Operator's guide
When you are done, click Configure instrument to submit the changes
to the digitizer and reboot it.
For full details on the configuration options available, see the documentation for
the DCM or the digitizer. You can also configure digitizers from within
Scream!, if you enable the DCM's Scream! server (see
“Real-time data
transmission” in Section 3.4
.)
Data storage and retrieval
All data received by the DCM is periodically written from Flash memory to the
on-board hard disk. The time period used can be configured from the Disk
menu of the DCM's Web site.
You can list the files on the hard disk
•
over the Web, by selecting Disk files from the menu, or
•
from the command line with
gfat32 ls
If you are using the Web page interface, each file appears as a link: simply click
its name to download the file.
Alternatively, you can remove the internal hard disk physically, and attach it to
any computer supporting either Firewire or the USB Mass Storage Protocol. It
will appear on the computer as an extra hard drive. The DCM uses a journalling
file system compatible with Windows' FAT32, so you cannot lose or corrupt
data by removing the hard disk, even if the DCM is in the middle of writing to
it.
