Chapter 2 Installation and Configuration© National Instruments Corporation 2-15 NI PXI-8105 User ManualBasic PXI System Configuration1. Launch MAX.2. In the Configuration tree, click the Devices and Interfaces branch toexpand it.3. If the PXI system controller has not yet been configured, it is labeledPXI System (Unidentified). Right-click this entry to display thepop-up menu, then select the appropriate controller model from theIdentify As submenu.4. Click the PXI System controller. The chassis (or multiple chassis, in amultichassis configuration) is listed below it. Identify each chassis byright-clicking its entry, then selecting the appropriate chassis modelthrough the Identify As submenu. Further expanding the PXI Systembranch shows all devices in the system that can be recognized byNI-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 andsystem modules. To assist system integrators, the manufacturers ofPXI chassis and system modules must document the capabilities of theirproducts. The minimum documentation requirements are contained in.ini files, which consist of ASCII text. System integrators, configurationutilities, and device drivers can use these .ini files.The capability documentation for the chassis is contained in achassis.ini file provided by the chassis manufacturer. The informationin this file is combined with information about the system controller tocreate a single system initialization file called pxisys.ini (PXI SystemInitialization). The NI PXI-8105 uses MAX to generate the pxisys.inifile from the chassis.ini file.Device drivers and other utility software read the pxisys.ini file toobtain system information. For detailed information about initializationfiles, refer to the PXI specification at www.pxisa.org.Upgrading RAMYou can change the amount of installed RAM on the NI PXI-8105 byupgrading the SO-DIMM.To upgrade the RAM, remove the NI PXI-8105 from the PXI chassis. Tooptimize both memory capacity and system performance, use the same sizeand speed memory module in each of the two module slots. The use of
