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.
