When programming the PXIe-5644R using NI-RFSA and NI-RFSG, National Instruments recommends that you reserve the trigger lines used by NI PXI Express devices. If two PXI Express devices try to drive the same trigger line in different applications or if the PXI Express devices are not programmed to work together, the application does not work. You can use Measurement & Automation Explorer (MAX) to reserve trigger lines.

Notice Notice  In some cases, third-party PXI Express devices can be damaged if two PXI Express devices try to drive the same trigger line in different applications or if the PXI Express devices are not programmed to work together.

Reserving Trigger Lines in MAX

You can configure the PXI Express triggers in MAX. MAX maintains the trigger reservation for the NI module even after you cycle power to the PXI Express chassis.
