Guralp Systems CMG-DM24 - Manual (Page 91)

Operator's guide
After a short time, the message will change to
2005 8 10 12:36:00 GPS Control settling Auto 3-D [-5 Not sync'd]
Eventually, the GPS control system will be able to synchronize the
internal clock, and the message will change to
2005 8 10 12:38:01 GPS Control settling Auto 3-D [-4]
2005 8 10 12:41:01 326 MicroSeconds Slow Freq error -7 e-9 Auto
3-D [-4]
The system is now reporting the current offset of the internal clock
from GPS time (whether slow or fast), and the current frequency error.
It will now continuously adjust the internal clock for as long as the
GPS is powered up.
If you have chosen to save energy by enabling GPS power cycling, the
DM24 will switch off the GPS once a satisfactory fix is obtained, and
begin free-running on the internal clock. Whilst this is happening, the
line will report
2005 8 10 17:06:27 GPS switched Off
Boot status
PLPGG SBHY00 CMG-3T
Boot Log : 143 Power cycles 294 Watchdog resets
Last boot 2006 1 12 16:18:57 2006 1 17 17:15:14
These three lines repeat information from the last re-boot:
•
in the first, the System ID, the Stream ID of the status stream,
and the current Sensor Type;
•
in the second, the number of times the digitizer has been power
cycled, and the number of times it has been reset without power
cycling (e.g. by a re-boot after reconfiguring the module: a
“soft” reset); and
•
in the thrid, the date and time of the last power cycle and of the
last soft reset.
