PXI Features
PXI Trigger Connectivity
The SMB connector on the NI 8171 series 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 for more information.
Upgrading RAM
You can change the amount of installed RAM on the NI 8171 series by
upgrading the SO-DIMM.
To upgrade the RAM, remove the NI 8171 series from the PXI chassis.
Remove the old SO-DIMM module and install the new SO-DIMM in the
socket as shown in Figure 2-3.
National Instruments offers the following types of SO-DIMMs for use with
the NI 8171 series controller.
• 128 MB, 16MB

• 256 MB, 32MB
× 64, 7.5ns, 1.05 in. max
Note National Instruments has tested and verified that the SO-DIMMs we sell work with
the NI 8171 series. We recommend you purchase your SO-DIMM modules from National
Instruments. Other off-the-shelf SO-DIMM modules are not guaranteed to work properly.
