other disk. In most cases, however, it will be necessary to convert the file
format before using the data.
It is usually better to format the card, after the data has been retrieved from
it, prior to inserting it back into the logger. This will insure that memory is
available on the Card for the program to create the File structure for its
requisite Data Tables.
2.3.5 Converting File Format
The CR9000X stores data on its CPU and on PC cards in a TOB3 Format.
TOB3 is a binary format that incorporates features to improve reliability of
the data storage. TOB3 allows the accurate determination of each record’s
time without the space required for individual time stamps.
This raw TOB3 format is the only format that includes any FileMarks that
have been written to the Tables. When converting the data table, it can be
separated out into multiple data files based on the location of these file
marks. If is desire to utilize FileMarks, it must be done using the raw
TOB3 file, either using a file from the Card, or a file that has been
retrieved using the File Control window.
See the FileMark topic in Section 9.1, Program Structure/Control.
FIGURE 2.3-3. File Conversion dialog box
RTDAQ’s file converter will convert TOB1 binary files to ASCII, array
compatible CSV, or CSIXML files. It can convert TOB3 binary files to all
of these plus to the TOB1 file format.
The Convert Data Files utility is under RTDAQ's Tools menu. Data can
be converted with or without Time Stamps and/or Record Numbers.
