Check Digit
When Check Digit is selected, the reader takes the last character in the
decoded 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 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.
F1<ENTER>E to Not Calculate Check Digit and send whole data stream
F1<ENTER>F to Calculate and Send Check Digit
F1<ENTER>G to Calculate but not send Check Digit
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.
F1<ENTER>H to Send Start/Stop
F1<ENTER>I Do Not Send Start/Stop
Interleaved 2 of 5 Settings:
Enable/Disable Interleaved 2 of 5
If enabled, Interleaved 2 of 5 symbology will be read, subject to the
reading restrictions specified by this set of options. If disabled, the data
from the symbology will be disregarded.
F2<ENTER>A for Interleaved 2 of 5 Enable
F2<ENTER>B for Interleaved 2 of 5 Disable
Fixed Length
Interleaved 2 of 5 symbols are commonly printed in a fixed format
containing 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.
F2<ENTER>C to Turn Off Fixed Length
F2<ENTER>D to Turn On Fixed Length
Check Digit
When Check Digit is selected, the reader takes the last character in the
decoded 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 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.
