Guidelines on

file data transfer

The PowerVisa treats the Compact Flash card like a hard disk storing files in DOS

format. For successful card data transfer, keep the following points in mind:

• PowerVisa supports a maximum DOS directory size of 128MB. Minimum required

Compact Flash data card size is 32MB.

• Compact Flash cards allow users to store multiple files in one card. The Site name

will be used as the filename for record files (i.e. if the site name is PowerVisa Site,

the filename will be PowerVisa Site 00.DDB). A number is automatically appended

to the name such that filenames are automatically incremented every time the user

starts monitoring with that same filename.

• PowerVisa does not support file fragmentation. When creating a file, it will take the

largest contiguous block and use that size block for data storage. Deleting files from

the memory card is NOT RECOMMENDED. When there is no more space available

to begin new data storage, reformat the card using the PowerVisa, after transferring

data files to a computer.
