for sharing

AddlngExternal HardDrlves
You can add up to 6 hard drives or other devicesto thc A530 by
connecting thcm to the 25-pin external SCSI bus connector at the
back of thc A530 chassis. External SCSI deviccs must have thcir own
powcr suppliec.
SCSI stands for Ernll Comlrutcr Stendnrd l*ctf*cc and is the general
term for rn industry-wide specification governing how certain devices
should be connected to one another. The SCSI standard specifiesa
S0-wire data bus that can connect up to a maximum of 8 sep.lrate
individual devices. The controller, itself, is alwayscounted asone of
thcse8 devices.
By far, the most common type of SCSI device is a hard disk drive.
Hard disks make availableto computer users far greater amounts of
data storage than conventional floppy disla. They are also much faster
at finding and rclafng data than floppy drives. SCSI is not limited to
hard disks,holever. Equipment manutrcturers have produccd SCSI
document scAnners,printers, CD-ROM drive.s,and tape backup trnits.

UnitlDs
In orderto kecptrackof all thedeviccsattached
to the SCSIbus,each
one
musthaveauniqueID number. Usually,thisID number
corresponds
with its position
in the chain of deviccs,but not
necessarily.
AcccptableSCSI
ID numbers are
0-7. TheA530
Turbo'sSCSI controller,
itself,
will ahvaysbc dcsignated
asID #7.
The rernaining available
ID numbersarc0-6, with the internalhard
driveset
as
ID #0. Most userswill startnumberingtheir additional
SCSI
drivcsfrom I (eg.: DHI:, DH2:, CD3:,etc.).
Jumpers
& Terminatonr
Everydevicedesigned
to mect theSCSI specification
rnust
provide
somcway
of changing
the ID numberof the device. Hard drives
trsuallyemploy
aset
of jumperpins
for thispurpose. Thereare
a
numbcrof different
jurnper
configurations
employed
bythedifferent
hard drivc manufacturers,sowe will not attemptto describe
a
standard
methodhere. Rcferto thedocument
supplied
with your
particulrr brandof hrrd drive,or consult
with your GVPdealer.
Anotherrequircmcnt of theSCSIbus
isthat it mustbeclectrically
tcrnrinirtcdoncach end. MostSCSI
devices
rvillhave
solne
ureansof
installing
or applying
resistorsto electricallyterminatethc bus

devicesarcattachcdtogcthcrin "daisy
chain"
fashion,then both thc first andlastunits in the chainmust bc
terminated,but any
terminating
resistorson any intcnnediatcdevices
mustberemovedor disabled.
Again,there
isno industrystandard
mcthod for installingtcrmination
resistors.Mostharddrivesemploy
a
seriesof sockcted, comb-like
components
callcd
"resistor
packs.' Theseareusually
founddirectly
