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 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.

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.

EXAMPLE:
To disable the Full ASCII Code 39, enter:

5. Enter one digit
<ENTER>
one digit
<ENTER>
from the keyboard. (The
range is 01 to 60).
The reader should beep twice after each
<ENTER>
.
6. Save and exit by typing
FZ<ENTER>
.
The reader should beep four
times.
EXAMPLE:
To set the maximum length of a Code 39 bar code to 12, enter:
/E/D/FF<ENTER>F1<ENTER>FV<ENTER>1<ENTER>2<ENTER>
FZ<ENTER>
Code 39 Settings:
Enable/Disable Code 39
If enabled, Code 39 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.
SELECTION CODE: F1
Code 39 Enable
A
Code 39 Disable
B
Full ASCII
Standard Code 39 symbology supports only 43 characters. This can be
expanded by using character pairs to identify the full ASCII 128 character
set. When this option is ON, the reader will search for these character
pairs and transmit only the Full ASCII single character equivalent to the
host. If Full ASCII is enabled and used to read a standard Code 39
symbol, any combination of the defined character pairs will be reported to
the host as the single character equivalent. When this option is OFF and
a Full ASCII Code 39 symbol is scanned, the reader will report each of the
characters in the Full ASCII pair as individual characters. The reader has
no way of telling if the symbol is encoded in standard Code 39 or Full
ASCII Code 39.
