Operator's guide
Once the data is stored on the DCM, whether in Flash memory or on the hard
disk, it can be retrieved
•
by a remote computer running Güralp Systems' Scream!, or other GCF-
compatible software;
•
by another DCM or AM, also using GCF;
•
by setting up a CD1.0 or CD1.1 transmitter on the DCM;
•
by direct file transfer (using SSH, HTTP, HTTPS, etc.,)
•
optionally, by requesting the data using SeedLink or AutoDRM.
A PC running Güralp Systems' Scream! software can not only collect data from
the DCM, but also configure the module and any instruments attached to it.
You may need to enable and configure some of these methods before you can
use them: see
Chapter 4, “Configuration options”
for more details.
Most installations of the DCM will not require any more complex setting up
than the Web configuration system can offer. However, in some cases you may
need to take advantage of the flexibility offered by the underlying Linux
operating system.
6.1 File systems
The DCM uses the standard Unix/Linux file naming conventions. The operating
system resides in two blocks of Flash memory, mounted on
/
and
/boot
;
when the module is powered up, a separate boot loader loads the rest of the
operating system.
