Telemetry Data Storage option.
WARNING : launching a new storage will erase the previous storage files. Do not forget to save them.
For each telemetry channel (generally 3) a storage area is allocated on the disk organized as a FIFO structure.
Modification of the storage capacity will impact the maximum number of files and file size
Telemetry frames or blocks of raw data (or dummy frames if the telemetry chain is unlocked) are stored on the
disk (default files : D:\ZDS\Data\TmRecorder\Tmu
N being the number of files in the storage area) under the form of telemetry messages as specified in
STI100013_rtr_ng. Telemetry data are binary-coded. The file name and access path can be changed in the
Windows registry.

Telemetry storage can be Activated/Inhibited by a Control Client. Once the storage function has been activated,
the following commands are available:
Select the first file to write (1 is the identifier of the first file in the storage area),
Program the « stop writing » conditions (see below),
Start writing data to the selected file,
Stop writing data,
Resume writing data, from the current position in the storage area.
The identifier of the current file as well as the position of the write pointer in the file is available in each TMU
monitoring table.
The « stop writing » conditions are:
Stop on reception of a « Stop writing » command,
Stop when the programmed number of files has been written. This number of files is less or equal to the number of
files of the storage area.
The file FTMU in each TMU repository (D:\ZDS\Data\TmRecorder\TMUx, x= A..F) contains information about the
records FTMUn, n=1..N.
While FTMU is an ASCII file, it should not be modified by any other mean than the signal processing software
provided with Cortex units. For consistency, FTMUn files should not be deleted/modified either, except in the case
of a full clean-up of the repository.
