IM MW180-01E
Explanation
Loadable Files
• Files transferred via FTP on the MW100 (.mxd extension).
• Data files are saved to the CF card using the MW100 (.mxd extension).
• Files saved after being joined and saved on the software (with the .mxc extension).
Display Range, File Size, and Number of Data Points of the Loadable Data
• 50 groups
• Maximum channels per group: 32
• File size: 2 GB
• Data points: 5 million
Note
• When loading a file of close to five million points, the error message “Insufficient Memory.
Close immediately.” appears. If this happens, set Total paging file size for all drives to 2 GB
or more. On Windows XP, this setting is located in the control panel by double-clicking the
System icon then choosing Details (tab) > Performance (setting button) > Details (tab) >
Virtual memory (Change button).
• Please avoid loading multiple files containing close to five million data points. Doing so may
degrade the PC performance greatly.
• Joining may take time depending on the number of data points in the divided files.
• Even when joining is performed, the files before joining (.MXD extension) are not deleted.
File Joining Function
Data saved to the CF card or transferred via FTP on the MW100 can be joined.
Files that are created using triggers cannot be joined.
• The data that can be joined are files measured or calculated and the thinning data files
by the MW100 that were created on the same unit from record start to record stop.
