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 ori-
entation – 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
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.

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.

Strip Trailing
The value entered in this parameter determines the number of characters that will be 
removed from the end of the bar code before the suffix character is added.
