Chapter 5: Configuration

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.

Note: For Code 39 bar codes, the “AIAG Strip” is performed before the “Strip Leading”.

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
