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.
