6-6 Scan mode & some global settings
Scan mode:
Good-read off – The trigger (Pin - 12 TRIG) must be pulled down once to activate scanning. The
scanner will stop scanning when there is a successful reading or no code is decoded after the Scan
standby duration elapsed.
Momentary – Pin TRIG acts as a switch. Pull down pin TRIG to activate scanning and pull up the
trigger to stop scanning. The scanner will stop scanning when there is a successful reading or no
code is decoded after the Scan standby duration elapsed.
Alternate – Pin TRIG acts as a toggle switch. Pull pin TRIG to activate or stop scanning.
Continuous – The scanner always keeps scanning, and it does not matter when pin TRIG is pulled
down or Scan standby duration is elapsed.
Host – A START_DECODE command issues the triggering signal. In this mode, the scanner
interprets an actual trigger pull as a Good-read off scanning option. There is a practical application
in
5-4 Decode by commands
.
Infrared-detecting – Barcode detected by the scanner’s infrared sensor issues the triggering signal.
In this mode, the scanner interprets an actual trigger pull as a Good-read off scanning option.
Same barcode delay time for 1D symbols: This feature is activated only when the Scan mode is in
alternate or continuous mode. Once a 1D barcode has been scanned and output successfully, the
optics module’s lights must be off or moved away from the barcode beyond delay time to active a next
scanning on the same barcode.
Same barcode delay time for 2D symbols: This feature is activated only when the Scan mode is in
alternate or continuous mode. Once a 2D barcode has been scanned and output successfully, the
optics module’s lights must be off or moved away from the barcode beyond delay time to active a next
scanning on the same barcode.
Multiple 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 symbols: 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. When setting of minimum and maximum reading length is equal, the scanner
works as a fixed-length barcode decoder.
Notes:
1. Please set the max./min. length for individual barcode in later chapters, if a special demand is
requested.
2. Both data and check digits contribute to 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 and China Post.
Global G1-G4 string selection: The scanner 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
6-46 String
transmission
and
6-45 G1-G4 string position & Code ID position
