Backup/Restore settings
Link IO has a USB micro port available just below the display.
You can either connect directly with a PC using a USB A (male) to USB micro (male) cable, or connect a USB
memory stick using a USB A (female) to USB micro (male) cable, also referred to as “OTG cable”.
When connecting with a PC, the Link IO main device is found as an external USB drive.
The USB memory stick would need to be formatted as FAT32 and it is recommended to use a USB2.0 dongle
with max 500mA current requirement. USB3.0 might not work because of higher current required to run.
All the settings (except the IP port settings) can be exported (
BACKUP DATA
) to a .txt file. The file can be
saved to:
-
LOCAL.
Saves the file on the root directory of the Link IO internal memory.
NOTE:
make sure there is
nothing (i
e PC) connected over USB when backing up or restoring data. A “memory error” message is
provided when trying to access the “LOCAL” memory with a PC connected
-
USB.
Saves the file on the root directory of a connected USB memory stick (USB 2.0 max).
This operation is very useful as the same file can be used on other Link IO main devices and restore
(
RESTORE DATA
) all the settings contained in the txt file within the Link IO, effectively reducing massively
configuration time for extended repeatable configurations.
The exported file can also be edited with the Web Configurator on our website! The Web configurator can
then save a new version of the txt file that can be used on the Link IO devices where needed.
Once the whole configuration has been made on this page, you will just need to get the cursor on top of the
“Confirm operation” setting displaying “NO”, and using the
buttons changing it to “YES” and press
to run the function.
Note
: the name of the file is particularly important. The file is always named as “EXPORT_xx.txt” where xx is
a configuration number between 0 and 99. The file name should always be formatted as required, with 1
digit between 0 and 9, and 2 digits between 10 and 99, so it can be found by the device when restoring a
configuration.
Examples of file name: EXPORT_0.txt, EXPORT_5.txt, EXPORT_67.txt
Using a wrong file name when restoring a configuration or backing up from/restoring to a USB memory stick
that is not recognized will fail the operation
showing “Cannot access file”.
Remember to always remove any PC USB connection when restoring from the local memory. While the PC is
connected the local flash memory will not be accessible by Link IO
and the error “Cannot access file” will also
appear.
