*   The ``UclaMiniscopeV4`` node connects to the ``Trigger`` node. The ``Trigger`` node represents a ``Condition`` operator named *Trigger*. A ``Condition`` operator emits the item it receives under specific conditions. To inspect the its conditional statement, double left-click the ``Trigger`` node. The ``Trigger`` node connects to the ``Image`` node. ``Trigger`` only emits items if its conditional statement (described in the next section) is ``TRUE``.

*   ``Trigger`` emits ``UCLAMiniscopeV4Frame`` if the ``Trigger`` member of ``UCLAMiniscopeV4Frame`` is ``True``.
