• Restores settings to default.
• Initializes system variables.
• Clears communications memory.
Operating systems can also be sent using the program Send feature in datalogger
support software
(p. 76). Beginning with CR800 operating system v.16, settings
and status are preserved when sending a subsequent operating system by this
method; data tables are erased. Rely on this feature with caution, however, when
sending an OS to CR800s in remote and difficult-to-access locations.
8.3.3.2 Program Send Reset
Final Storage (p. 432) data are erased when user programs are uploaded, unless
preserve / erase data options are used. Preserve / erase data options are presented
when sending programs using File Control Send
(p. 431) command and CRBasic
Editor Compile, Save and Send
(p. 428). See Preserving Data at Program Send (p.
110)
for a more-detailed discussion of preserve / erase data at program send.
8.3.3.3 Manual Data-Table Reset
Data-table memory is selectively reset from
• Support software Station Status
(p. 444) command
• external keyboard / display: Data | Reset Data Tables
8.3.3.4 Formatting Drives
CPU:, USR:, and USB: drives can be formatted individually. Formatting a drive
erases all files on that drive. If the currently running user program is found on the
drive to be formatted, the program will cease running and any SRAM data
associated with the program are erased. Drive formatting is performed through
datalogger support software
(p. 547) Format (p. 431) command.
8.3.4 File Management
As summarized in table File Control Functions (p. 324), files in CR800 memory
(program, data, CAL, image) can be managed or controlled with datalogger
support software
(p. 76), CR800 web API, or CoraScript. Use of CoraScript is
described in the LoggerNet software manual, which is available at
www.campbellsci.com. More information on file attributes that enhance
datalogger security, see the Security
(p. 70) section.
