140 Psion Teklogix 8525 G2/8530 G2 Vehicle-Mount Computer User Manual
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.
5.5.13.5 Code 39 Settings
Enabled
Set this parameter to on to enable Code 39 or ‘off’ to disable it.
Full Ascii
If this parameter is enabled (set to on), 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 (set to on), the check digit is included with the decoded
bar code data.
AIAG Strip
If this parameter is enabled (set to on), 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 8525 G2/8530 G2 vehicle-mount performs the strip
function before it processes the data through the AIAG feature; if the pre-
fix is stripped, the data is not identified as AIAG.
Error Accept
If the Err Accept and AIAG Strip parameters are enabled (set to on), all label data
without an AIAG identifier character is accepted. If the Err Accept parameter is
disabled and the “AIAG Strip” parameter is enabled (set to on), the label data
is not accepted.
