Thesefiles and directories are copied exactly from the manufacturer distributiondisks, so the naming conventions vary from peripheral to peripheral.Because the naming conventions may not be completely straightforward,National Instruments provides a text file named drivers.txt in thec:\images\pxi-8180 directory. The drivers.txt file explains howto install support for each peripheral. You may want to print this file forreference when you install your peripheral device drivers.PXI FeaturesPXI Trigger ConnectivityThe SMB connector on the NI PXI-8184/8185 front panel can connectto or from any PXI backplane trigger line through software. A triggerallocation process is needed to prevent two resources from connectingto the same trigger line, resulting in the trigger being double-driven andpossibly damaging the hardware. At the time of this manual’s publication,this software is not yet available; however, an interim trigger routingsoftware utility is available from National Instruments.
