Technical operation
50% full. If you prefer, you can configure the DCM to write to the hard disk at
set intervals.
Writing to the hard disk is performed robustly, so that no data will be lost if a
write is aborted. This means that you can safely swap hardware in and out at
any time. Stand-alone DCM modules use off-the-shelf Lacie hard disks,
which can be easily removed and installed in most conditions. You can
specify other models of IDE / USB or IEEE 1394 2.5” disk at manufacture. If
an internal disk is not present, and the module has a USB host interface, it
will look for hard disks connected to its external USB port.
Once the data are 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;
•
Another DCM or AM, also using GCF;
•
Setting up a CD1.0 or CD1.1 transmitter on the DCM;
•
Direct file transfer (using SSH, HTTP, HTTPS, etc.,)
•
Optionally 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.
