Connecting
AC
power
to
the scanner
The
scanner
power
cord
is a standard
three-wire
grounding
plug. This plug
will
fit
only
a
grounded
AC
outlet. Intended to be a safety feature, the
grounding
connector should not be removed. Use of a
transient
protected
power
source
is
highly
recommended
. The
scanner
would
ideally
be turned on and off with the
computer
.
Always
remove
the
power
cord from the AC
source
when
anyone
of
the
following
occurs
:
1. The
power
cord
or
plug becomes
damaged
.
2.
Any
liquids
are
spilled
into the
scanner
.
3. The
scanner
is exposed to
excessive
moisture
.
4. The case of the
scanner
has
become
damaged
.
5. The case is opened.
6.
You think the
scanner
is not functioning
properly
and
requires
repair
.
2-2 Setting the SCSI
10
Up to
eight
devices can
share
a SCSI
device
. These
are
each identified by SCSI
10
numbers
. Thus, a SCSI
10
can
have a value between 0 and 7.
There
are
no
implicit
regulations
regarding
the use
of
these numbers.
Typically, the
computer
controller
would be SCSI
10
number
0,
while
the SCSI
peripherals
would be 1
through 7.
A
minimum
of
two
devices
must
sit
on any SCSI bus. In
this case, one is designated as the
initiator
while
the
other
is the target. It is
possible
to have
many
configurations of
initiators
and
targets
on a bus.
More
than one
initiator
can be
present
on a SCSI bus. The
typical configuration is one
initiator
and one
or
more
targets. The LS-10/LS-10E
scanner
is
always
a target. In
the case we show
below
there
is
only
one
initiator
of
the
computer.
The SCSI
10
is
typically
set
by a switch on the
rear
of
the SCSI peripherals. The
default
SCSI
10
number
set
at
the factory is
10
#5.
