 When pin seven is connected to ground, the drive is protected from
 writing, regardless of commands sent to the drive via the SCSI inter-
 face. The write protect signal may also be connected to an LED whose
 (+) terminal is tied to a voltage source, so that the LED is
 illuminated when the pin is grounded and the drive is in write
 protect mode.

 For remote write protect, JP18 must be removed.

 When an LED is connected to pins one (+) and five (-), that LED
 functions in the same manner as the LED which is mounted on the
 drive's faceplate. This is typically used in cases when the drive
 is positioned where the LED is not visible or the faceplate has been
 removed.

 Pin three is not present so that users can key the mating connector.
 Pin three of the mating connector should be blocked for this purpose.

 The SCSI ID of the drive may be programmed remotely by selectively
 connecting pins six (ID2), eight (ID1), and ten (ID0) to ground, or
 leaving them open.

 SCSI ID jumpers (JP35 through JP37) must be removed for the remote
 SCSI ID option.

 The drive is shipped from the factory with an ID of six. This assures
 that sufficient jumpers are available for any address except seven,
 which is usually reserved for the host system.

 The SCSI device ID can also be set remotely through the auxiliary
 connector. The SCSI ID jumpers must be removed for this option. Any
 shorting required for a selected ID is done outside the drive.


 JP14/JP38  Drive Power-Up Options
 ---------------------------------
 In order to allow for system power supply constraints, which may
 require minimizing surge current when powering up multiple drives,
 three modes of start up sequencing are provided.

   +------+--------------+-----------------------------+
   |JP14  |JP38          |Mode                         |
   +------+--------------+-----------------------------+
   |OPEN  |OPEN          |Start by ID Sequence         |
   +------+--------------+-----------------------------+
   |OPEN  |CLOSED        |Wait for START Command       |
   +------+--------------+-----------------------------+
  x|CLOSED|OPEN or CLOSED|Start when power is Applied  |
   +------+--------------+-----------------------------+

 JP14 = Spin with power
 JP38 = Spin delay

 Start by ID Sequence
 With both JP14 and JP38 out, the drive delays spinup for approxi-
 mately 11 to 13 seconds times the SCSI ID. This allows for power up
 sequencing. A RESET condition results in the drive delaying its
 spinup according to its SCSI ID.

 Wait for Start Command
 With JP14 out and JP38 in, the drive does not spin up until the
 initiator issues a START/STOP UNIT Command with the start bit equal
 one.

 Start when power is Applied
 When JP14 is in and JP38 is out, the motor starts as soon as power is
 applied. The drive is shipped in this configuration.

 Note: If the drive has JP14 in and JP38 out, it does not respond to
 a START/STOP UNIT command.


 JP41/34  Terminator Power Selection
 -----------------------------------
 Power to the terminators may come internally from the drive, or
 externally from the SCSI bus.

   JP34  OPEN
 x JP41  CLOSED  Terminator power is internal, from the drive

   JP41  OPEN
   JP34  CLOSED  Terminator power is external, from the SCSI bus


 With both JP41 and JP34 in, terminator power is provided from the
 drive and to the SCSI bus. Hence, the drive is at one end of the SCSI
 bus with terminators in place and is also supplying terminator power
 for the device at the other end of the SCSI bus.


 JP18  Write Protect Option
 --------------------------
   JP18  CLOSED  Data cannot be written to the drive; only READ opera-
                 tion can be executed.

 Installation of JP18 grounds the remote write protect line, J2, pin
 seven, forcing WRITE PROTECT on, and prevents remote control through
 J2-7 on the ten-pin connector.

 As shipped from the factory, JP18 is out, allowing normal reading/
 writing, or optional remote control through the J2 connector.


 JP40  Parity Option
 -------------------
  x JP40  CLOSED  Enables odd parity detection in the drive.
          OPEN    Disables odd parity detection in the drive.

 Odd parity is always generated by the drive and provided to the SCSI
 bus.


 Other Jumppers
 --------------
 Other jumper positions are not user selectable and are shipped as
 indicated in Tables below. The user should avoid changing these
 jumpers, or improper operation may occur.

   +-----------------+

 The drive will operate in all axis (6 directions).


 Mounting
 --------
 The disk drive may be mounted in any orientation. In any final
 mounting configuration, ensure that the operation of the three shock
 mounts which isolate the base casting from the frame is not
 restricted. Certain switching power suppplies may emanate electrical
 noise, which can degrade the specified read error rate. For best
 results, orient the drive so that the PCB assembly is not adjacent to
 these noise sources.

 Caution: The XT-4000S disk drive should be handled with extreme care.
 Do not bang or drop the drive.


 Mounting Holes
 --------------
 Eight mounting holes, four on the bottom and two on each side, are
 provided for mounting the drive into an enclosure. The size and
 location of these holes are identical to industry standard floppy
 drives.

 Caution: The casting is very close to the frame mounting holes in
 some locations. Mounting screws lengths must be chosen such that no
 more than 0.125 inch of the screw is available to enter the frame
 mounting hole. The torque applied to the mounting screws must be
 between 9 and 12 inch pounds.


 J1 SCSI Connector
 -----------------
 Connection to J1, the SCSI interface connector is via a non-shielded
 fifty-conductor connector consisting of two rows of twenty-five
 female contacts on 0.1 inch centers. Recommended strain-relief
 connectors are AMP part-number 1-499506-2, or Dupont part number
 669002 (66900-250). Use of a keyed connector is strongly recommended.


 J2 Auxiliary Connector
 ----------------------
 Connector J2 is an auxiliary connector providing remote control of
 write protect and SCSI ID, and the ability to carry the LED signal
 beyond the drive. The auxiliary connector is a Berg 68451-121,
 ten-pin part. The mating connector is a 3M 3473-6010 part.


 J3 Power Connector
 ------------------
 The DC power connector, J3, is a four-pin AMP MATE-N-LOCK connector,
 part number 350543-1. The recommended mating connector is part
 number 1-480424-0. using AMP pins part number 350078-4 (strip) or
 part number 61173-4 (loose piece).


 J4 DC Logic Ground
 ------------------
 The DC logic ground connector at the back of the HDA, J4, is a
 Faston-type connector, AMP part number 61761-2. The recommended
 mating connector is AMP part number 62187-1. If wire is used, the
 hole in J4 will accommodate a maximum wire size of 18 AWG maximum.
 This ground is optional.

 Note. The frame of the disk drive is insulated from the HDA and,
 hence the DC logic ground. The frame is electrically connected to the
 computer system chassis when mounted in a computer system. Normally
 the chassis, and hence the frame of the drive, is at earth ground.


 Sector Size
 -----------
 The drive is shipped from the factory formatted with 512 byte
 sectors. Configuration parameters are default values in all optional
 cases. It is recommended that users reformat the drive with the
 user's sector size, using the Plist and the user's configuration
 parameters.


 Interface Termination
 ---------------------
 SCSI devices require proper interface termination. 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 drive is in the middle of the string, remove its terminators.

 Pin one is on the end of the terminator that is marked with a dot.
 Note that the hole/solder pad for pin one has a square outline,
 whereas all others have a round outline. Pin one is oriented toward
 the power connector, J3.

 Note: All terminator packs (RN17 through RN19) must be oriented
 with the dot toward J3 for the drive to work properly.

 As shipped, interface signal lines are terminated with three
 removable 220/330 ohm resistor network packs.

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

 Devices receiving the drive inputs should be SCHMITT trigger type
 to improve noise immunity; 74LS14, 74LS240, or equivalent. The
 initiator should not load bus with more than one standard low power
 Schottky transistor-transistor logic (LSTTL) input load per line, and
 should terminate all signals with 220/330 ohm terminators.


 Removable Faceplate
 -------------------
 The faceplate may be removed in installations where it is not
 required. Remove the two C-clips and unplug the LED cable from the
 PCB.
