7-2 Some global settings
Multiple confirm: If this parameter is set to be lager than zero, the engine will require several successful
reads of same-decoded-data to confirm a valid reading. The number of successful reads can be different
according to different types of barcode. As the number of Multiple confirm gets larger, the engine’s
aggressiveness decreases. The number of successful reads required for different types of barcode is
listed below, which is related to the parameter of Multiple confirm.

Global Max./Min. code length: These two lengths are defined as the valid range of decoded barcode
data length. Make sure that the minimum length setting is no greater than the maximum length setting, or
otherwise the labels of the type of barcode will not be readable. In particular, the same value can be set
for both minimum and maximum reading length to force the fixed length barcode decoded.
Notes:
1. Please set the max./min. length for individual barcode in later sections, if a special demand is
requested.
2. The number of check digits is included in max./min. code length.
3. These two settings have no effect on the types of barcode with fixed-length, e.g. UPC-A, UPC-E,
EAN-13, EAN-8 and China Post.
Global G1-G4 string selection: The engine offer one or two string group for ALL types of barcode. By
setting one or two digits to indicate which string group you want to apply. You may refer to the chapters
of “String setting” and “String position & Number of truncated leading/ending character”.
Example: Group 1 → set 01 or 10. Group 2 and 4 → set 24 or 42.
All valid settings include 00, 01, 02, 03, 04, 10, 11, 12, 13, 14, 20, 21, 22, 23, 24, 30, 31, 32, 33, 34, 40,
41, 42, 43, and 44.
Element amendment: If it is enabled, the engine can read the barcode comprised with bars and spaces
in different scale.
Printable character only: If it is enabled, the engine will output the printable characters only, i.e. in ASCII
from 20H to 7EH.
Decoder optimization: If it is enabled, the engine will optimize the engine with error correction. This
function is not effective for all types of barcodes.
