12 Digital Storage Device (DSD)
12.1 Introduction
The indicator contains a Digital Storage Device (DSD) to record traceable readings. The DSD records the
following information about each entry:
The print ID
The weight reading
The tare weight
The date and time
12.2 Format and Capacity
The DSD is stored in a binary format internally. The DSD has a maximum size of 512 kilobytes, and can
contain approximately 11900 records. The indicator can be configured to either prompt the user to purge 10%
of records from the DSD, or automatically purge 10% of records, once the DSD is full. Records can also be
manually purged from the DSD from the DSD:PURGE setup menu.
12.3 Changelog Security
The DSD is stored on the internal indicator filesystem which is not accessible, and hence cannot be tampered
with. The indicator application is the only means by which to access the DSD. The indicator contains Alibi
software which allows the DSD records to be viewed. The Alibi DSD viewer is part of the trade approval.
When a USB disk is attached to the indicator, the DSD can be exported to the USB disk in a comma separated
value (CSV) file. CSV files can be easily viewed in most spreadsheet programs. This copy of the DSD can
always be verified against internal DSD, via the Alibi DSD viewer.
12.4 Configuring the DSD
The DSD is not enabled by default. To prepare the DSD for use:
Enter the full setup menus
Set DSD:ENABLE to On
Initialise the DSD with DSD:INIT
Configure DSD purging with A.PURGE
After this all traceable printouts will be recorded in the DSD
Note
Performing DSD:INIT will delete all existing DSD records.
12.5 Writing Records
A record will be stored in the DSD whenever a traceable weight is generated. A traceable weight is only
generated for a single, double or ticket printout. For more information on print setup see Section 5.5 and
Section 9. The DSD will also be written when a print occurs in alibi mode.
12.6 Reading Records
The records can be viewed in Alibi mode or exported to a USB disk in comma separated value (CSV) format
from the File menu (see Section 10). CSV files can be easily viewed in most spreadsheet programs. For more
information on viewing DSD records in Alibi mode see Section 13. DSD records exported in CSV format are
formatted as follows:
