•  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. 

 

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.

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. 

 
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. 

 
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. 

 
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) 
•  Italy Pharmacode 
•  French Pharmacode 
•  Industrial 25 
•  Interleave 25 
•  Matrix 25 
•  Codabar (NW-7) 
•  UPCA (with or without Addon) 
•  UPCE (with or without Addon)
