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

 x = Jumpers set at factory


 Jumpers JP1, JP2, JP3, JP4, JP5, JP6, JP9, JP88, JP89, JP90, JP91 are
 for Manufature Test ONLY, they are NOT USER SELECTABLE and are
 shipped CLOSED.

 JP7:              Write Protect
 JP8:              Immediate Motor Spin Up Option
 JP10, JP11:       Terminator Power Selection
 JP12, JP13, JP14: SCSI Controller ID
 JP15:             Parity Enable
 JP16:             Power On Spindle delay Option

 E1: Adjacent pin E1 is a ground point

 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.


 JP7  Write Protect
 ------------------
     CLOSED   Data cannot be written to the drive, only read opera-
              tions can be executed.
  x  OPEN     Allowing normal reading and writing.


 JP8/JP16  Spin On Power/Delay/Command
 -------------------------------------
   JP8  OPEN
   JP16 OPEN
   With both jumpers removed (OPEN) the drive will not spin-up until
   the Host issues a Start/Stop command (1BH) with the Start Bit = 1.

   JP8  OPEN
   JP16 CLOSED
   With JP8 removed (OPEN) and JP16 installed (CLOSED), the drive
   spins-up after exhausting a 13 second per SCSI ID delay.

   JP8  CLOSED
   JP16 OPEN
   With JP8 installed (CLOSED) and JP16 removed (OPEN), the drives
   spins-up immediately when power is applied.


 JP10/JP11  Terminator Power
 ---------------------------
   JP10  OPEN
   JP11  CLOSED
   The terminator power is external from the SCSI bus.

   JP10  CLOSED
   JP11  OPEN
 x The terminator power is internal from the drive.


 JP15  SCSI bus parity
 ---------------------
 x JP15  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.

 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.
