possible when space available on the storage media is exhausted. Together with scheduled file closing, this option can be used to configure the SDR2-USB as a circular buffer— as the disk fills, the oldest file is overwritten.

//file name and path to record to Filename=DATA\GPS0000.txt

//create new files when recording starts Append=0

//buffer data when stopped FlushBuffer=0

//always record if media is present ForceRecording=1

//overwrite oldest file if necessary OverWriteOldest=1

4.1.4Scheduled File Closing Commands

Scheduled file closing, together with Append=0, allows the user to divide recorded data into files of a more manageable size.

FileClose (default=0): The FileClose setup file line enables and disables scheduled file closing.

FileCloseSeconds: The FileCloseSeconds setting configures the SDR2-USB to close the current file and restart recording after the specified number of seconds. For example, to configure the recorder to restart recording every hour, use FileCloseSeconds=3600 (3600 seconds=60 minutes=1 hour).

FileCloseBytes: The FileCloseBytes setup file line configures the recorder to close the current file and restart recording once the current file reaches the specified number of bytes. For example, use FileCloseBytes=1048576 to configure the SDR2-USB to create a new file if the size reaches 1 megabyte.

StartTime, StopTime: The StartTime and StopTime lines configure the recorder to start and stop at specific times of day (specified in 24-hour HH:MM:SS format). If start and stop times are equal, each file will contain 24 hours of data. FlushBuffer=1 (see above) is usually used if start and stop times are different in order to reject data received while recording was stopped.

//enable scheduled file closing FileClose=1

//record only during business hours StartTime=08:00:00 StopTime=17:00:00

FlushBuffer=1

4.1.5Time Stamping Commands

The SDR2-USB can insert time and date information into files during recording. Among other things, this is useful for scientific data analysis and historical trending studies.

Timestamp (default=0): The Timestamp setup file line enables date/time stamping.
