Do not apply more than 10V to the GPI port, as this could cause permanent
damage.
12.14 Timespan
The Timespan section allows for four periods of time to be defined. The
beginning and end of the time periods will trigger actions in the show control
page.
An advantage of Timespans over normal scheduler actions is that Timespans
are power-cycle safe. When the CueCore2 is without power during the moment
of a normal scheduler trigger then it will miss that trigger. Timespans, however,
will still receive the trigger once the power is restored after the moment has
occurred.
Timespans are ideal for defining periods of time during a year (like Christmas
or Easter) or periods during the day (like opening times).
When entering the date and time data, XX's can be used to signify a 'don't
care'. This allows for easily programming of yearly, monthly or daily re-occuring
events.
