Concatenation Req’d
Data in a Codabar symbol is framed by a start and a stop
character. Since they are not considered part of the
message, they are not ordinarily transmitted.
For applications requiring enhanced security, a check
character may be used. When enabled, the reader will
assume that the last character is a check character, and
will use it to verify the accuracy of the scanned data. If no
error is detected, the data will be transmitted.
When required, the check character will be verified, but will
not normally be transmitted. Enable this option to transmit
the checksum, when planning to verify transmitted data.
Codabar provides an option for concatenating messages
of adjacent symbols. The reader can distinguish those
messages which are concatenated from those that are not.
Select “NO” to prevent concatenation.
With this option enabled the reader
only responds to
concatenated symbols. If a particular application will
always use concatenation with Codabar, then this option is
recommended.

Data in a Code 39 Symbol is framed by a start and a stop
character. Since they are not considered part of the
message they are not ordinarily transmitted.
For applications requiring enhanced security, a check
character can be used. When enabled, the reader will
assume that the last character is a check character, and
will use it to verify the accuracy of the scanned data. If no
error is detected, the data will be transmitted.
When required, the check character will be verified, but will
not normally be transmitted. Enable this option to transmit
the checksum, when planning to verify transmitted data.
The code 39 specification provides a means of encoding
the full ASCII set of characters by using two–character
sequences made up of one of the four Code 39 characters
($ + % /) followed by one of the 26 letters as shown in the
Full ASCII Code 39 chart (on page 14). The reader cannot
distinguish Code 39 labels encoded in full ASCII mode
from those encoded in standard mode. Use this option to
direct the decoder which mode to assume.
The Code 39 specification provides a means of appending
data messages. If the first data character of a Code 39
symbol is a SPACE, then data following the SPACE can be
appended to a storage buffer. PDF Capable readers don’t
have an append buffer; therefore this function isn’t
available. When append option is selected, any leading
SPACE is removed from the transmitted message.

Xmit Check Digit
For applications requiring enhanced data security, a check
character can be used. When enabled, the reader will
assume that the last digit is a check digit, and will use it to
verify the accuracy of the scanned data. If no errors are
detected the data will be transmitted.
When required, the check digit will be verified, but will not
normally be transmitted. Enable this option to transmit the
check digit, when planning to verify the transmitted data.
Code 11
Check Digits
The Code 11 specification recommends the use of two
check digits. The PDF Capable reader may be
programmed to read Code 11 symbols with only one check
digit. The reader cannot autodiscriminate the number of
check digits encoded in a symbol.
