3-4 Scan mode & some global settings
Scan 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-The scanner will start scanning when an object closes to it. The light source of scanner
stops scanning when there is a successful reading or no code is decoded after the Stand-by duration
elapsed. The auto-detection function works again only after the object leaves the scanner. The trigger
button is still valid when the auto-detection is enabled.
Good-read identification-The scanner will start to scan when it receives a GOOD_READ_START
command (refer to “
4-14 GOOD_READ_START
”). The light source of scanner stops scanning when
there is a successful reading or no code is decoded after the Stand-by duration elapsed. If it decodes
successfully, the scanner will reply "<STX><]><CR><LF>". Otherwise, the scanner will reply
"<STX><CAN><CR><LF>". When it receives a GOOD_READ_STOP command (refer to “
4-15
GOOD_READ_STOP
”), the scanner will stop scanning immediately. In this scan mode, the scanner
still supports all the commands except START_DECODE and STOP_DECODE. Also, you can press
trigger to scan the configuration-barcode to configure parameter or firmware version display barcode
to get firmware version information. But if you scan the other barcodes, the scanner will not transmit
the decoding result. In other scan modes, the GOOD_READ_START command and
GOOD_READ_STOP command are invalid.
Note: Restoring the default settings by the host command or scanning the barcode has no affect on
the scanning mode settings.
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 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: 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
