Remarks on program function

The data for configuration of a virtual scanner can be updated, i.e. created, changed or deleted, with the program. Data which has already been stored can also be displayed.

The interface and link to an interface, processing unit should be defined and the device-specific operating mode of the device set.

Note:

Virtual devices are only intended for test purposes if connection of devices is not possible for whatever reason. Java 1.4 or newer versions should be installed if virtual devices (printer, display, drawer, lock or scanner) are to be tested.

A device interface type IP address should be configured and the device name, the local IP no. (localhost) and the port no. (5440) (locahost:5440) entered. In this example 5449 should be used as port no. for the virtual scanner.

The EAN-Code can be entered in the program window and can be scanned via the button "Scan". All entered EAN-Codes will be stored temporary und can be selected again from the select list. An XML file (scanCodes.xml) can be stored in the ..\work directory to keep the EAN codes. The file "scanCodes.xml" will be read during the start procedure of the virtual scanner.

Example "scanCodes.xml":

<?xml version='1.0' encoding='UTF-8'?>

<scanCodes>

            <scanCode value="500153"/>

            <scanCode value="40304069"/>

            <scanCode value="400476427145"/>

            <scanCode value="4001257153002"/>

            <scanCode value="4004764827145"/>

            <scanCode value="4006508125425"/>

            <scanCode value="4011800500153"/>

            <scanCode value="4015000011433"/>

            <scanCode value="4051400808105"/>

            <scanCode value="4311596402519"/>

            <scanCode value="9783860631621"/>

<scanCode value="42048060"/>

</scanCodes>

Remarks on data fields

All options available for update of the basic data have been described below.

As with nearly all programs the following also applies here:

• The entry mask in the application program may differ for this program. Some data fields may be missing
• There may be some defaults or firmly defined selection options for some data fields. These cannot be updated in the current program.
• The entry mask contains fields where entry is optional and fields with enforced entry defined.
• If the data record is updated over several pages of entry masks, the dialog window is reached by clicking onto the appropriate button with <Mouse key 1>.
• The same procedure also applies to call-up of another update program from this program.
• In some cases, you may find so-called "Switches" which are activated or deactivated by the user with <Mouse key 1> depending on the setting. Activated switches have a dark top, deactivated switches are lighter..

Debug

Field with firmly defined selection options

Select one of the debug levels offered by clicking on this field and with a second click confirming the option selected.

The system offers the following:

• 0 = no protocol of data communication in file "errlog"
• 1 =
• 2 = all communication data in file "errlog"

Notes:
Only select a value higher than "0" for the debug level if a protocol of the communication of the device is required for error analysis.

Port number

Entry range permitted: numeric, 1 - 99999

Enter the port no. of the virtual scanner.

Example:
Entry "localhost:5440" stands for the interface type IP address. Port no. 5449 should be entered for the virtual scanner.
