5.3 GPS and timing systems
5.3.1 XGPS
Syntax: on/off XGPS
Switches on or off the GPS system. To save power consumption under
normal operation, the CD24E1 only powers on the GPS occasionally to
update timing information. You can override this with the XGPS
command, where on/off is 0 to switch off the relay, and 1 to switch
it on. Once switched on, the system will check the GPS, update the fix,
and switch off for the period set by the HR-CYCLE command (see
below).
5.3.2 HR-CYCLE
Syntax: interval HR-CYCLE
Sets the interval between GPS fixes. The system will power on the GPS
system every interval hours and synchronize its internal clock with
GPS timing signals. Once the internal clock is sufficiently close to GPS
time, the GPS system will be automatically powered down for another
interval hours.
Setting interval to 0 will make the CD24E1 leave the GPS on
continuously. This is recommended if your installation has access to
mains power.
5.3.3 SET-RTC
Syntax: year month day hour minute second centisecond
