multiple read results. The master reader itself is also a slave that searches for 1D/2D codes in
the field of view.
Restrictions of the scanner portal application
The scanner portal application is subject to the following restrictions:
• All optical readers must operate in the untriggered image acquisition mode "Auto-trigger".
• If several different 1D/2D codes with identical contents are read one after the other, the
content is output only once.
• The master reader can only output the synchronized result via the TCP interface.
• The formatting options of the result string of the master reader are restricted.
• A maximum of five optical readers (4 slaves, 1 master) are supported.
• If a slave reader is in an error state, the master reader does not change to an error state.
• The master reader does not monitor the number of connected slave readers.
• Maximum results of 2048 characters including a formatting instruction required for
synchronization can be synchronized.
9.7.1 Configuration
The WBM configuration for the optical readers if you want to set up a scanner portal with
them is described below. A distinction is made between master device and slave devices for
the configuration.
Configuration of the master device
Make the following settings in the WBM for the master device:
• Menu: "Program > Image acquisition > Trigger"
To control the image acquisition, select the mode "Auto-trigger" (without "Initial trigger").
Make sure to enter the value "1" in the "Recognize double read" input box.
The acquisition interval must be sufficiently long for the 1D/2D codes in the image to be
read. The interval must be identical on all slave and master devices.
• Menu: "Program > Result > Program format text"
Enter the value "\02[CamId]\03%s\04" in the "Format text" input box.
– [CamId] can be selected freely and is used to identify the optical reader that read the
1/2D code in the field of view.
– The value "\02\03%s\04" is also allowed if no identification of the optical reader is
desired in the result output.
• Menu: "Settings > Communication > Interfaces > TCP"
– Enter the IP address of the TCP partner of the master device.
– Enter the port number of the TCP partner of the master device.
