LSI user guide
Synchronizing History
To synchronize LRU recorded logs you need a FAT32 formatted micro SD card with enough free space,
and the following folder structure:
●
Root folder named “LSI”,
●
Folder named “SYNC” within the “LSI” folder
●
Folder named “HIST” or “HIST#” within the “SYNC” folder
Note that the micro SD card used for logging can also be used for synchronization.
Right after power up the LSI will check to see if a folder named “HIST” or “HIST#” exists within the SYNC
folder, and if so activate the SYNC light to indicate that a synchronization operation is in progress.
During synchronization the recorded logs on each connected LRU are retrieved to a history file in the
HIST folder and then cleared on the LRU. On completion of this the SYNC light turns off and operation
resumes as normal.
Also at completion, should the HIST folder have been named “HIST”, the LSI will automatically rename
this folder to “#HIST”. The purpose of changing the name is to ensure that synchronization takes place
only once, and that the next time the LSI powers up no synchronization will be done. This necessitates
the user to actively rename the “#HIST” back to “HIST” (or “HIST#”) to enable another synchronization.
Note that with the HIST folder named “HIST#” synchronization will be performed at each power up
before resuming normal operation.
The LSI will create a new history file inside the HIST folder only if logs with a size larger than zero was
retrieved. Each history file is named MMMMSSSS_#.VRH where MMMM constitutes the LRU name (for
example “TSLM”), SSSS constitutes the LRU serial number, and # a unique number that automatically
increments every time.
To view any history file, open SetView and select File → Open History File... from the top menu. Then
browse to the history file you want to view and select Open.
