Cache
Data
The
data
cache
is
a
set
of
binary
files
kept
on
the
hard
disk
of
the
computer
running
the
datalogger
support
software.
A
binary
file
is
created
for
each
table
in
each
datalogger.
These
files
are
set
up
to
mimic
the
storage
areas
in
datalogger
memory,
and
by
default
are
two
times
the
size
of
the
storage
area.
When
the
software
collects
data
from
a
CR800,
the
data
are
stored
in
the
binary
file
for
that
CR800.
Various
software
functions
retrieve
data
from
the
data
cache
instead
of
the
CR800
directly.
This
allows
the
simultaneous
sharing
of
data
among
software
functions.
Similar
in
function
to
CR800
final
storage
tables,
the
binary
file
for
a
datalogger
is
set
up
as
ring
memory.
This
means
that
as
the
file
reaches
its
maximum
size,
the
newest
data
will
begin
overwriting
the
oldest
data.
Calibration
Wizard
Software
The
calibration
wizard
facilitates
the
use
of
the
CRBasic
field
calibration
instructions
FieldCal()
and
FieldCalStrain()
.
It
is
found
in
LoggerNet
(4.0
or
higher)
or
RTDAQ
.
Callback
A
name
given
to
the
process
by
which
the
CR800
initiates
telecommunication
with
a
PC
running
appropriate
CSI
datalogger
support
software.
Also
known
as
"Initiate
Telecommunications."
CD100
An
optional
enclosure
mounted
keyboard
display
for
use
with
the
CR1000
and
CR800
dataloggers.
See
the
appendix
Keyboard
Display
(p.
545
).
code
A
CRBasic
program,
or
a
portion
of
a
program.
Com
port
COM
is
a
generic
name
given
to
physical
and
virtual
serial
communications
ports.
constant
A
connector
is
a
device
that
allows
one
or
more
electron
conduits
(wires,
traces,
leads,
etc)
to
be
connected
or
disconnected
as
a
group.
A
connector
consists
of
two
parts
—
male
and
female.
For
example,
a
common
household
ac
power
receptacle
is
the
female
portion
of
a
