Appendix A. Campbell Scientific File Formats
A-6
A.3.4 IEEE8
A standard eight-byte floating-point number format used for certain values
within a record. This format consists of a single sign bit, an 11-bit exponent,
and a 52-bit mantissa.
A.4 Converting Binary File Formats
Campbell Scientific dataloggers not only use the previously mentioned binary
file formats but users may also choose to use and access these binary formats
on the PC. Binary files may be output as data files to the PC by RTDAQ to
save hard disk space or to accommodate a user who is only interested in using
binary files in an application. In addition, PC cards that are written by the
datalogger will contain binary files that can be accessed directly by the PC.
Binary files cannot be interpreted through mere visual inspection. Therefore,
binary file processing tools are available to read and convert these binary data
files to ASCII text. These conversion tools are Split and CardConvert. Refer
to earlier sections of this manual for complete information on Split and
CardConvert.
A.4.1 Split
Split has the capability of reading TOB1, TOB2, and TOB3 files and
displaying data from those files in ASCII format. The output parameters are
user specified and Split generates a file containing the converted ASCII format
values.
A.4.2 CardConvert
The CardConvert program can convert TOB1, TOB2, and TOB3 files to TOA5
file format or can convert TOA5 files to TOB1 file format.
