SYMBOLOGY
SELECTION
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 Full ASCII Mode.
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.
