Starting with PXI Platform Services 17.5, you can use the SMB connector for trigger routing for Windows OS PXI(e) controllers. For Phar lap ETS and Linux Real-Time PXI(e) controllers, this feature is available starting with PXI Platform Services 19.0. You can reference the SMB connector with the terminal name /<hostname>/TRIG_SMB, where <hostname> is the controller's name on the network. There are three ways you can use TRIG_SMB:
Routes can be performed using most NI routing APIs that accept string-based terminal names, such as NI-DAQmx and NI-DCPower. Provide /<hostname>/TRIG_SMB as an input terminal to trigger the card, as shown in the code snippet below.

Use the DAQmx Signal Routing VIs to connect /<hostname>/TRIG_SMB to a PXI Trigger Line /<hostname>/PXI_Trig<number> on the chassis backplane. Then, point the card's trigger to the chosen PXI Trigger Line. This sends the signal from the SMB to a specified TTL or PFI line, allowing multiple PXI(e) cards to be triggered from the same source.
