Code 39
Length Restriction
The parameters in this sub-menu allow you to define the length of the bar codes that will be
decoded using either the
Field Size
parameter or the
Minimum Size
and
Maximum Size
pa-
rameters (see below). The order of operation to either match the
Field Size
or determine if
the length falls between the
Minimum Size
and
Maximum Size
is as follows:
•
Strip the leading and trailing characters.
•
Add the prefix and suffix characters.
•
Count the number of characters remaining to either match the field size or determine if
the length falls between the minimum and maximum size.
Field Size
When a value is assigned for this parameter, only bar codes that match the field size exactly
can be transmitted. If a value is assigned to this parameter, a
Minimum Size
and
Maximum
Size
value is not required.
Minimum Size and Maximum Size
When a value is assigned to these parameters, only bar code lengths that fall between the
minimum and maximum value can be decoded. If values are assigned to these parameters, a
Field Size
value is not required.
Add/Remove Data
Prefix Char
This character, if non-zero, is added before a successfully decoded bar code. Press the key
you want to insert in the dialog box attached to this parameter. The ASCII/Unicode key
value of the keypress is displayed.
Suffix Char
This character, if non-zero, is added after a successfully decoded bar code. Press the key you
want to insert in the dialog box attached to this parameter. The ASCII/Unicode key value of
the keypress is displayed.
Strip Leading
This parameter determines the number of characters that will be removed from the begin-
ning of the bar code before the prefix character is added.
Note: For Code 39 bar codes, the “AIAG Strip” is performed
before
the “Strip Leading”.
