Code 39 Options
The Code 39 symbology has the following programmable features:
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.
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
bar code without verifying its accuracy. If you choose Don't
Transmit Check Digit, the scanner will remove the Check
Digit's contents before sending the bar code 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 — enables or disable the ability to decode
Code 39 Full ASCII labels.
Code 39 Minimum Label Length — sets 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.
