DAQmx Export Signal Properties
Use the DAQmx Export Signal properties to route a control signal within a device or from one device to another. These routes are task-based and are useful for sharing clocks and triggers among multiple devices.

| Events:Change Detection Event:Output Terminal | Specifies the terminal to which to route the Change Detection Event. Details |
| Events:Change Detection Event:Pulse:Polarity | Specifies the polarity of an exported Change Detection Event pulse. Details |
| Events:Counter Output Event:Output Terminal | Specifies the terminal to which to route the Counter Output Event. Details |
| Events:Counter Output Event:Output Behavior | Specifies whether the exported Counter Output Event pulses or changes from one state to the other when the counter reaches terminal count. Details |
| Events:Counter Output Event:Pulse:Polarity | Specifies the polarity of the pulses at the output terminal of the counter when CtrOutEvent.OutputBehavior is Pulse. NI-DAQmx ignores this property if CtrOutEvent.OutputBehavior is Toggle. Details |
| Events:Counter Output Event:Toggle:Idle State | Specifies the initial state of the output terminal of the counter when CtrOutEvent.OutputBehavior is Toggle. The terminal enters this state when NI-DAQmx commits the task. Details |
| Events:Handshake Event:Output Terminal | Specifies the terminal to which to route the Handshake Event. Details |
| Events:Handshake Event:Output Behavior | Specifies the output behavior of the Handshake Event. Details |
| Events:Handshake Event:Delay Value | Specifies the number of seconds to delay after the Handshake Trigger deasserts before asserting the Handshake Event. Details |
| Events:Handshake Event:Interlocked:Asserted Level | Specifies the asserted level of the exported Handshake Event if HshkEvent.OutputBehavior is Interlocked. Details |
| Events:Handshake Event:Interlocked:Assert on Start | Specifies to assert the Handshake Event when the task starts if HshkEvent.OutputBehavior is Interlocked. Details |
| Events:Handshake Event:Interlocked:Deassert Delay Value | Specifies in seconds the amount of time to wait after the Handshake Trigger asserts before deasserting the Handshake Event if HshkEvent.OutputBehavior is Interlocked. Details |
| Events:Handshake Event:Pulse:Polarity | Specifies the polarity of the exported Handshake Event if HshkEvent.OutputBehavior is Pulse. Details |
| Events:Handshake Event:Pulse:Width Value | Specifies in seconds the pulse width of the exported Handshake Event if HshkEvent.OutputBehavior is Pulse. Details |
