3-5 Scan trigger mode & some global settings
Scanning mode:
Good-read off-The trigger button must be pressed once to activate scanning. The light source of
scanner stops 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 light source of scanner stops 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 light source of scanner
stops 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 object has been detected.
The laser light of scanner stops scanning when there is a successful reading or no code is decoded
after the Stand-by duration elapsed. Once the laser light stops scanning, the present object must be
removed to enable Auto-detection.
Note: Restoring the default settings by the host command or scanning the barcode that will not affect
the scanning mode settings.
Standby duration: The duration time for a single scanning attempt.
Same barcode delay time: If a barcode has been scanned and output once successfully, the laser beam
must be off or moved away from the barcode beyond delay time to active next scanning the same barcode.
When this feature is set to be “0xFF”, then the delay time is indefinite.
Multiple confirm: If this parameter is set to be larger than zero, the scanner 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 scanner’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.
