Serial (COM1):
As above but without SD-card in socket (number 2 and 9 do not apply).
Additional information’s for the using of SD-Cards:
The data files are stored on the SD-Card in the following tree structure:
D:\
Root-Directory
(here
drive
D)
sssss\
Subdirectory
(Station
name)
sssss
M
nn.TXT
Mean memory files (nn: 00..99)
sssss
E
nn.TXT
Extreme memory files (nn: 00..99)
Example station “MET23”:
“D:\MET23\MET23M00.TXT”
The data on a CD-Card is always written into the “00”-file. If a “00”-file is present in the subdirectory
the datalogger tries to append only the new data. Whenever the “00”-file is greater then ten million
bytes, the “00”-file is renamed to a not existing “01”- till “99”-file. Unless the renaming is possible,
the output of the data will be breaked.
Remarks:
The datalogger do not delete any data on the SD-Card.
The user is responsible to use a SD-Card with enough free memory and the
deleting of the old “01”- to “99”-files.
The write-protect tab of the SD-Card is not used by the datalogger.
We strongly recommend to backup the data on alternative media.
Do not eject the card while writing the data. Press the “ENTER”-Key for breaking
the output.
Liability is excluded for loss of data.
Refer to chapter 5.2 for recommended SD-Cards.
