PXI Express Trigger Connectivity
The SMB connector on the NI PXIe-8840 Quad-Core front panel can connect to or
from any PXI Express backplane trigger line. A trigger allocation process is needed to
prevent two resources from connecting to the same trigger line, resulting in the
trigger being double-driven and possibly damaging the hardware. At the time of this
manual’s publication, this soware is not yet available for Windows. Contact
National Instruments for more information.
