Introduction
The sunphotometer memory can contain at least a
day of measurements. To recover in a automatic way the data, without
any user intervention, a satellite transmitter is often used.
But how to get the data into a PC without any transmitter ?
It's possible (from the 4.70e sunphotometer firmware
version) to run a PC scenario in the user actions.

Setting up the instrument
You have to modify the actions list, so the instrument
know how to run the PC scenario.
Here is the way to add an "PC scenario"

Choose the ID number of action to run (Refer
to the sunphotometer documentation for the actions list)
in that case, the ID number of the PC transmission is the
fifteenth action (015). Validate the whole user action and
exit the edit mode by pushing on [G].

Setting up the PC
To have a successful transmission, ASTPWin must
be launched and the communication port must be opened. Refer to
the ASTPWin documentation for more details.
To launch ASTPWin everytime the PC start, create
a shortcut to ASTPWin in the Windows "startup" group and activate
the "automatic connection at the start" option in ASTPWin to open
the communication port automatically.
To automate the hard disk storing, go in the "Data"
tab of the "General setup" menu :
-
Activate the automatic recording in the chosen
directory. Every transmission will create a K7 file which
will be stored in that directory.
-
Select "Optimize transmission" the
transmit only the new scenarios.
-
You can also create automatically the ASCII
files but these files may be created later.
-
The sunphotometer must be in automatic
mode
-
The PC action must be planned between the
first and the last scenario of the day, all the actions planned
outside these limits will be ignored (for example, it's impossible
to run a scenario at midnight). The additional actions should
be ideally launched between 9h and 15h.
-
The used actions must be sorted in increasing
order to be launched correctly. Example : It's not allowed
to set the 2nd user action at 10h30 if the first user action
is planned at 11h30. In that case, the two actions must be
swapped.
