National Instruments PXI NI PXI-8105 Upgrading RAM

Chapter 2 Installation and Configuration

1. Launch MAX.

2. In the Configuration tree, click the Devices and Interfaces branch to

expand it.

3. If the PXI system controller has not yet been configured, it is labeled

PXI System (Unidentified). Right-click this entry to display the

pop-up menu, then select the appropriate controller model from the

Identify As submenu.

4. Click the PXI System controller. The chassis (or multiple chassis, in a

multichassis configuration) is listed below it. Identify each chassis by

right-clicking its entry, then selecting the appropriate chassis model

through the Identify As submenu. Further expanding the PXI System

branch shows all devices in the system that can be recognized by

NI-VISA. When your controller and all your chassis are identified,

the required pxisys.ini file is complete.

The PXI specification allows many combinations of PXI chassis and

system modules. To assist system integrators, the manufacturers of

PXI chassis and system modules must document the capabilities of their

products. The minimum documentation requirements 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 the 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 system initialization file called pxisys.ini (PXI System

Initialization). The NI PXI-8105 uses MAX to generate the pxisys.ini

file from the chassis.ini fil e.

Device drivers and other utility software read the 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 PXI-8105 by

upgrading the SO-DIMM.

To upgrade the RAM, remove the NIPXI-8105 from the PXI 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
