Appendix A: Database output formatting

The default output format of each record in the database file is:
<Barcode>,<serial #>,<hh:mm:ss>,<dd/mm/yyyy>
However, this application allows you to customize this format to make it suitable for your own application. The
following aspects of the output format are configurable. Read the configuration barcodes on the following page to
select the various options.
Date format
Time format
Field separator
Enable/disable
delete key *
Barcode field size
Quantity field size *
Delete record
if quantity=0
Negative quantities
allowed/not allowed
Field output sequence
* Hint: Disabling the delete key and quantity field increases storage capacity by 100%,
because no .idx-file and .tmp are created.
16 date formats are supported (see following page)
2 time formats are supported (hh:mm:ss and hh:mm)
The field separator is the character that is used to separate the various fields of a
database record.
7 different separators can be selected.
By default the small delete key can be used to remove a previously read barcode
from the database or reduce its quantity by 1.
By disabling the delete key this option can be disabled.
By default the barcode field size is variable length, but this can be changed
between 1 and 99 characters by reading 2 configuration labels on the following
page to specify both digits of the desired size.
By default the quantity field is variable length, but this can be changed from 1 to
9 digits if desired.
By default a record is deleted if a barcode in the database (with a quantity of 1)
is read using the delete key. However if you desire to keep a record of all delete
actions it is possible to leave the record with a quantity of '0' in the database by
disabling this option.
By default you can't delete a barcode that's not present in the database.
However for some purposes it can be useful to be able to read them anyway to
specify a negative quantity.
Each record can contain up to 5 fields (barcode, date, time, quantity and serial
number). The output sequence can be customized by reading up to 5 labels on
the following page.
By not specifying a quantity field each barcode will be stored separately in the
database. The database also will not be sorted and in case a barcode is read
using the delete key the last occurrence in the database will be deleted.
It is not allowed to not specify a barcode field in the output sequence.
Note: When changing the field sequence, make sure you've downloaded the
existing database file from the OPN/PX20 or otherwise formatted the RAM disk.
