Always Append to the File parameter
If you want the new receiver 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
result in closing the current log file. If data logging is off, pressing FN will
open a new log file.
• AFRM - If AFRM radio button has been selected, pressing FN will enable
this mode. If AFRM has been enabled, pressing FN will disable this mode.
Automatic File Rotation Mode (AFRM) parameters
JNS receivers are capable of automatically rotating log files. During a “file rota-
tion” event, the receiver 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 receiver 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 receiver 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
files in AFRM mode.
• 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 dec-
rements on every file rotation until it value becomes zero, then file rotation
automatically stops. The counter initializes with AFRM.
Note that a log file opens immediately after turning AFRM on. This startup file
is not considered a file rotation event; the AFRM counter will not decrement.
Values are 0 to [2
31
-1]. The default value is 0 (zero). Zero means that an unlim-
ited number of log files will be created.
