Table of Contents

All scanned unique barcodes are stored in a database file with fixed length records. Besides the barcode data, the quantity, serial number of the OPN and a date/

time stamp can be stored.

The default format of each record in the database file is:

Example:

8710841030181

8710841090246

9780131103627

The filename of the database is 'DATA.TXT', which is stored on the OPN. Depending on the selected interface, this file can be retrieved from the OPN as a file from

a Mass Storage Device or transferred by USB-VCP or CRD2000 using the NetO32 application.

When using the NetO32 application to retrieve the file, any transmitted data will be appended (by default), so all the data of multiple OPNs will end up in a single

database file on the local PC.

The resulting database file can be imported into various applications via a comma-separated (CSV) file.

To customize the output format of the database file, please see

If no quantity field is specified in the output format, then each bar code will be stored in a separate record.

This OPN firmware application uses the trigger button to enable the laser barcode scanner.

If a barcode is read using the trigger key, a good read beep is produced and a green LED is shown. The barcode is then stored in the database with a quantity of

'1'. If the same barcode is scanned again, the quantity is incremented by one each time.

To decrement the quantity of a barcode that is already in the database, the barcode should be scanned using the small delete key rather than the trigger key. A

short, good read beep is produced and an orange LED is shown.

If a barcode is scanned using the delete key that is not present in the database or that already has a quantity of '0', a low error beep is emitted and a red LED is

shown.

Negative quantities are, by default, not supported, but when using the 'Negative quantities' option (see

of barcodes. When a specific barcode has a negative quantity, the LED color changes from green (add) or orange (subtract) to red on a successful scan and the

sound becomes slightly lower.

It might become possible that your OPN has a full or corrupt RAM disk or contains unwanted barcode data that you want to delete from the OPN. In this situation,

it is possible to read the label below to erase all files from the RAM disk.*

Format

When using the OPN in USB-MSD mode, it is also possible to delete the file manually using a file browser.

* Note: If the OPN battery loses power, then the OPN will not immediately lose saved data. However, a few days afterwards, if the battery is not charged, all data

on the RAM disk will be lost. Also, the internal clock will reset if the battery is completely drained. The PC host application Appload (see Appload) can be used

to reset the correct date and time.
