Routes triggers through the PXI backplane, between devices, or between multiple chassis.
Once a terminal route is connected, you can invert the trigger signal at the destination terminal, synchronize the trigger to the rising or falling edge of a synchronization clock, fire the trigger asynchronously, or route the trigger to other trigger terminals.
You can also route clocks along some trigger lines by setting a full speed or divided synchronization clock as the source terminal.
Refer to Trigger Terminal Connections for a list of compatible trigger sources and destinations for this VI.

Note The destination terminal determines the source of the trigger's synchronization clock. PFI and PFI_LVDS lines are in the front trigger zone, and PXI_Trig, PXI_Star, and PXIe_DStar lines are in the rear trigger zone. You can select the source of the full speed synchronization clock for a given trigger zone and adjust the speed of the divided clocks by using the niSync Property Node. |
![]() |
update edge (Rising Edge) specifies on which update edge of the synchronization clock to propagate the trigger.
Valid values:
|
||||||||||||
![]() |
synchronization clock specifies whether to use the full-speed or a divided synchronization clock to control when the trigger fires. The trigger will be synchronized with the rising or falling edge of the clock you select in this terminal. Valid values:
|
||||||||||||
![]() |
instrument handle specifies the instrument handle that you obtain from niSync Initialize. |
||||||||||||
![]() |
source terminal specifies the source of the trigger you want to connect to the destination terminal. Valid values:
|
||||||||||||
![]() |
destination terminal specifies the destination trigger terminal that the source terminal will connect to. Valid values:
|
||||||||||||
![]() |
error in (no error) describes error conditions that occur before this node runs. This input provides standard error in functionality. |
||||||||||||
![]() |
invert specifies whether or not to invert the source terminal signal at the destination terminal.
Valid values:
|
||||||||||||
![]() |
instrument handle out returns the instrument handle that you obtain from niSync Initialize. |
||||||||||||
![]() |
error out returns error conditions that occur after this node runs. This output provides standard error out functionality. |
