Table 111. CR800 Terminal Commands
Option Description
Use
REBOOT
Program recompile
Typing “REBOOT” rapidly will recompile the CR800
program immediately after the last letter, "T", is entered.
Table memory is retained. NOTE When typing
REBOOT, characters are not echoed (printed on
terminal screen).
SDI12
SDI12 talk through
Issue commands from keyboard that are passed through
the CR800 SDI-12 port to the connected device. Similar
in concept to Serial Talk Through.
T
Unused
U
Data recovery
Provides the means by which data lost when a new
program is loaded may be recovered.
Problem: User downloads a new program, then realizes
that valuable data written prior to the download has not
been collected.
Solution: By running the following procedure
immediately, some or all of the lost data may be
recovered.
1. Download the old program back into memory.
2. Go into terminal mode and select option U.
3. When asked “OK? Reenter? Skip?”, select Y (=OK).
This procedure will put the "filled" flag in the CR800 for
that data table and so allow datalogger support software
to collect the whole table. If the table was
not full, data pulled from unfilled section will be garbage.
