• Read Verification
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.
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.
• 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:
