3.6 Scanner Time-out Duration
continue to scan and the scanning period is re-counted each time there is a
successful read.
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.
• Alternate Mode: The scanner will start scanning once the switch is
triggered. The scanner will continue scanning until the switch is triggered
again.
3.7 Reading Redundancy
• Momentary Mode: The scanner will be scanning as long as the switch is
depressed.
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.
• 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.
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.
• Laser Mode: This is the scan mode most often used on laser scanners. The
scanner will start scanning once the switch is pressed. The scanning
continues until either a barcode is read, the switch is released or a preset
scanning period (Scanner Time-Out Duration) is expired.
• Code 39 (Standard / Full ASCII)
• Test Mode: The scanner is always scanning. The scanner will decode
repeatedly even with the same barcode.
• Italy Pharmacode
• French Pharmacode
• Industrial 25
By default, the scan mode is Auto Off mode for scanners with trigger switch, and is
Continuous mode for switch-less scanners.
• Interleave 25
• Matrix 25
3.4 Auto-Sense
• Codabar (NW-7)
• UPCA (with or without Addon)
Auto-Sense is 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.
• UPCE (with or without Addon)
• EAN8 (with or without Addon)
• EAN13 (with or without Addon)
• Code 93
• Code 128
3.5 Re-read Delay
• EAN 128
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 Re-read Delay can be set by the user.

• Telepen
• Plessey
3.9 Negative Barcodes
The scanner can be configured to read negative barcodes. Normally, barcodes are
printed with the color of the bars darker than that of the spaces. But for negative
