PXI Features
PXI Trigger Connectivity
The SMB connector on the NI PXI-8186/8187 front panel can connect to
or from any PXI backplane trigger line through software. 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; however, an interim trigger routing
software utility is available from National Instruments. Contact National
Instruments or refer to KnowledgeBase 2RCBPFWD at
ni.com/support
for more information.
Upgrading RAM
You can change the amount of installed RAM on the NI PXI-8186/8187 by

To upgrade the RAM, remove the NI PXI-8186/8187 from the PXI chassis.
Remove the old SO-DIMM module and install the new SO-DIMM in
the socket as shown in Figure 2-5.
