Guralp Systems CMG-DM24 - Manual (Page 55)

Operator's guide
HR-CYCLE
Syntax: interval HR-CYCLE
Sets the time to wait between GPS synchronizations.
To save power, the DM24 can switch off the attached GPS receiver
once its internal precision clock has been successfully synchronized.
The GPS receiver is reactivated every interval hours to ensure that
the clock remains correct, and shut down again once the clock error
has stabilized.
Setting interval to zero disables this function, i.e. the GPS will be
powered all the time. This is the best setting to use in installations
with access to mains (outlet) power. The maximum allowed value for
interval is 23.
SET-CLOCK
Syntax: SET-CLOCK (interactive)
Sets the internal clock.
SET-CLOCK
Enter Date & Time -
YYYY MM DD HH MM SS
2006 02 01 12 53 25 Clock set to 2006 2 1 12:53:27 ok_SBHY
The time should be entered in the form year month day hour
minute second, padding each field with zeroes so that they line up
with the guide above.
If the DM24 does not recognize the time format you have used, it will
output the message:
Invalid Time Entry.
This setting will be overridden when the GPS system next
synchronizes the clock.
TIME?
Syntax: TIME?
Displays the current date and time.
