Appendix C: Bar Code Settings
Non-Decoded Scanners
Code 39
Security
This parameter controls the tolerance for decoding edge-to-edge bar codes (Code 93, Code
128, UPC/EAN). Lower values have a lower tolerance for misreads, but they also increase
the time it takes to decode the bar code. The default value of 30 is generally a good compro-
mise setting.
C.5.2
Code 39
Enabled
Set this parameter to
on
to enable “Code 39”.
Full ASCII
If this parameter is enabled, the char, %, and / are used as escape characters. The
combination of an escape character and the next character is converted to an equivalent
ASCII character.
Include Check
If this parameter is enabled, the check digit is included with the decoded bar code data.
AIAG Strip
If this parameter is enabled, the AIAG data identifier is removed from each decoded Code
39 label. The data identifier occurs in the first position next to the Code 39 start character. It
can be a single alphabetic character or a series of numeric digits followed by an alphabetic
character. This identifier defines the general category or specific use of the data contained in
the rest of the bar code.
Error Accept
If the “Err Accept” and “AIAG Strip” parameters are enabled, all label data without an
AIAG identifier character is accepted. If the “Err Accept” parameter is disabled and the
“AIAG Strip” parameter is enabled, the label data is not accepted.
MOD Checks
This parameter allows you to choose the check digit calculated:
MOD 43 Check, MOD 10
Check
or
None
.
Note: If your unit is operating with the Psion Teklogix TESS application, this parameter
should not be used in conjunction with the TESS AIAG feature. This is because the
hand-held performs the strip function before it processes the data through the AIAG
feature; if the prefix is stripped, the data is not identified as AIAG.
