Code 39
Full ASCII
If this parameter is enabled, the characters +, %, and / are used as escape characters.
The combination of an escape character and the next character
is converted to an equivalent ASCII character.
Decode Performance
If this parameter is enabled, one of three decode levels can be chosen in the “Decode
Performance Level” parameter.
Decode Perf. Level
This parameter provides three levels of decode performance or “aggressiveness” for
Code 39 symbols. Increasing the performance level reduces the amount of required
bar code orientation – this is useful when scanning very long and/or truncated bar
codes. Keep in mind that increased levels reduce decode security.
When you double-tap on this parameter, a dialog box is displayed in which you can
enter a decode performance level of between 1 and 3.
Field Size/Chars
Field Size
The field size is the length of the field after the first character is stripped and
the prefix and suffix characters are added. If the field size is non-zero, only
bar codes of that length are passed through.
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.
