Decoded (Internal) Scanners
Code 128
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.
5.13.2.5  Code 128
Enabled
Set this parameter to on to enable “Code 128”.
Enable GS1-128/GS1 US
Previously UPC/EAN and UCC, these types of bar codes include group separators and 
start codes.
Enable ISBT 128
To successfully scan this variation, “Enable ISBT 128” must be set to on.
Decode Performance
If this parameter is set to on, one of three decode levels assigned to the Decode Performance 
Level
 parameter can be selected.
Decode Perf. Level
This parameter provides three levels of decode performance or “aggressiveness” for Code 
128 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.
Length Restriction
Refer to “Length Restriction” on page 142 for details. 
Note: For Code 39 bar codes, the “AIAG Strip” is performed before the “Strip Leading”.
