How to connect trigger terminals and synchronize triggers using NI-Sync.
You can use
Connect Trigger Terminals
to link hardware trigger lines together. You can also use
Connect Software Trigger
to connect the global software trigger to a destination trigger terminal.
-
Place
Initialize
on the diagram.
-
Place
Connect Trigger Terminals
or
Connect Software Trigger
on the block diagram.
-
Wire a constant or control to
source terminal
and
destination terminal
and select the source of the trigger and the destination to connect it to.
-
(Optional) Set additional parameters for the new trigger route:
-
Select a value for
synchronization clock. Use this value to send the trigger signal from the source terminal to the destination terminal asynchronously or on an update edge of the specified clock.
-
Select a value for
update edge. Use this value to determine whether to align the trigger signal with the rising or falling edge of the synchronization clock.
-
Select a value for
invert. Use this value to determine whether to invert the source terminal signal when it reaches the destination terminal. You can use this terminal for differential analysis or to eliminate noise in your signal.
-
If you are using
Connect Software Trigger, select a value for
delay. Use this value to delay firing the global software trigger by the selected value when you invoke
Send Software Trigger.
-
(Optional) If you are using
Connect Software Triggers, place
Send Software Trigger
in the place on the diagram where you would like to fire the software trigger.
-
Place
Disconnect Trigger Terminals
or
Disconnect Software Trigger
on the block diagram and wire the appropriate terminals.
-
Place
Close
on the diagram to close the NI-Sync I/O session.
