Intf.SrcTerm.StartTrigger

Last Modified: February 7, 2020

Specifies the name of the internal terminal to use as the interface Start Trigger. The data type is NI Terminal (DAQmx terminal).

Use this property to connect the interface Start Trigger to triggers in other modules and/or interfaces. When you read this property, you specify the interface Start Trigger as the source of a connection. When you write this property, you specify the interface Start Trigger as the destination of a connection, and the value you write represents the source.

Data type: datatype_icon

Long Name: Interface:Source Terminal:Start Trigger

Class: XNET Session

Permissions: Read/Write

For examples that demonstrate use of this property to synchronize NI-XNET and NI-DAQmx hardware, refer to the Synchronization category within the NI-XNET examples.

The connection this property creates is disconnected when you clear (close) all sessions that use the interface.

This property is supported for C Series modules in a CompactDAQ chassis. It is not supported for CompactRIO, PXI, or PCI (refer to the XNET Connect Terminals VI for those platforms).

The digital trigger signal at this terminal is for the Start Interface transition, to begin communication for all sessions that use the interface. This property routes the start trigger, but not the timebase (used for timestamp of received frames and cyclic transmit of frames). Timebase routing is not required for CompactDAQ, because all modules in the chassis automatically use a shared timebase.

Where This Property Is Available:

Desktop OS: Windows

FPGA: Not supported

Web Server: Not supported in VIs that run in a web application
