By default, the CSV parser expects the following field sequence in the CSV files:

<Modification code>;<Unique ID>;<Barcode>;<Description>;...;...;...;...etc

Unique ID field:

Barcode field:

Description field:

Note: The optional barcode terminal displays the description when a link is created, so the user

can verify that the correct product was linked.

Note: The first field is field number "0", the second is "1", etc.

Note 2: When changing the field sequence of your database, make sure you delete the existing

product database files. (See section 1.3 for more information).

5.7.8 Image generator

The Image Generator is the executable of the middleware application that parses the product

database (dbase.csv) and the link database (linked.csv) into BMP and XML files for each

linked ESL. You can customize the layout of the generated images, and XML files themselves

by changing the image layout file (XML-based) and the XML template file.

The Image Layout is an XML-based layout file that determines the format of the images that

will be displayed on the ESLs. The layout file can only be manually edited using a text/XML

editor. This process is described in Appendix A.

The Info Template provides the formatting for the automatically-generated XML files for each

linked ESL. In most situations, this template can be left untouched. Only if the positions of the

unique ID or the product description arenʼt located at, respectively, field 1 and field 3 in the

CSV database, then these field numbers can easily be corrected. (See Appendix A).

The optional barcode terminal will be polling on the specified serial port for new ESL-product

links (link.csv) and will update the barcode terminal with the latest product database (scan.csv).
