PXI TriggerConnectivity

The SMB connectoron the NI8 171 seriesfront panel can connect to or
fromany PXI backplane trigger line through softw are. A trigger allocation
processis 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
software is not yet available; however, an interim trigger routing software
utility is available from National Instruments. Contact National
Instruments for more information.
