The file name depends on both the file creation time (month and day) and
additional letter suffixes to avoid confusion between files created on the
same day.
Always Append to the File parameter
If you want the new board data to be appended to an existing log file, enter
the desired filename in this parameter. The setting can be up to 20 characters
long.
Files Creation Mode parameter
This parameter has two possible operation modes:
• Log file - If this radio button has been selected, pressing the FN key will
• AFRM - If AFRM radio button has been selected, pressing FN will enable
Automatic File Rotation Mode (AFRM) parameters
JNS boards are capable of automatically rotating log files. During a "file
rotation" event, the board closes the current file and opens a new one
according to a user-defined schedule. The Period and Phase parameters
specify this schedule. File rotation launches the moment the board time
module Period is equal to Phase. More precisely, a new log file opens
immediately before the scheduled epoch causing data tagged with this epoch
to be recorded to the new log file.
When opening a new log file, the board enables the default set of messages
outputted with the default output period. Both the default set of messages and
the default output period are programmable.
• Period - specifies the time duration of each log file created in AFRM mode.
• Values are 60 to 86400 seconds. The default value is 3600 seconds.
• Phase - specifies the "phase" (constant time shift) of creating multiple log
• Values are 0 to 86400 seconds. The default value is zero seconds.
• Files (total) - a counter that specifies how many multiple log files must be

created in AFRM until this mode automatically turns off. This counter
decrements on every file rotation until it value becomes zero, then file
rotation automatically stops. The counter initializes with AFRM.
