Table 3.5 Binary Archive Filenames
3.6.2 Binary Format Channel Data Files
A new channel data binary file is created under the following
conditions:
•
When the current file for a channel does not exist on the
media card.
•
When the maximum size (5Mb) of the existing data file is
exceeded.
•
When the recording channel's configuration is changed.
•
When the daylight saving period starts or ends.
Files containing channel data generated during the daylight
saving period (summertime) have "~DS" appended to the
filename.
– Start of daylight saving period:
Example 1
Archiving is started at 01:45:00 on 30
filename: 01450030Mar03Ch1_1AnlgSM2000.B00.
Summertime starts at 2:00am on 30
The
clock
changes
The existing file is closed and a new file is created –
filename: 03000030Mar03Ch1_1AnlgSM2000~DS.B00.
The
file
'01450330Mar03Ch1_1AnlgSM2000.B00'
contains data generated from 01:45:00 to 01:59:59 (before
summertime starts).
The
file
'03000030Mar03Ch1_1AnlgSM2000~DS.B00'
contains data generated from 03:00:00 (after summertime
starts).

3.6.3 Binary Format Log files
A new binary log file is created under the following conditions:
•
When an existing valid binary log file does not exist on the
media card.
•
When the maximum size (64000 entries) is exceeded.
•
When the daylight saving period starts or ends.
Files containing log data generated during the daylight saving
period (summertime) have "~DS" appended to the filename.
3.6.4 Binary Format
Data File Examples – Figs. 3.8 to 3.11
Binary format archived data is stored in a secure binary encoded
format. A separate file is created for each recording channel. The
log data is stored in an encrypted text format. The files can be
read on a PC using the Company's DataManager software
package.
3.6.5 Binary Format Data Verification and Integrity
When data is saved to the archive media it is checked
automatically to verify that the data stored on the media matches
exactly what is stored in the internal memory.
Each block of data in the channel data files has its own data
integrity check. This enables the integrity of the data stored on
the external media card to be verified when it is viewed using the
DataManager Review software package.
The log files also contain built-in integrity checks enabling the
integrity of the data to be verified by the DataManager software.
