Guralp Systems CMG-DCM build <10,000 - Manual (Page 153)

Acquisition Modules and Platinum Firmware Recording and Retrieving Data
powered up until you exit the shell (with the exit command or by keying
+ ).
The “format” option, which can be selected with the key, prepares a drive
for use, as described in section 11.1 on page 137.
When using shell scripts, all of these menu functions can be accessed by
passing the function name as an argument to Pt­storage. For example:
eam999 ~ # Pt-storage --mount
performs the same function as selecting ”mount” from the Pt-storage menu.
Note: Older removable hard-drives had internal heaters and
temperature sensors. It can take several seconds to pre-heat and
power up one of these drives. Be prepared for short delays when
using some of the following commands with these drives.
Once the mass storage device is powered up and the relevant file-system
mounted, the recorded files can be browsed with standard Linux shell
commands such as cd and ls. They can be copied to a remote PC using the
network or over the serial port (as described in section 11.3.1.4 on page 157).
To copy files over the network, the use of scp or rsync is recommended. The
scp program is most convenient to use and can copy single files or recursively
copy directories. The rsync program is more complicated but is ideal when a
remote copy of the data is to be updated regularly, since it minimises the
traffic over the network by only copying new or changed files. The same
rsync syntax can be reused regardless of changing filenames.
For Linux users, scp is installed by default or available as an optional package
in most distributions. Consult your operating system documentation for more
details. For Windows users, the WinSCP package is recommended: this has
the additional benefit of providing a graphical, explorer-like interface for
browsing files on the acquisition module. WinSCP can be downloaded for
free from
http://winscp.net .
The screen-grab below shows a complete session recorded from a Linux PC.
The operator connects to a acquisition module, powers up the mass storage
devices, downloads all recorded files, powers down the mass storage devices
and then disconnects.
