Describes how you can synchronously fire trigger using a synchronization clock.
Setting and Dividing a Synchronization Clock
After you have set a synchronization clock for the front and/or rear zones of your chassis, you can use the synchronization clock to control when triggers fire.
You can set a trigger to fire on an update edge of the full-speed or a divided synchronization clock. You can also fire a trigger asynchronously using this terminal, though a trigger synchronized to a time reference is generally more accurate than an asynchronous trigger. Using a synchronization clock to coordinate trigger firing is ideal for situations where you are trying to synchronize different signals coming through the front and rear zones of the chassis.
Place Connect Trigger Terminals on the diagram.
Wire instrument handle with the session handle from the niSync Properties function you used in Setting and Dividing a Synchronization Clock.
Set Divided Clock 1 as the value for synchronization clock. This divides the frequency of the synchronization clock by the value you set in the Clock Divisor 1 property and uses the result as the synchronization clock frequency for this trigger.
You can also set the synchronization clock terminal to the following values:
Divided Clock 2—Fires the trigger on an update edge of the second divided clock you created with the Clock Divisor 2 property.
Full Speed Clock—Fires the trigger on an update edge of the full-speed synchronization clock.
Asynchronous—Fires the trigger independently of the synchronization clock.
Select the source terminal and destination terminal for this trigger. The trigger is now set to fire on an update edge of the full-speed or divided synchronization clock.
