Transfer
Modes
The
unit’s
serial
interface
is
either
RS232
or
RS485,
depending
on
the
model.
Settings:
transfer
rate:
9.6
kBaud,
8
data
bits,
1
stop
bit,
no
parity,
flow
control:
none
(half
duplex
mode).
There
are
two
possible
transfer
modes
for
the
serial
interface:
Poll
Mode:
By
user
interface
control,
a
parameter
will
be
set
or
requested.
Burst
Mode:
A
pre
‐
defined
data
string
(“burst
string“)
will
be
transferred
as
fast
as
possible
as
long
as
the
burst
mode
is
activated.
The
data
will
be
transferred
in
one
direction
only,
from
the
unit
to
the
user
interface.
V=P
“P“
starts
the
Poll
mode
(allows
to
request
or
to
set
parameters)
V=B
“B“
starts
the
Burst
mode
(data
will
be
transferred
as
fast
as
possible;
necessary:
data
string
definition
–
“Burst
string“)
$=UTIE
“$“
sets
the
parameter
combination
(“burst
string“)
“U“
unit
(°C
or
°F)
“T“
temperature
value
“I“
internal
temperature
of
the
sensing
head
“E“
emissivity
?X$
gives
the
burst
string
parameters
while
in
poll
mode
Return
from
the
burst
mode
to
the
poll
mode:
If
the
poll
mode
shall
be
activated
while
the
burst
mode
is
still
active,
send
a
character
and
within
the
following
3
seconds
the
command
V=P.
