Trigger
The TRG connector is the software-controlled trigger connection for
routing PXI triggers to or from the backplane trigger bus.
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 software is not yet available for Windows.
Contact National Instruments for more information.
