products. PXI Express devices must provide a driver and .ini file for
identification. These files are provided as part of the PXI Platform Services
software included with your controller. The minimum documentation
requirements for PXI-1 are contained in .ini files, which consist of ASCII
text. System integrators, configuration utilities, and device drivers can use
these .ini files.
The capability documentation for a PXI-1 chassis is contained in a
chassis.ini file provided by the chassis manufacturer. The information
in this file is combined with information about the system controller to
create a single PXI-1 system initialization file called pxisys.ini
(PXI System Initialization). The NI PXIe-8105 uses MAX to generate the
pxisys.ini file from the chassis.ini file.
Device drivers and other utility software read the pxiesys.ini and
pxisys.ini file to obtain system information. For detailed information
about initialization files, refer to the PXI specification at www.pxisa.org.
Upgrading RAM
You can change the amount of installed RAM on the NI PXIe-8105 by
upgrading the SO-DIMMs.
To upgrade the RAM, remove the NIPXIe-8105 from the PXI Ex press
chassis. To optimize both memory capacity and system performance, use
the same size and speed memory module in each of the two module slots.
The use of different size modules in each slot is supported, but system
performance will be slower than using two matched modules. However,
two mismatched modules will result in better performance than using a
single module.
National Instruments offers the following types of SO-DIMMs for use with
the NI PXIe-8105 controller.
• PC2-5300 512 MB, 64 MB × 64, CL 5, 1.18 in. max
(NI part number 779302-512)
• PC2-5300 1 GB, 128 MB × 64, CL 5, 1.18 in. max
(NI part number 779302-1024)
Note National Instruments has tested and verified that the DDR2 SO-DIMMs we sell
work with the NI PXIe-8105. We recommend you purchase your DDR2 SO-DIMM
modules from National Instruments. Other off-the-shelf DDR2 SO-DIMM modules
are not guaranteed to work properly.
