• Timer Start Time: Specify starting time for the timer. The
starting time is the actual calendar date and real-time clock.
Once a timer reaches this specified Start Time, the power
outlet on/off state will flip. It is in the format of
“month:day:hour:minute:second”. For example, to start
changing the power outlet on/off state at 6:31:2pm, on June
20th, the entry data is 6:20:18:31:02.
• Timer Period: Specify the timer period. It is in the format of
“days:hours:minutes:seconds”, which is not a calendar and
real-time clock entry type. The period setting is used for
applications that require the power outlet to continuously
change on/off in a specific interval. For example, you need to
schedule power reboot for the outlet daily, the period is 24
hours. Your entry will be 00:24:00:00.
• Timer Loop Count: The number of Periods for the Timer is
defined as Loop Count. For example, you schedule the timer
to flip the power outlet states in every 20 seconds and want
to repeat 300 times, your entry will be 300.
Enter “0” for this setting, if you schedule the power outlet
simply change power state from on to off, or from off to on a
specific time and date.
Enter “1” for the setting, if you schedule the power outlet
to be on-off-on, or off-on-off once. For example, the system
executes one power reboot cycle on a specific date and
time.
• Toggle Duration: Specify the duration of the power outlet
state that toggles when a new Timer Period starts. This
parameter is meaningful if the Timer Loop Count is > 0. The
unit for the duration is in seconds. The concept of the
specification can also be viewed as Duty Cycle. The value of
this parameter should be 0 < Toggle Duration < Timer Period.
