Dataman 48UXP - Manual (Page 27)

To Buffer Address
Starting address of the buffer to load the file into, if the data
read is to be copy into a specific area of the buffer, fill in the
starting address here.
Size
This box contains the buffer size. By default, it is the same
size as the device selection in the Dataman-48UXP screen. If
you want to download a file into memory that is bigger than
the active device, insert the size here (or in Options |
Operation Options).
Clear Buffer Options
Four options are available during memory buffer data
loading. The default option is to clear the buffer to its blank
state prior to data loading.
Disable
This option leaves the original buffer data unchanged, but
then overwrites it with the contents of the newly loaded
file.
Blank state
This option clears the buffer to the device blank state,
(using command 00 or FF, depending on device selection),
then overwrites the buffer during file loading.
0x00
First clears the buffer of its contents using command 00,
then over-writes the buffer with the new file contents
0xFF
First clears the buffer of its contents using command FF,
then over-writes the buffer with the new file contents.
