CR10X Storage and Control Module
connected to the datalogger, which is of course the dominant situation, BUOY_METSTAT simply aborts instruction
96 and continues with the next line in the program.
Hence downloading data from the CR10X datalogger to the SM4M storage module is accomplished by simply
connecting the SM4M to the logger for minimal five minutes. However, to be positively sure that all data have been
transferred, it is advised to keep the storage module connected for at least 15 minutes.
Experienced users can manually invoke data transfer by using the star-eight mode on the keyboard display. To this
end, type in the following CR10KD keyboard instructions (for presentation purposes given between double quotes):
“*8” (to activate Manual Data Dump using the star-eight mode)
BUOY_METSTAT only uses Final Storage Area 1, and star-eight mode therefore automatically continues with
the selection of the output device. The display will show “01”. Type the following command:
“71” (this is the code for the SM4M storage module)
“A” (keyboard equivalent for ENTER)
The display shows a number. This is the Storage Module Pointer (SPTR), which represents the location up
to which data have been downloaded in previous dump sessions. As a default, this is the starting point for the next
data transfer exercise. To continue, type:
“A” (keyboard equivalent for ENTER)
The display shows a number; which is the address of the last occupied slot in the Final Storage Location,
containing the most recent measurement value. As above, it concerns a pointer and is called the Data Storage
Pointer (DSP). To continue, type:
“A” (keyboard equivalent for ENTER)
The display shows “04”. To start data transfer, type:
“1” (in fact, any number would do)
“A” (keyboard equivalent to ENTER)
After finalizing the data dump, the keyboard displays the number of the last occupied Final Storage
Location.
“Instruction 96”, as well as the above-presented “star-eight” mode, only transfers ‘fresh’ data from the logger to
the storage module, i.e. data that have not been down loaded before. In the majority of cases this is the appropriate
procedure. The trouble shooting section in this paragraph presents the instructions for transferring ‘old’ data to the
SM4M, i.e. data that have already been down loaded in a previous dump session.
2.4 Maintenance
The CR10X requires minimal maintenance. During the periodic inspection visits, the user should check that:
all sensor cables are connected to the wiring panel according to the wiring schedule presented in Annex 2 •
and Table 1;
the wiring panel is free of corrosion or other alien substances;•
the grounding cable between the instrument container/enclosure central grounding point and wiring panel is •
firmly connected;
the CR10X is firmly attached to the back plate in the protective enclosure/instrument container.•
