Installation, Operation and Maintainance of Buoy Operated Automatic Meteorological Stations
CR10X Storage and Control Module
“DDDD” (enter Julian Day; See Prompt Sheet to transfer calendar days to Julian days)
“A” (keyboard equivalent to ENTER)
“HHMM” (hour and minute)
“A” (keyboard equivalent to ENTER)
The last step in the installation process is protecting the system against unauthorized user interventions. For this
purpose a password is introduced, which blocks access to (a) modifying the active datalogger program, (b) loading
new programs, and (c) changing the memory allocations.
To enter a password, type in the following commands (given between double quotes for presentation purposes):
“*C” (activates C mode)
“2000” (the proposed default password for all dataloggers)
“A” (keyboard equivalent of ENTER)
Box 3: Temporarily De-activate Security
Security needs to be temporarily disabled when the user wants to reload METSTAT. To this end, type the
following commands on the CR10KD (for presentation purposes given between double quotes):
“*C” (activates C mode)
“2000” (the proposed default password for all dataloggers)
“A” (keyboard equivalent of ENTER)
On entering “*0” security is automatically re-enabled.
This completes the installation process, and the datalogger should now be operational and executing the periodic
measurements according to the instructions encoded in BUOY_METSTAT.
The user can check the initial performance of the system by entering ‘star-six’ mode. This mode displays the
input storage values, which represent the ‘fresh’ measurements. Annex 3 presents the respective input locations
per variable used by BUOY_METSTAT. The user can check if these values are within the expected range, and
corresponding to the present weather conditions. Use “A” to advance to the next input location, and “B” to return to
the previous one. Please note that BUOY_METSTAT has an execution interval of 300 seconds. Hence the values shown
in star-six mode do not represent the instant weather conditions.
If all values are within a satisfactory range, disconnect keyboard display and storage module. Installation of the
CR10X is now completed.
Paragraph 2.6 presents a Prompt Sheet, which serves as a memory aid while in the field. It contains a comprehensive
overview of relevant keyboard commands.
2.3 Use
The operation of the CR10X does not require any additional actions of the user once successfully installed. Sensor
activation, measurements, initial data processing, and data storage are all fully automatic, according to the
instructions given in BUOY_METSTAT.
BUOY_METSTAT includes a routine called ‘instruction 96’. This instruction checks every 5 minutes if the SM4M
storage module is connected to the system. If this is the case, BUOY_METSTAT automatically initiates data transfer
from the logger’s Final Storage Areas to the SM4M. No further user interactions are needed. If the SM4M is not
