7.7 Storing Data on the Memory Card
7.7.1 Information on Saving Data on a Memory Card
You can save all the data collected from the Sunny Central to a memory card. The save-to-memory-card feature is
disabled by default on delivery.
If a memory card is inserted into the slot of the SC-COM and saving data to external storage media is enabled, the
SC-COM will copy all data from the internal ring buffer to the external SD card. The SC-COM stores new data on the
memory card for as long as the memory card is inserted in the slot.
The SC-COM creates a folder on the memory card. The name of the folder is "SC-COM_[SerialNumber]".
"[SerialNumber]" designates the serial number of the respective SC-COM. The SC-COM creates a new subfolder in the
main folder every day. Each subfolder contains all the data collected by the SC-COM. When the memory card has
reached its capacity, the H5 LED lights up red and the SC-COM stores no further data on the memory card. Replace the
memory card or reformat it on the computer. You can also read on the user interface, how full the memory card is
(see Section 7.8 "Determining Available Memory Space", page 34).
7.7.2 Inserting the Memory Card
2. Insert the memory card into the SC-COM slot.
7.7.3 Enabling and Disabling Data Storage on the Memory Card
1. Log in on the user interface.
2. Select Sunny Central > Settings > Security.
3. To enable saving of the data to the memory card, select Enabled in the field External memory.
4. To deactivate saving of the data on the memory card, select Disabled.
5. Select the button [Save].
Data loss when removing the memory card
Do not remove the memory card while the SC-COM is storing data on the memory card. This can damage the file
system of the memory card and lead to data loss. Depending on the amount of data, the writing process can take
some time.
