mode & some global settings
Scan mode:
Good-read off- The trigger button must be pressed once to activate scanning. The scanner will
stop scanning when there is a successful reading or no code is decoded after the Stand-by
duration elapsed.
Momentary- The trigger button acts as a switch. Press button to activate scanning and release
button to stop scanning. The scanner will stop scanning when there is a successful reading or no
code is decoded after the Stand-by duration elapsed.
Alternate continue- The trigger button acts as a toggle switch. Press button to activate or stop
scanning.
Continue- The scanner always keeps scanning, and it does not matter when the trigger button is
pressed or duration is elapsed.
Timeout off- The trigger button must be pressed once to activate scanning. The scanner will
stop scanning when no code is successful decoded after the Stand-by duration elapsed.
Auto-detection- By setting Enable, the scanner will start operating if any nearby barcode has
been detected. The scanner will stop scanning when there is a successful reading or no barcode
is decoded after the Stand-by duration elapsed. Once the scanner stops scanning, the present
barcode must be removed to enable Auto-detection.
Same barcode delay time: If a barcode has been scanned and output once successfully, the
scanner must move away from the barcode beyond delay time to active scanning the same
barcode. When this feature is set to be
“0xFF”, then the delay time is indefinite.
Double confirm: If it is enabled, the scanner will require a several times of same-decoded-data to
confirm a valid reading.
Global Max./Min. code length for 1D symbol: These two lengths are defined as the valid range
of decoded 1D barcode data length. Make sure that the minimum length setting is no greater than
the maximum length setting, or otherwise the labels of the symbol 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 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 symbols with fixed-length, e.g. UPC-A, UPC-E, EAN-
13, EAN-8 and China Post.
Global G1-G4 string selection: The scanner offer one or two string group for ALL symbols. By
setting one or two digits to indicate which string group you want to apply. You may refer to 3-38
G1-G6 & C1-C3 & FN1 substitution string setting and 3-39 G1-G4 string position & Code ID
position .
Example: Group 1
→
set 01 or 10. Group 2 and 4
→
set 24 or 42.
