value 5678 will be displayed if the
N.Chr
function is set to -4.
For the example above the value 3456 if the
N.Chr
function is set to 4 and the
dLAY
function is set to 2. For the
example above the value 4567 would be displayed if the
N.Chr
function is set to -4 and the
bAct
function is set
to 1.
Example 2: For string
<
STX
>
A12345678B
<
ETX
><
CR
>
the value 5678 will be displayed if the
N.Chr
func-
tion is set to -4 and the
ALPH
function is set to
OFF
or the value 678 will be displayed if the
ALPH
function is
set to
ON
i.e. the B character has been counted but the control character
<
ETX
>
has not. If the
ALPH
function is
set to
AII
the the B and
<
ETX
>
characters would both be counted and the display value for this string would be
78.

Serial input string decimal point insertion
Section:
IN 1
Display:
I.dPt
Range:
-1
to
8
Default Value:
-1
Default Access Level
CAL
Function number
4d14
In some systems the transmitting unit may display a decimal point position but not transmit the decimal point as
part of the serial data. The
I.dPt
function can be used to inform the instrument of the required position of the
decimal point on the display. The decimal point position of the result shown on the display is set via the
dCPt
function. If the
I.dPt
function is not needed then it should be left at the default setting of
-1
which will disable
the function.
Example: Transmitted string is 234 with no decimal point sent. With
dCPt
set to
0.1
and
I.dPt
set to
-1
the
displayed value will be
234.0
i.e. the display has been told to show one decimal place but no decimal point has
been sent. If we now change the
I.dPt
to
1
the displayed value will be
23.4
5.53
Alpha character display off or on
Section:
IN 1
Display:
ALPH
Range:
OFF
,
On
,
AII
Default Value:
AII
Default Access Level
CAL
Function number
4d15
Used only when
CodE
function =
UAL
or
ASCI
but applicable only to
ASCI
. Set this function to
OFF
to filter
alpha characters from the input stream i.e. only numeric characters, spaces, decimal points and negative signs will
be displayed and alpha characters ignored.
When set to
on
the instrument will display both alpha and numeric characters. Note: only a limited number of
alpha characters may be displayed due to the nature of 7 segment displays, non displayable characters (e.g. W and
X) will be ignored.
When set to
AII
alpha, numeric and control characters e.g. carriage returns will be included for counting purposes
in the string, see paragraph below.
This function can also affect the character skipping used by the
bAct dLAY
and
N.Chr
functions. For example
if
ALPH
is set to
OFF
then only numeric characters, spaces, decimal points and negative signs will be counted and
all other characters ignored. If
ALPH
is set to
on
then all characters except control characters will be counted. If
ALPH
is set to
AII
then all characters including control characters will be counted.
See the the
N.Chr
function, section
for further description and example.
