OPERATION
Downloading and Analyzing the Data
For technical performance reasons, the Slam Stick?
stores its data in a raw binary format, which requires
additional software to interpret or convert to a more
accessible format. There are currently two ways to do
this: use a standalone PC/Windows program, or use
the Matlab scripts (preferred if available) to view the
data graphically.
Viewing Data and Analysis Using Slam
Stick Viewer
Slam Stick Viewer is a GUI application for viewing and
exporting data from the Slam Stick?portable vibration
recorder and configuring the recorder. It’s written in the
Python programming language, and can be used either
stand-alone, as part of your own data analysis s
scripts, or interactively with SciPy’s IPython shell.

PLEASE NOTE: The data.dat file (approx. 4Mbytes)
and config.dat file will always appear on the device,
even if it has been “erased” and no new recordings
have been taken. Because date and time information
is not available to the Slam Stick?, the file
timestamps will contain a default value (e.g.
1/1/2000) regardless of the date the recording was
taken. This is normal operation, and not a cause for
concern.
Do not perform file management directly on the
Slam Stick? (such as deleting, moving or creating
new files on the device, or reformatting) using your
PC, as this may cause any currently recorded data
to be lost. If such file management has been
performed, or your PC does not correctly recognize
the disk, please erase it by holding down the button
while unplugging. This will recreate the internal file
Exporting data to spreadsheet (.CSV)
format using ss2csv.exe
For Windows users*, the included ss2csv.exe program
can be used to convert recording files from the
vibration recorder ’s native format to a plaintext .CSV
(Comma Separated Value) file that can be used with
many common software packages.
PLEASE NOTE: MS-EXCEL or OpenOffice will not
completely read a .CSV file which contains more
than 65,535 lines (approx. 20 seconds of data at
3200Hz). If such a file is opened, only the first
65,535 lines will be read. This is a limitation of MS
(and compatible) spreadsheet software.
If more than a quick 20-second preview is needed, other
software/script language must be used to plot the data.
system and associated files.
* Users of other operating systems, please refer to
To download a permanent copy of the recording data,
plug the device into a USB port and copy the data.dat
file to a desired location. You can rename it with a
more descriptive name if desired.
If it is not important to save the data permanently, you
can instead point your analysis software at the data file
on the device, rather than copy it to your hard disk.
Please note that reading from the USB stick is much
slower than reading from your hard disk, so the
analysis software may take some time to finish reading
the file.
section non-windows platforms for information on
building the included source code on other platforms.
Interactive mode (prompt for user input)
To run the program interactively, run ss2csv by double-
clicking on its icon. When prompted, enter the path and
filename of the data file to be converted (if the data file
is in the same directory as the program, only the
filename needs to be entered). The recordings will be
output as files named VIB0000.CSV, VIB0001.CSV,
etc., in the directory the program was run from, one file
per recording. The output files will always be numbered
in the order they were recorded.
