Code 39 Options
The Code 39 symbology has the following programmable features:
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.
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.
Start/Stop Characters
— you can choose either Send or Don't Send
depending on your host's interface requirement.
Code 39 Full ASCII
— enable or disable the ability to decode Code 39
Full ASCII labels.
Code 39 Minimum Label Length
— set the minimum label length
required for Code 39 labels (not including the check character). This
feature is provided to ignore small label segments, reducing the
possibility that a portion of a good label is incorrectly seen as an entire
label.
