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
