3.0 Operating the Unit
DAP-Imager can be used as a standalone application, or used in con-
junction with ScannerManager. In both cases, you will probably want
to leave the application hidden to wedge barcodes.
3.2.4.1
How to Scan Barcodes
To scan barcodes, first ensure DAP-Imager is in barcode mode. To do
that, open the application (double click the icon in the notification area)
and select
Barcode
from the mode menu.
The main window shows a preview and a text box with the results
scanned. At this point we can start scanning to test the capabilities.
Steps:
• Press and hold the trigger.
• Move the unit so that it is almost perpendicular to the barcode. The
barcode should fill 30% to 75% of the preview window, depending on
the density of the barcode.
• If the image is not on focus, move unit to force an automatic focus.
• It usually takes around 1 second to decode a barcode. On a successful
decode attempt, the barcode is surrounded by a green box and a single
beep is heard. Two beeps indicate failure.
Close DAP-Imager with the top right
X
button; the program remains in
background.
3.2.4.1.1
Using ScannerManager
Normally you will want to use ScannerManager, like in the following
screen:
ScannerManager configures DAP-Imager automatically and takes care
of the wedging.
When DAP-Imager is in background, it shows a live preview as long
as the trigger is held down. It helps ensuring the focus, position and
distance are correct. As soon as the barcode can be decoded, Scanner-
Manager receives the data and wedge it (if the output is set to Keyboard
Wedge).
3.2.4.1.2
Using DAP-Imager as a Stand-Alone Application
DAP-Imager can be used without ScannerManager. In that case, Scan-
nerManager must not be running, so that the trigger will be used exclu-
sively for DAP-Imager.
NOTE:
If you have used ScannerManager before, the keyboard wedge
will have been disabled. To enable it, turn “KbWedge”
ON
in
the INI file. Check the “.INI Configuration File” section for
more information.
You can scan barcodes the same way it’s done in ScannerManager even
if using DAP-Imager separately.
3.2.4.2
Decoder Configuration
The
Symbols
button shows the decoder properties configuration
screen. It allows enabling or disabling specific barcode types and set-
ting advanced parameters.
Double click on an item to change its value. If it’s an ON/OFF value, the
change is applied immediately. For other value types, set the value in
the “Value” field, and then click on
Apply
.
An asterisk (*) indicates default values.
Enabling all barcode types will make decoding slower. You may start
the configuration by selecting a preset (
Presets
button).
The
Options
button pops up the Decoder Options screen.
These parameters should not be changed, except if suggested by a DAP
technical support representative.
3.2.5
.INI Configuration File
DAP-Imager uses a .INI configuration file located, by default, in
C:\ProgramData\DAP-Imager\DAP-Imager.ini
Before changing it, you must unload DAP-Imager by clicking its icon
in the notification area and choosing
Quit
. Otherwise, the program
rewrites the INI file when it quits.
If no DAP-Imager.ini file is found in the directory, a new one is auto-
matically created with default values.
