Timers
Timers and Server-based Timers can be used to display time values in VisTool runtime. Each one can either
count-up from 00:00 or count-down from a starting value, and be started automatically (from say a mic source)
or manually (from start, stop and reset buttons). Use a standard Timer for stand-alone VisTool operation. Server-
based Timers enable the synchronization of timers across multiple VisTools.
16.10.1 Standard Timers
"System -> Definition -> Parameter = Timers"
This branch of the ON-AIR Designer 'Tree Definition' sets the options for the six standard timers included in
every configuration. Choose a standard timer if you do not need synchronized operation.

System

" in 'Tree Definition' and the
Logic

the timer parameters.
ON-AIR Designer Standard Timers
The fields can be used to name each timer and define how it is triggered:
Parameter
Timer – reference name for the element.
Time N Name
Enter a reference name for the timer.
Timer N Start
Assigns a control signal to start the timer. The timer will start from its current position.
If you want a key to always start the timer from 00:00:00:00, assign the same key to both the
Timer N Start
and
Timer N Reset
functions.
Timer NStop
Assigns a control signal to stop the timer.
Timer N Reset
Assigns a control input signal to reset the timer to 00:00:00:00.
Timer N Restart
Assigns a control input signal to restart the timer from its current position.
In the 'Tree Selection' window, the following outputs appear under “Logic -> Definition -> Parameter Timer”.
These can be used to illuminate the trigger keys and/or signal the timer alarm status:
Timer N Run
Active when the timer is running. Can be used to illuminate the MF Key controlling the timer.
Timer N Alarm
Active when the timer alarm is active.
