Example Code
= dat
al12og
35
- 7 -
The following is an example of a very complex string where ? and* are used both as commands and as characters:
Match String
= *
45<NUL>??*??AC<NUL>*251?*
Example Code
= GEN
45?3
ius
dsAC*2516
300
NOTE
For Codabar codes the start/stop characters must be considered in the match conditions.
For all codes which use check digits, if the Check Digit is transmitted, it must be considered in the
match conditions.
Match Direction Rule
This parameter defines the direction, according to which a code can be transmitted. The direction refers to the code
direction with respect to the scan line, in particular:
Forward = the code start character precedes the stop character in the scan line (Start Ch + Code + Stop Ch)
Reverse = the code stop character precedes the start character in the scan line (Stop Ch + Code + Start Ch)
Selections:
Disable
all codes are transmitted no matter what the direction is
Forward
all codes having a forward direction are transmitted
Reverse
all codes having a reverse direction are transmitted
Min/Max Code Position Filter
These parameters specify where in the scan line a particular code can be found. The scan line is divided into 256
physical positions.
The code position is determined at the
center
of the label and is checked to be between the
Min
and
Max
parameters
specified in the configuration. These values go from 0 to 255.
Selections: a value from
0
to
255
Since the Min and Max values depend on many factors such as: the scanner model, number of mirrors, scan speed,
aperture angle, etc.., typical values are not applicable.
NOTE
You must set a range of positions in which the code will be found. A typical range is 5 positions
(i.e. min = 25, max = 30).
If you want to disable this verification, set
Min
=
0
and
Max
=
255
, which means the code can occur anywhere in the
scan line.
Start Char Tx
This parameter is available only for Codabar code symbologies. It allows transmitting the code start character:
Selections:
Disabled
the character is not selected;
Lower Case
the character is transmitted in lower case;
Upper Case
the character is transmitted in upper case.
Stop Char Tx
This parameter is available only for Codabar code symbologies. It allows transmitting the code stop character:
Selections:
Disabled
the character is not selected;
Lower Case
the character is transmitted in lower case;
Upper Case
the character is transmitted in upper case.
