Barcode Database File - Opticon RFI3793B Manual

4 Barcode database file

All scanned unique barcodes are stored in a database file with non-fixed length records. Besides the barcode data,
the quantity, serial number and a date/time stamp can be stored.
The default format of each record in the database file is:
<Barcode>,<Quantity>,<serial #>,<hh:mm:ss>,<dd/mm/yyyy>
Example:
8710841030181,12,003278,14:41:03,23/11/2009
8710841090246,2,003278,14:41:04,23/11/2009
9780131103627,1,003278,14:41:00,23/11/2009
The filename of the database is 'SCANNED.TXT', which is stored on the barcode readers.
The resulting database file can be imported into various applications as a comma-separated value (CSV) file.
When using the USB-VCP with OseComm or NetO to retrieve the barcode data, any transmitted data will be
appended (by default) to any previously retrieved barcode data on your host PC, so all data of one or more barcode
readers will end up in a single database file. The barcode file will be deleted from the barcode reader after successful
transmission.
When using USB-MSD you can manually retrieve or delete the database file 'SCANNED.TXT'.
Please note that when deleting this file in USB-MSD, also delete the local files 'SCANNED.TMP' and 'SCANNED.IDX'
from the disk as well. These other files are the files the barcode terminal actually uses, while 'SCANNED.TXT' is
merely an export from these files created upon connecting the scanner to USB. Editing 'SCANNED.TXT' while still
resident on the device's "drive" will have no effect. Editing 'SCANNED.TMP' will cause 'SCANNED.IDX' (search index-
file) to become corrupt.
To customize the output format of the database file, please refer to Appendix A.
If no quantity field is specified in the output format, then each barcode will be stored as a separate record.
