Check Digit
When Check Digit is selected, the reader takes the last character in the de-
coded data stream as a check digit. It then calculates the correct check digit
for the remaining data and compares it to the last data character. If it is the
same, the data is accepted. If not, the data is rejected. With the Calculate and
Send Check Digit option, the reader will send the check digit as part of the
data stream. If the Calculate but Do Not Send Check Digit option is selected,
the reader will strip it from the data stream before transmission. If the Check
Digit is not calculated, the reader will assume the last data character read
from the symbol is part of the data stream and will not make a comparison
test.
SELECTION CODE: F1
Do Not Calculate Check Digit but Send Whole Data Stream E
Calculate and Send Check Digit F
Calculate but Do Not Send Check Digit G
Send Start/Stop Characters
A unique character is used as the first and last character in a Code 39 symbol.
It is printed as an asterisk (*). Some applications require that these characters
be transmitted with the data while others specify that they must not be sent.
