Section 10. Troubleshooting Table 118. CR3000 Terminal Commands Option Description REBOOT Program recompile SDI12 SDI12 talk through T Unused U Data recovery V Low level memory dump W Communications sniffer X Peripheral bus module identify Use Typing "REBOOT" rapidly will recompile the CR3000 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). Issue commands from keyboard that are passed through the CR3000 SDI-12 port to the connected device. Similar in concept to Serial Talk Through. 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 CR3000 for that data table and so allow datalogger support software (p. 404, p. 453) to collect the whole table. If the table was not full, data pulled from unfilled section will be garbage. Campbell Scientific engineering tool Enables monitoring of CR3000 communications traffic.
