frequently open and close a serial port, the probability is higher that a non-PakBus
character will arrive at the closed serial port, thus closing an existing talk-through
or comms watch session. If this occurs, the FileManager() setting to send comms
watch or sniffer to a file is immune to this problem.
10.11 Logs
Logs are meta data, usually about datalogger or software function. Logs, when
enabled, are available at the locations listed in the following table.

10.12 Troubleshooting — Data Recovery
In rare circumstances, exceptional efforts may be required to recover data that are
otherwise lost to conventional data-collection methods. Circumstances may
include the following:
• Program control error
o A CRBasic program was sent to the CR1000 without specifying that it
run on power-up. This is most likely to occur only while using the
Compile, Save and Send feature of older versions of CRBasic Editor.
o A new program (even the same program) was inadvertently sent to the
CR1000 through the Connect client or Set Up client in LoggerNet.
o The program was stopped through datalogger support software File
Control or LoggerLink software.
• The CPU: drive was inadvertently formated.
• A network peripheral (NL115, NL120, NL200, or NL240) was added to the
CR1000 when there was previously no network peripheral, and so forced the
CR1000 to reallocate memory.
• A hardware failure, such as memory corruption, occurred.
• Inserting or removing memory cards will generally do nothing to cause the
CR1000 to miss data. These events affect table definitions because they can
affect table size allocations, but they will not create a situation where data
recovery is necessary.
Data can usually be recovered using the Datalogger Data Recovery wizard
available in DevConfig
(p. 111). Recovery is possible because data in memory is not
usually destroyed, only lost track of. So, the wizard recovers "data" from the
entire memory, whether or not that memory has been written to, or written to
recently.
Once you have run through the recovery procedure, consider the following:
If a CRD: drive (memory card) or a USB: drive (Campbell Scientific mass storage
device) has been removed since the data was originally stored, then the
Datalogger Data Recovery is run, the memory pointer will likely be in the wrong
location, so the recovered data will be corrupted. If this is the case, put the CRD:
