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 “year:month:day:ho
ur:minute:second”. For example, to start changing the power outlet on/off state at 7:17:27pm, on July 20th 2008,
the entry data is 08:07:20:19:17:27.
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.
Toggle Duration:
Specify the duration of the power outlet and state the 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.
