Check Digit 
Check Digit calculates the check digit to verify that the check 
digit contained in the bar code label is correct.  If you enable this 
feature, your bar codes must contain a check digit.
If the check digit is not calculated, the digit will be sent regardless 
of settings for transmit or don’t transmit.  For example, if you 
choose to transmit check digit, but not calculate it, the scanner 
sends the check digit encoded in the bar code without verifying 
its accuracy.
Label Length Format
Label Length Format lets you choose between variable length or 
fixed length formats. For best performance, you should use the 
Fixed Length settings when your application requires only one or 
two label lengths.
• The Enable Variable Length Format bar code on page 86 
directs the scanner to read all labels from the minimum label 
length to 50. If you select variable length format, there is one 
more bar code label to scan:
• The Set Minimum Label Length bar code on page 86 
selects the minimum label length that the scanner will 
recognize. The minimum label length for this symbology 
must be an even number of characters between 02 and 50. 
Set the Minimum Length as high as your application 
allows.
• The Enable Fixed Length Format bar code on page 87 directs 
the scanner to read only one or two label lengths. If you select 
fixed length format, there are three bar code labels for 
programming your scanner to read either one or two fixed 
lengths. The labels are:
Note: For this symbology, the scanner decodes up to 50 
characters, but the actual length read varies depending upon the 
interface type, bar code physical size, and print quality.
