Appendix A: Database output formatting

The default output format of each record in the database file is:
<Barcode (40 chars)>,<Quantity (6 chars)>,<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
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 40 characters long,
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 6 characters long, but
this can be changed from 1 to 8 characters 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 not 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
OPN200x or otherwise formatted the RAM disk.
