6-4 Trigger mode & some global settings
Trigger mode:
Good-read off- The TRIG pin must be pulled down once to activate scanning. The light source of engine
stops scanning when there is a successful reading or no code is decoded after the Stand-by duration
elapsed.
Momentary- The TRIG pin acts as a switch. Pull down the TRIG pin to activate scanning and pull up the
TRIG pin to stop scanning. The light source of engine stops scanning when there is a successful
reading or no code is decoded after the Stand-by duration elapsed.
Alternate- The TRIG pin acts as a toggle switch. Pull down and then pull up the TRIG pin to activate or
stop scanning.
Continuous- The engine always keeps scanning, and it does not matter when the TRIG pin is pulled
down or duration is elapsed.
Host- A host command issues the triggering signal. The scan engine interprets an actual trigger pull as
a momentary triggering option.
Standby duration- The TRIG pin pulled or host command activates scanning. The light source of engine
stops scanning when no code is successful decoded after the Stand-by duration elapsed.
Same barcode delay time: This feature is active only when the Trigger mode is in Alternate or Continuous
mode. Once a barcode has been scanned and output successfully, the laser beam must be off or
moved away from the barcode beyond delay time to active a next scanning on the same barcode.
When this parameter is set to be "0xFF", the delay time is indefinite.
Multiple confirm: If it is enabled, the engine 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
otherwise the labels of the type of barcode 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 a 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 types of barcode with fixed-length, e.g. UPC-A, UPC-E,
EAN-13, EAN-8 and China Post.
Global G1-G4 string selection: The engine 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 the chapters
of "String setting" and "String position & Number of truncated leading/ending character".
Example: Group 1 → set 01 or 10. Group 2 and 4 → set 24 or 42.
All valid settings include 00, 01, 02, 03, 04, 10, 11, 12, 13, 14, 20, 21, 22, 23, 24, 30, 31, 32, 33, 34, 40,
41, 42, 43, and 44.
