Fixed Length
Interleaved 2 of 5 symbols are commonly printed in a fixed format contain-
ing a fixed number of characters. If this option is ON, the first Interleaved 2
of 5 symbol scanned after power up will set the length of any other symbols
scanned afterwards. If the succeeding scans do not match the length of the
first scan, the scan is rejected by the reader. Power must be reset before an
Interleaved 2 of 5 symbol of a different length will be accepted.

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.

FEBRABAN Conversion:
If enabled, the original 44-digit Interleaved 2 of 5 data will be converted to
48- digit FEBRABAN code. Otherwise, the original 44-digit data will not be
changed.
