Middleware Application (Csv-Files Only) - Opticon ESL Server Manual

Middleware application (CSV-files only)

Note: By default the use of a middleware application is disabled ('CSV-parser' field in the 'Data'-
tab is empty).
The ESL server application can use a middleware application to process the CSV-files from the
Back office into a combined CSV-file that the ESL server application uses.
The tasks of the CSV-parser are:
 Parse product database files (modification or complete databases) into a combined CSV-
database containing all product info.
 Parse product-ESL link files (modification or complete databases) into a combined CSV-
database containing all product-ESL links.
 (Optional) Generate a reduced article database (CSV-format) for the barcode terminal.
 (Optional) Verify price formatting and calculate the discount percentage
To process a product database, the ESL server manager will call the CSV-parser with the
following parameters as specified in the setup window of the ESL server application:
<CSV-parser>.exe –O<Output folder> -I<Image folder>
-i<Id field> -b<Barcode field> -d<Description field>
-f<From price field> -s<Sell price field>
-p<discount percentage field> -F<Field separator>
-D<Decimal symbol>
-Z<Display leading zero setting> (-Z –Z- or -Z0>
-T<Create barcode terminal file (scan.csv)>
<Database file>.csv
So the default call by the ESL server application would be:
EGF3709x.exe -O"Output" -I"Output\Images" -i1 -b2 -d3 -f5 -s6 -p7 -F; -D. -Z0
"Input\ExampleData.csv"
To process a product-ESL link database, the ESL server manager will call the CSV-parser with
the following parameters as specified in the setup window of the ESL server application:
<CSV-parser>.exe –O<Output folder> -i<Id field> <*link*>.csv
So the default call by the ESL server application would be:
EGF3709x.exe -O"Output" -i1 "Input\Linked.csv"
If used, the record format of the truncated database file (scan.csv) for the bar code terminal that is
generated will have the following format:
<Barcode>;<Unique ID>;<Description (optional)>
If no barcodes are used in your application or when the Unique ID is the barcode, then the
'Barcode'-field will be the same as the 'Unique ID'-field.
