•
Continuous Mode:
The scanner is always scanning.
•
Auto Power Off Mode:
The scanner will start scanning once the switch is
triggered. The scanning continues until a preset scanning period (
Scanner
Time-Out Duration
) is expired. Unlike the Auto Off mode, the scanner will
continue to scan and the scanning period is re-counted each time there is a
successful read.
•
Alternate Mode:
The scanner will start scanning once the switch is
triggered. The scanner will continue scanning until the switch is triggered
again.
•
Momentary Mode:
The scanner will be scanning as long as the switch is
depressed.
•
Repeat Mode:
The scanner is always scanning just like Continuous Mode.
But now the switch acts like a “re-transmit button”. If the switch is triggered
within 1 second after a good read, the same data will be transmitted again
without actually reading the barcode. This “re-transmit button” can be
triggered as many times as user desired, as long as the time between each
triggering does not exceed 1 second. This scan mode is most useful when
the same barcode is to be read many times.
•
Laser Mode:
This scan mode is used on laser scanners. The scanner will
scan once when the trigger is pressed. The scanning continues until a
barcode is read, the trigger is released or a preset scanning period (
Scanner
Time-Out Duration
) is expired.
•
Test Mode:
The scanner is always scanning. The scanner will decode
repeatedly even with the same barcode.
By default, the scan mode is Auto Off mode for scanners with trigger switch, and is
Continuous mode for switch-less scanners.
3.4 Auto-Sense
Auto-Sense is for WWS800 only and used in conjunction with the auto-sense
stand. It will enable the scanner to start scanning once a barcode is brought within
Range of the scanner. This will activate the LEDs and the scanner will start
decoding the barcode. The auto-sense mode works only under Auto Off mode or
Laser mode only.

3.5 Re-read Delay
If the scanner mode is set to
Continuous
,
Auto Power Off
,
Alternate
, or
Momentary
mode, the scanner will prevent accidentally reading the same barcode twice by
using a
Re-read Delay (Blocking Time)
. The barcode must be taken away from the
scanning line longer than the
Re-read Delay
to allow second reading of the same
barcode. The user can set the
Re-read Delay
if necessary.
3.6 Scanner Time-out Duration
This parameter is used to limit the maximum scanning period when the scan mode
is either
Auto Off Mode
or
Auto Power Off Mode
. This time-out duration is
specified in units of second. The default time-out duration is ten seconds.
3.7 Reading Redundancy
This parameter is used to specify the levels of reading (decoding) security. If
No
Redundancy
is selected, only one successful decoding can make the reading valid.
If
Three
Times Redundancy
is selected, it will take 3 successful decodes to make
the reading valid. It is obvious that the more redundancy the user selects, the higher
the reading security and thus the slower the reading speed. The user must
compromise between decoding security and decoding speed if the security feature
is needed.
3.8 Supported Symbologies
Most of the popular barcode symbologies are supported. Each symbology can be
individually enabled or disabled. The scanner will automatically discriminate and
recognize all the symbologies that are enabled. The supported barcode symbologies
are listed below.

Code 39 (Standard / Full ASCII)
