Decoded (Internal) Scanners
Double-tapping this parameter displays a list of options. If Ignore is chosen,
UPC/EAN is decoded and the supplemental characters are ignored. If Decode is
chosen, UPC/EAN symbols are decoded with supplementals. Autodiscriminate
works in conjunction with the Supp. Redundancy parameter.
Supp. Redundancy
With Autodiscriminate selected in the Supplementals parameter, “Supp.
Redundancy” adjusts the number of times a symbol without supplementals is
decoded before transmission.
When you double-tap on this parameter, a dialog box is displayed in which you can
enter a value between 2 and 20. A value of 5 or above is recommended when
Autodiscriminate is selected and you are decoding a mix of UPC/EAN symbols with
and without supplementals.
Security Level
This parameter controls the tolerance for decoding edge-to-edge UPC/EAN bar
codes. Double-tapping on this parameter displays a dialog box in which you can
choose a level from 0 to 3. Lower values have a lower tolerance for misreads, but
they also increase the time it takes to decode the bar code.
Linear Decode
“Linear Decode” applies to code types containing two adjacent blocks (e.g., UPC-
A, EAN-8, EAN-13). When enabled (set to on), a bar code is transmitted only when
both the left and right blocks are successfully decoded within one laser scan. This
option should be enabled when bar codes are in proximity to each other.
2D UPC Half Block Stitching
Setting this parameter to on enables “UPC Half Block Stitching” for the SE 3223
omnidirectional engine only.
5.27.1.12 Code 93
Enabled
Set this parameter to on to enable “Code 93” or off to disable it.
