Standard 2 of 5/IATA Options
Check Digit
Label Length Format
The Standard 2 of 5/IATA symbologies have the following programmable features:
•Check Digit
•Label Length Format
•Read Verification
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, the scanner sends the Check Digit encoded in the bar code without verifying its accuracy.
Label length format permits the selection between variable length or fixed length formats. For best performance it is recomended to use the Fixed Length settings when your application requires only one or two label lengths.
Variable Length Format - directs the scanner to read all labels from the minimum label length to 50. Set Minimum Length as high as your application allows.
Minimum Label Length - selects the minimum label length that the scanner will recognize. The minimum label length for this symbology must be between 01 and 501.
Fixed length Format - 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:
Set First Fixed Length - instructs the scanner that the next two programming labels scanned will define the first fixed label length. This setting must be between 01 and 501 characters.
Set Second Fixed Length - instructs the scanner that the next two programming labels scanned will define the second fixed label length. This setting must be between 01 and 501 characters.
1.For this symbology, the scanner will decode up to 50 characters, but the actual length read will vary depending upon the interface type, and bar code physical size and quality.
