SYMBOLOGY SELECTION
STANDARD 2 OF 5
The Standard 2 of 5 symbology has the following programmable features:
Normal or IATA Selection — offers a choice between using "normal" format or IATA (International Airline Transport Association) format within the Standard 2 of 5 symbology. IATA is used for international tickets and boarding passes.
Check Digit — calculate the Check Digit to verify that the Check Digit contained in the barcode label is correct. If you enable this feature, your barcodes must contain a Check Digit.
NOTE
If you are using the IATA format, ONLY labels with 15 characters will actually have their Check Digit calculated per IATA standards (recommended Practice 1720a, attachment D, current 6/95). Labels with lengths other than 15 characters will be passed without any check digit calculation.
You may also choose to transmit or not transmit the Check Digit independent of whether the Check Digit is calculated by the scanner. If you choose to Transmit Check Digit, but not calculate, the scanner sends the Check Digit encoded in the barcode without verifying its accuracy. If you choose Don't Transmit Check Digit, the scanner will remove the Check Digit's contents before sending the barcode data to the host.
Label Format — provides the selection between fixed or variable length labels. If your application has labels with specific fixed lengths, we recommend selecting fixed lengths to improve read rate and avoid short reads.
You can select any valid number of digits for reading specific length labels only. Read the following details for specific Standard 2 of 5 limits.
