Scan
Scanning mode:
Good-read off- The trigger button must be pressed to
activate scanning. The light source of imager 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.
Alternate- The trigger button acts as a toggle switch. Press
button to activate or stop scanning.
Timeout off- The trigger button must be pressed to activate
scanning, and imager stops scanning when no code is
decoded after the Stand-by duration elapsed.
Continue- Imager always keeps reading, and it does not
matter when trigger button is pressed or duration is elapsed.
Test only- For test of scan performance only. It is improper to
be utilized to check the accuracy of transmitted data.
Auto-sensing- Similar to Continue, it automatically detects
and decodes bar codes in your scanner ’ s field of view. If no
bar code is decoded after the stand-by duration elapsed, the
light bar will be turned off. You can move your scanner or pull
the trigger to wake it up.
Double read timeout: It determines the duration of Double
confirm . For example, if you set 5 times in Double confirm
and set 10 milliseconds in Double read timeout , the
decoder will decode a bar code 5 times in 10 milliseconds.
You need to turn on Double confirm to use this feature.
Double confirm: It determines how many times the decoder
needs to confirm a bar code.
Supplement Check Counter: It will be more reliable to read
the barcode with extension (supplement) like UPCE/A or
EAN-8/13, but slow down the decoding speed when this
counter is set more.
