3-7 Scan mode & some global settings
Scan mode:
Good-read off
– The trigger pin must be pulled down once to activate scanning. The scanner stops
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 stops 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
2-6-3 Decode by commands
.
Good-read on
– The trigger pin must be pulled down once to activate scanning. The scanner stops
scanning when no code is decoded after the Scan standby duration elapsed.
Auto-detection- Good-read on
– By setting Enable, the scanner will start scanning if any nearby
object has been detected. The scanner stops scanning when no code is successful decoded after
the Stand-by duration elapsed. Once the scanner stops scanning, the present object must be
removed to enable Auto-detection.
Auto-detection- Good-read off
– By setting Enable, the scanner will start scanning if any nearby
object has been detected. The scanner will stop scanning when there is a successful reading or no
code is decoded after the Stand-by duration elapsed. Once the scanner stops scanning, the present
object must be removed to enable Auto-detection.
Barcode detection:
In image auto-induction mode, barcode detection means that the scanner detects
an object similar to a barcode to trigger decoding, such as text, graphics, barcodes, and so on.
Barcode detection delay:
The barcode detection delay means that the detection function is enabled
when no object is detected within the set delay.
Same barcode delay time for 1D symbol:
If a 1D barcode has been scanned and output once
successfully, the scanner must output the same barcode data beyond delay time. When this feature is
set to be
“0xFF”, then the delay time is indefinite.
Same barcode delay time for 2D symbol:
If a 2D barcode has been scanned and output once
successfully, the scanner must output the same barcode data beyond delay time. 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-G6 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
3-44 G1-G6 & C1-C3
& FN1 substitution string setting
and
3-45 G1-G4 string position & Code ID position
.
Example: Group 1
→
set 01 or 10. Group 2 and 4
→
set 24 or 42.
All valid settings include 00, 01, 02, 03, 04, 05, 06, 10, 11, 12, 13, 14, 15, 16, 20, 21, 22, 23, 24, 25, 26,
30, 31, 32, 33, 34, 35, 36, 40, 41, 42, 43, 44, 45, 46, 50, 51, 52, 53, 54, 55, 56, 60, 61, 62, 63, 64, 65 and
66.
Element amendment:
If it is enabled, the scanner can read the barcode comprised with bars and
spaces in different scale.
Decoder optimization:
If it is enabled, the scanner will optimize the decoder with error correction. This
function is not effective for all types of barcode.
Data output delay in continue-scan mode:
If it is enabled, in the continue-scan mode, the scanner can
store the data while continue-scanning. The scanner will output the data after the predefined delay
