Using the Gryphon D432/412Plus
16 Gryphon™ D432/D412Plus
Autoscanning
Normal Mode
Gryphon D432/D412Plus provides an autoscan command (see page 78), which when enabled,
causes the reader to scan continuously and to monitor th
e central zone of its reading area. In this
way, Gryphon D432/D412Plus is ready to capture any image (containing a potential code)
positioned on a
uniform background.
The aiming system can be enabled to indicate the reading area of the potential code to be
captured. The
illumination system can also be enabled when the ambient light conditions are
not sufficient to autodetect the potential code to be captured; furthermore, the illumination
system increases in intensity for an instant when capturing and decoding an image. A safety time
may be defined to prevent Gryphon D432/D412Plus from reading the same code repeatedly.
If the decoding is completed successfully, the reader starts monitoring the reading area again. In
case of
decoding failure, Gryphon D432/D412Plus keeps on decoding until a potential code is
present in the central zone of the reading area.
Pattern Mode
The Autoscan pattern mode is particularly advised when reading barcodes positioned on a non-
uniform background. In these cases Gryphon D432/D412Plus may perceive some elements of
the background as barcodes and start the decoding. To avoid this undesired effect, the Autoscan
Pattern Code is placed in the Gryphon D432/D412Plus reading area which prevents decoding.
Using this code as the background, code reading takes place normally by presenting desired
codes to be read over the Pattern Code. Between each code read, the Pattern Code must be
presented to the reader.
The Pattern Code can be printed from this manual (see Appendix D).
In case of low ambient light conditions, Gryphon D432/D412Plus automatically activates the
illuminat
ion system. If desired, the illumination system can be enabled so that it is always active.
Defining Data Formatting
The string of a decoded code to be sent to the host may be formatted as follows:
• defining simple data formatting (see page 48);
• defining advanced data formatting giving complete flexibility in changing the format of
data (see "Advanced Data Format"on page 91).
When both simple and advanced data formatting
are selected the info is processed in the
following order:
1. The string of the decoded code is processed acc
ording to the advanced formatting rules;
2. The resulting string is processed according to th
e selection type rules of the simple data
formatting;
3. Character substitution is performed on the resulting string;
4. Character deletion is performed on the
resulting string;
5. Code concatenation is performed;
