Routing and enabling a trigger
The provided trigger signals are not dedicated to a particular connector. Trigger signals
can be mapped to one or more User x or T/M connectors.
Use the
Local and global connectors settings to configure the signal mapping, the
polarity, the trigger threshold and the input impedance of the input connectors.
To route and enable a trigger signal, perform the following
general steps :
●
Define the signal source and the effect of a trigger event.
Select the "Trigger In > Mode" and "Trigger In > Source".
●
Define the connector where the selected signal is provided.
Use the "Global Connectors" settings.
