Data Retrieval, Processing and Final Storage in the Nile Basin Database
PC208W Datalogger Support Software
If the user has opted for the Recommended Directory Structure (see paragraph 4.2), data files captured from the
SM4M should be stored in the following folder:
C:\CAMPBELL\FILES\INPUT
Step B6: Click the “Get New” button. This option collects all “new” data files from the SM192, i.e. all files not
yet retrieved from the storage module in a previous down load operation. Each single SM4M data file is stored in an
individual DAT file on the hard drive.
For ease of reference, the above presented steps are listed in Annex 2.
5.2.4 Pointers
The Module Pointers area of the Status Box lists four different parameters, i.e. Free Space, Storage Ref. Pointer,
Display Pointer and Dump Pointer. Each of which is briefly discussed below.
Free Space: As implicated by its name, Free Space concerns the number of free data locations in the SM4M.
Storage Ref. Pointer: The Storage Reference Pointer (SRP) points to the SM4M location where the next data value
will be written.
Display Pointer: The Display Pointer points to the location which holds the first value which will be output in
response to the ‘Get One’ or ‘Get New’ data button in the Data Control Section of the software.
The pointer can be set to any desired location by using the Display Pointer position box in the Advanced section
of the data control status box, either by typing in the required location or clicking on the green arrow to move the
pointer to successive filemarks. This option is used to re-down load data from the SM4M which has already been
retrieved in a previous operation. This can be useful in case of data loss.
