CMG-DM24
MBTRANSFER
Syntax: size MBTRANSFER
If a FireWire disk is plugged in to the DM24 when you are not running
DISKMENU, and there is enough new data in Flash memory, the DM24
will automatically transfer the new data to the disk.
The MBTRANSFER command sets how much new data there needs to
be before the DM24 will power up the disk and transfer it. If the disk is
left attached, the DM24 will then wait until it has collected the same
amount of data again before starting another transfer.
size is the amount of data to transfer, in megabytes; it must be greater
than 10 and less than the total quantity of Flash memory in the device.
Larger values will save power, because the disk needs to be accessed
less often.
If you plug a FireWire disk into the DM24 when there is less than
size Mb of data ready, no data will be transferred. If you need to
transfer smaller amounts of data, you should use the DISKMENU
system.
* The number of files stored on a disk is limited to 510. This may
prevent you from using the full capacity of the drive if the value of
MBTRANSFER is chosen to be particularly low. For example, a setting
of 10Mb for MBTRANSFER will limit the total quantity of data stored to
5.1Gbytes, regardless of the drive capacity.
DIR
Syntax: DIR (interactive)
Lists the files already present on a FireWire disk. When you issue this
command you will see the message
Plug in FireWire cable
and the DM24 will wait for you to plug in a compatible disk. When it
detects one, it will display information about the disk and list all the
files that it contains. Each time you use DISKMENU to download data,
or power on the digitizer with a FireWire disk connected (and enough
new data to trigger a download), a new file is created.
