x  OPEN     Allowing normal reading and writing.

 Located very close to the J2 power connector and the corner of the
 PCB, the write protect jumper is used to protect the data written to
 the XT-3000.


 JP44  Spin On Power-Up
 ----------------------
     CLOSED  The motor will start as soon as power is applied.
             DRive will spin down when power is removed from drive.

 On 3170/3280 OCB with a NON-SHROUDED connector, this jumper must be
 installed all times.

 On 3170/3280 PCB with a SHROUDED connector, this jumper, when
 installed, overrides the position of JP87. On this PCB part number
 it is recommended that JP44 is installed, that JP87 also be
 installed.


 JP81/JP82  Terminator Power
 ---------------------------
   JP81  OPEN
   JP82  CLOSED
   The terminator power is external from the SCSI bus.

   JP81  CLOSED
   JP82  OPEN
 x The terminator power is internal from the drive.


 JP83/84/85  SCSI ID
 -------------------
            +----------+-----------------------+
            | SCSI ID  |        Jumpers        |
            |          | JP85  | JP84  | JP83  |
            +----------+-------+-------+-------+
 Lowest-----|x --0     | OPEN  | OPEN  | OPEN  |
            |    1     | OPEN  | OPEN  | CLOSED|
            |    2     | OPEN  | CLOSED| OPEN  |
            |    3     | OPEN  | CLOSED| CLOSED|
            |    4     | CLOSED| OPEN  | OPEN  |
            |    5     | CLOSED| OPEN  | CLOSED|
            |    6     | CLOSED| CLOSED| OPEN  |
 Highest----|----7     | CLOSED| CLOSED| CLOSED|
 Priority   +----------+-------+-------+-------+

 As shipped from the factory, all jumpers are open, giving the XT-3000
 a priority value/ID of zero.

 In multiple SCSI device configuration, it is necessary to configure
 each device with a priority. The priority identification for each
 drive is determined by the three binarily weighted ID jumpers. An ID
 of 7 is the highest priority in a multidevice configuration.


 JP86  SCSI bus parity
 ---------------------
 x JP86  CLOSED  Enables odd parity detection.
         OPEN    Disables odd parity detection.

 As shipped from the factory the XT-3000 detects parity. Odd parity is
 always generated.


 JP87  DRIVE TYPE/SPIN DELAY/START COMMAND
 -----------------------------------------
 On PCB with a NON-SHROUDED connector, JP87 is the DRIVE TYPE jumper.
 On PCB with a SHROUDED connector, JP87 is the SPIN DELAY/START
 COMMAND jumper. The SPIN DELAY/START COMMAND functions do not exist
 on PCB with a NON-SHROUDED connector. There is no DRIVE TYPE jumper
 on PCB with a SHROUDED connector.


 JP87  PCB with a NON-SHROUDED Connector  Drive Type
 ----------------------------------------------------
   JP87  CLOSED  The drive reports its type as an XT-3170 (170MB) in
                 the INQUIRY command.
         OPEN    The drive reports its type as an XT-3280 (280MB).


 JP87  PCB with a SHROUDED Connector Spin Delay/Start Command
 -------------------------------------------------------------
    JP87  CLOSED  The ID value will be used to facilitate a sequential
                  drive power-up process. The spindle motor turn-on,
                  after power-up, is delayed by approximately 13
                  seconds for each prioity ID level.
          OPEN    The drive will not spin-up until the Host issues a
                  Start/Stop Command (1Bh) with the Start Bit = 1.

 In order for the JP87 options to operate on this PCB, JP44 MUST be
 removed.

MAXTOR   XT-3000  OEM MANUAL 1011005 REV. C

 Interface Termination
 ---------------------
 As shipped, all assigned interface signal lines are terminated with a
 removable 220/330 ohm resistor network. The first device and the last
 device on the daisy-chain SCSI bus must be terminated. Remove the
 terminators from any devices in between. For instance, if the XT-3000
 is in the middle of the string, remove its terminators. Any host
 adapters beeing used should be terminated in a similar fashion.

 The devices driving the drive inpute should be open collector devices
 capable of sinking at least 48 milliamps at a voltage level of less
 than 0.5 VDC (7438 or equivalent).

 Devices receiving the drive outputs should be of "SCHMITT" trigger
 type to improve noise immunity, 74LS14, 74LS240 or equivalent. The
 host adapter should not load the bus with more than one standard
 LSTTL input load per line, and should terminate the drive output
 signals with 220/330 ohm terminators.
