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.

Strip Leading

This parameter determines the number of characters that will be removed from the 
beginning 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.
