Connecting and Synchronizing Triggers
You can use niSync Connect Trigger Terminals to link hardware trigger lines together. You can also use niSync Connect Software Trigger to connect the global software trigger to a destination trigger terminal. Complete the following steps to connect trigger terminals:
- Place niSync Initialize.
- Place niSync Connect Trigger Terminals or niSync Connect Software Trigger.
- Wire a constant or control to source and destination and select the source of the trigger and the destination to connect it to.
 |
Note The only acceptable source value for niSync Connect Software Triggers is Global Software Trigger. |
- (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. Refer to Firing Triggers with a Synchronization Clock for more detailed information about synchronizing triggers.
- 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 niSync Connect Software Triggers, select a value for delay. Use this value to delay firing the global software trigger by the selected value when you invoke niSync Send Software Trigger.
- (Optional) If you are using niSync Connect Software Triggers, place niSync Send Software Trigger on the block diagram where you would like to fire the software trigger.
- Place niSync Disconnect Trigger Terminals or niSync Disconnect Software Trigger on the block diagram and wire the appropriate terminals.
- Place niSync Close on the block diagram to close the NI-Sync I/O session.
