Use this VI to route signals (clocks, triggers, and events) to the output terminal you specify. Refer to your device documentation for valid signal destinations.

Any routes created within a session persist after the session closes to prevent signal glitching. To unconfigure signal routes created in previous sessions, set the reset instrument parameter in the niHSDIO Init Generation Session VI or the niHSDIO Init Acquisition Session VI to TRUE or use the niHSDIO Reset Device VI.

If you export a signal with this VI and commit the session, the signal is routed to the output terminal you specify. If you then reconfigure the signal to have a different output terminal, the previous output terminal is tristated after the session is committed. If you change output terminal to Do Not Export when you commit the session, the previous output terminal is tristated.

instrument handle identifies your instrument session. instrument handle is obtained from the niHSDIO Init Acquisition Session VI, the niHSDIO Init Generation Session VI, or the niHSDIO Init Ext Cal VI.

signal identifier describes the signal being exported.

You can select Script Trigger 0, Script Trigger 1, Script Trigger 2, Script Trigger 3, Marker 0, Marker 1, Marker 2, Marker 3, or None.

Note When using the NI 6544/6545/6547/6548, Script Trigger 3 and Marker 3 are unavailable.

signal specifies the signal to export.

Sample Clock	Device Sample clock.
Reference Clock	Device Reference clock.
Start Trigger	Device Start trigger.
Reference Trigger	Device Reference trigger (dynamic acquisition only).
Advance Trigger	Device Advance trigger (dynamic acquisition only)
Pause Trigger	Device Pause trigger (dynamic generation only).
Script Trigger	Device Script trigger (dynamic generation only—requires signal identifier to describe a particular Script trigger).
Stop Trigger	Device Stop trigger (dynamic generation only).
Data Active Event	Data Active event (dynamic generation only).
Ready for Start Event	Ready for Start event.
Ready for Advance Event	Ready for Advance event (dynamic acquisition only).
Marker Event	Marker event (dynamic generation only—requires signal identifier to describe a particular marker).
End of Record Event	End of Record event (dynamic acquisition only).
Onboard Ref Clock	Device onboard Reference clock (PCI devices only).

Selecting Script Trigger or Marker Event requires a signal identifier to describe the particular signal.

output terminal specifies the terminal where the signal is exported.

Do not export signal	The signal is not exported.
PFI 0	The signal is exported to the PFI 0 front panel connector.
PFI <1..3>	The signal is exported to PFI <1..3> on the DDC front panel connector.
PXI Trigger Line/RTSI <0..7>	The signal is exported to PXI trigger line or RTSI trigger line.
CLK OUT	The signal is exported to the front panel CLK OUT connector.
DDC CLK OUT	The signal is exported to the DDC CLK OUT pin on the DDC front panel connector.

error in (no error) describes error conditions that occur before this node runs. This input provides standard error in functionality.

	status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE.
	code is the error or warning code. The default is 0. If status is TRUE, code is a negative error code. If status is FALSE, code is 0 or a warning code.
	source identifies where an error occurred. The source string includes the name of the VI that produced the error, what inputs are in error, and how to eliminate the error.

instrument handle out passes a reference to your instrument session to the next VI. instrument handle is obtained from the niHSDIO Init Acquisition Session VI or the niHSDIO Init Generation Session VI.

error out contains error information. This output provides standard error out functionality.

	status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.
	code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.
	source identifies where and why an error occurred. The source string includes the name of the VI that produced the error, what inputs are in error, and how to eliminate the error.
