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

 TERMPWR (Terminator Power)
 --------------------------
 Generally, the host is the only device on the SCSI bus required to
 provide TERMPWR for the bus. To ensure that there is a sufficient
 level of power along the entire SCSI bus, Digital Equipment
 Corporation recommends that all devices on the SCSI bus supply
 TERMPWR (if they are capable). SCSI devices are protected by a diode
 or similar semiconductor to prevent back flow of the terminator
 power when more than one device supplies this power.


 TERMPWR

               Header may ++     | To provide TERMPWR, install the
               be 2-pin,  ++     | TERMPWR jumper at the following

                                     +--+



 SCSI Bus Termination
 --------------------
 Both ends of the SCSI bus cable must be terminated. One end is
 terminated at the host. The other end must be terminated by the last
 SCSI device on the SCSI bus.

 Note
 Do not install Models DSP3105D (differential) or DSP3210WD (wide,
 differential) at the end of the bus. DSP3105D and DSP3210WD
 drives can not provide bus termination.

 The DSP3160W/3210W contain internal components to provide Active
 Termination of the SCSI bus.

 Configure the drives to provide Active Termination by installing
 a shunt jumper at the drive's Option connector across pins 9 and
 10. If active termination is not required for this drive, make
 sure that the jumper is not installed.

       |oXoooo| Connector
       |oXoooo|

 SCSI ID (Address) Selection
 ---------------------------
 Each device on the SCSI bus must have a unique SCSI ID number
 assigned to it.
 The ID numbers for 8-bit SCSI drives range from 0 through 7. For
 16-bit SCSI drives, the numbers range from 0 through 15.

 Configure the drive's SCSI ID at the Option connector by installing
 shunt jumpers across pins 1-2, 3-4, 5-6 and 7-8.

 Configure Optional Features
 ---------------------------
 CAUTION
 The 5-volt signals of two or more drives should not be connected
 together or to any other current source by using the Option
 connector. Doing so may cause drive malfunction or component damage.

 Care must be taken when connecting the ground signals of two or
 more drives together to avoid ground loop problems. Ground loops
 may cause drive malfunction.

 The following optional features can be configured according to your
 system requirements. These features include:

 - Notification of AC power failure

 - Spindle synchronization

 - Write protection

 - Spin delay


 AC Failure Notification
 -----------------------
 The host system (or power supply) can warn the drive of an impend-
 ing AC failure by asserting the signal AC_LOW L. This is an active
 low signal (low means power failure).

 NOTE
 The system should provide this warning at least 10 milliseconds prior
 to failure for this feature to be operational.

 To utilize this feature, connect the system's AC power warning
 signal to the referenced AC_LOW L pin on the Option connector.
 When the host system asserts the AC_LOW L warning to the drive, the
 drive prevents write-spliced for outstanding writes.

            |oooooo|Option Connector

          | 12+----+
          |   +------ LOGIC_GND L
          +---------- AC_LOW L



 Spindle Synchronization
 -----------------------
 DSP3000 Series drives support synchronized spindle operation. Master
 or slave synchronized operation is set through a SCSI Mode Select
 Page.

 When the drive operates as a Master, it generates a spindle
 synchronization reference signal (SPINDLE_SYNC_REF L). When operating
 as a slave, the drive synchronizes its spindle according to the
 SPINDLE_SYNC_REF L input reference. The drive always maintains local
 speed regulation when no reference signal is applied.

 NOTE
 The reference signal must originate from drives with the same
 electronics modules. Fo example, connect Model DSP3160 only with
 another DSP3160 drive. Do not connect the SPINDLE SYNC signal
 so that of any other model disk drive. Otherwise, the drive may mal-
 function.

 When connecting multiple drives together for spindle synchronization,
 be sure to use proper cabling techniques to avoid ground loop
 problems.


 Spindle Sync Connection
 -----------------------
 The following figure shows the SPINDLE SYNC and associated ground
 connection pin on the Secondary Option connector.

            |o *+--- LOGIC_GND L
            |oo@+--- SPINDLE_SYNC_REF L
            +1-5+


 Write Protection
 ----------------
 DSP3000 Series support either the Write Protect or Spin Delay
 mode. If your drive supports the Write Protect mode, install the
 jumper across the referenced pins of the Option connector.


 To disable Write Protection from 16-bit drives, remove the jumper
 from across 1 and 2 of the Secondary Option connector.


 Note that when the Write Protect Mode bit is set to a 1, automatic
 spin up occurs at power on.

            |Xoo|Connector
            +1--+


 Spin Delay
 ----------
 DSP3000 Series drives support either the Write Protect or Spin
 Delay mode.

 If your drive supports the Spin Delay mode, you can program the
 drive automatically spin-up at power on by installing the jumper
 across the referenced Option connector pins.


 To have spin-up controlled by a Start/Stop Unit command, remove the
 jumper.

            |X o|Secondary Option
            |Xoo|Connector
            +1--+


 Remote Features
 ---------------
 Remote features can be configured at the drive's Option connector
 to meet your system requirements. The remote features supported
 are:

  - Remote SCSI ID selection

  - Remote Busy and Fault display


 Remote SCSI ID Selection
 ------------------------
 The Option connector enables you to set the drive's SCSI ID from an
 external (remote) switch or control panel.


 Configure the drive for remote ID selection by removing the
 SCSI ID jumpers (if present) from the SCSI ID pins. Then connect the
 leads from the external selection switch to the referenced pins.
 Observe the following guidelines while doing so.

 - ID bit 0, at Pin 1, is the Least Significant Bit.

 - SCSI ID bits 0, 1, 2, and 3 are active LOW signals. That is, the
   bit is a 1 if the corresponding remote switch is closed to ground.

 - For Models DSP3160W/3210W/3210WD, use pin 10 common ground return
   of all four ID bits.

            12-----+     (Pins 1,3,5,7)



 Remote Busy and Fault Status Display
 ------------------------------------
 The drive's Busy and Fault status can be monitored by connecting
 a remote Busy and a remote Fault display LED to the drive's Option
 connector.


 Remote Busy
 -----------
 The remotely monitor Busy status of the drive, connect the cathode
 side of the remote Busy LED to the BSY_OUT L pin. The anode side of
 the LED connects to the +5VDC OUT pin.


 Remote Fault
 ------------
 The remotely monitor Fault status of the drive, connect the cathode
 side of the remote Fault LED to the FLT_OUT pin. The anode side of
 the LED connects to the +5VDC OUT pin.

 You can mount the disk drive in any position. The drive (with bezel)
 attaches to the system bay and accept #6-32 screws. Screws should
 not exceed 0.25 inch (6.25 millimeters) in length, otherwise
 damage to the PCB may result.


 Mounting and Bezel Options
 --------------------------
 Bezels and mounting brackets are available from Digital Equipment
 Corporation for mounting the drive in either 3.5-inch or 5.25-inch
 form factor bays.

 LED Indicators
 --------------
 The green Busy LED illuminates to signify the drive is working on a
 SCSI command. The amber Fault LED indicates a fault status.

 Both the Busy and Fault indicators light briefly during power up.
 This serves as a hardware and lamp test.

 During a calibration operation, the Busy LED is illuminated and the
 Fault LED flashes. Calibrations occur following some firmware up-
 grades. Generally, calibration periods last only about five minutes,
 after which the drive comes online and both indicators go out.

 If the Fault indicator lights at any other time, the drive has failed
 and likely requires service (unless the Fault LED was turned on by
 means of a MODE SELECT command).

 Remote Busy and Fault indicators can be connected to the Option
 connector to provide status display at a remote location or panel.


 Power-On Tests
 --------------
 After power is applied, and before spinup is completed, the drive
 performs selftest diagnostics prior to making itself visible on the
 SCSI bus. These intitial selftest check most of the electronics that
 control HDA, but not the SCSI transceiver or SCSI connector.

 After spinup, additional tests complete selftest coverage of the
 electronics module and the HDA. The unit appears not ready to the
 host between completion of the initial selftests and completion of
 the drive's post spinup tests.
