Section 8. Recorder Data Extraction (SONREC.EXE)
SONREC extracts data from the optional internal recorder to a computer disk. To learn about its
operation, type
SONREC at the DOS prompt. The command syntax is:
SONREC [com port] [baud rate] [extraction rate]
where
•
[com port] is the serial port to which the ADV is connected (1 for COM1; 2 for COM2).
•
[baud rate] is the communication baud rate setting of the ADV (default is 9600 baud).
•
[extraction rate] is the baud rate at which data files will be retrieved from the recorder
(default is 115200 baud).
For short cables, the default extraction rate of 115200 baud provides the fastest downloading
time (about 4800 bytes per second). For longer cables, you may need to use a slower baud rate to
ensure reliable communication. If the program encounters errors while retrieving data, it will
terminate the retrieval.
Upon execution,
SONREC wakes the ADV and establishes a direct link to the recorder at the ex-
traction rate.
SONREC then downloads a directory of the files stored on the recorder, which may
take a few seconds. After the directory has been downloaded,
SONREC shows a list of files cur-
rently stored on the recorder. The directory screen presents the following information.
• Number of files on recorder
• List of files including name, size, and date/time of creation
• Recorder size (bytes)
• Recorder free space (bytes)
• Baud rate used for data extraction
• Active keys and their function, as listed below
ESC - exit program
SPACE BAR - mark and unmark files for extraction
F3 - retrieve all marked files
DEL - format the recorder and erase all data
Use the up/down arrow keys or PgUp/PgDn keys to move between files. The space bar will mark
and unmark one or more files for retrieval. Pressing F3 retrieves all marked files.
SONREC
prompts you to enter a destination path for the files; if no path is given, the current directory is
used. While retrieving data files,
SONREC displays its progress.
Pressing <Del> will format the recorder and delete all data files. Before the files are deleted, you
are prompted to enter the complete word “Yes” for confirmation. Be certain that all data are
backed up before erasing the recorder. Data cannot be recovered after formatting the recorder.
Pressing <Esc> will exit the program.
Data files extracted from the ADVField internal recorder are automatically assigned the
extension
.ADR .
