Auto Record uploaded streams tells Scream! to record streams it
receives over the network. These are not normally counted with the
streams above, since they may come from another Scream! which is
already recording.
Auto-upload on heartbeat tells Scream! to attempt to fetch extra data
from digitisers which are storing it in their own Flash memory
whenever possible, so that it can fill in gaps in the data it is recording.
The DM24S12AMS's built-in digitisers do not have any internal Flash
memory, so this option will only have an effect for digital instruments
connected to the DIGITAL A – F ports.
The lower section tells Scream! how to use its hard disk space. If Stop on
Disk Full is selected, then Scream! will stop recording data once it runs
out of space in its directory. This way, the data recorded will have a
known starting point. If you select Ring Buffer, then Scream! will start
deleting the oldest files in the data directory in order to make space for
new data, so that you will always have access to the most recent
recorded measurements. Note that Scream! does not check whether it
created the files itself. If you put your own files in Scream!'s data
directory, then they are at risk of being deleted.
If there is very little space on the disk, the PC's operating system can
become slow or unstable. By default, Scream! will consider the disk
