Non-Decoded Scanners
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 compromise setting.
5.11.2.2 Code 39
Enabled
Set this parameter to on to enable “Code 39” or off to disable it.
Full Ascii
If this parameter is enabled, the characters +, %, 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.
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 pro-
cesses the data through the AIAG feature; if the prefix is stripped, the data
is not identified as AIAG.
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.
