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

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.
