Check disk filesystem
Clicking on this button will verify the integrity of the hard disk's
filesystem. It is recommended that you do this immediately after
installing the device.
Flush flash
Clicking on this button will cause the DCM to dump the current
contents of its Flash memory to the hard disk, thus synchronizing it
with the most current data. If you want to remove or replace the DCM's
hard disk, using this tool will ensure that the outgoing disk is up-to-
date.
Flush flash does not remove data from the DCM's on-board Flash
memory. If you Flush flash and then swap hard disks, the data
remaining in memory will later be written out to the new hard disk,
causing some overlap between it and the old disk.
Whilst the DCM is copying the contents of the Flash memory to disk,
you will be shown a log of its progress. The USB interface allows data
transfer at a speed of around 100 Kb/s, so large files may take several
minutes to complete. If an error occurs at any point, it will be marked
in red.
4.8 Camera
If you have attached a compatible camera to the external USB port of
the DCM, clicking on this link will show the current view from the
installation site. A new image is retrieved every 12 seconds, or
whenever you reload the page. Güralp Systems can supply a
compatible camera with the DCM, although any STV0680-based
device can be used.
