The following list details the hardware models supported in NI-PXImc:
The PXIe-8383mc PXImc adapter modules and the PXIe-8830mc PXImc processor modules utilize a x8 PCI Express 2.0 interface for transferring data. National Instruments recommends using the NI PXImc modules with a PXI-Express chassis and controller combination that provide high PCI Express bandwidth. If you are using the PXIe-8383mc or PXIe-8830mc module in a chassis with an NI embedded controller, then you must update the BIOS software on that embedded controller to the latest released BIOS software prior to connecting the hardware. For more information, refer to KnowledgeBase 2GIGKD0Z, Determining and Upgrading PXI and VXI Embedded Controller BIOS Versions.
Bandwidth experienced when using NI-PXImc may be affected by bandwidth capabilities of the controller or the chassis. If you experience lower than expected bandwidth when using NI-PXImc, check that your controller and chassis are capable of supporting the desired bandwidth, and that your PXImc adapter module is inserted into an appropriate chassis slot to obtain the best performance. Consult your chassis and controller documentation for specific information relevant to your hardware configuration.
Note National Instruments recommends an NI high performance PXIe embedded controller be used both as the system controller and as the controller connected to the front panel of the PXImc module. Refer to NI-PXImc General Considerations for more information.
For proper operation with NI-PXImc, all NI Embedded Controllers must be running the latest BIOS. For more information, refer to KnowledgeBase 2GIGKD0Z, Determining and Upgrading PXI and VXI Embedded Controller BIOS Versions.
National Instruments recommends an NI high performance PXIe embedded controller be used both as the system controller and as the controller connected to the front panel of the PXImc module. If you are connecting the PXImc module to an NI PXIe embedded controller, you must update the BIOS software on that embedded controller to the latest released BIOS software prior to connecting the hardware. Refer to NI Embedded Controller BIOS Versions for information about updating the BIOS.
Bandwidth experienced when using NI-PXImc may be affected by bandwidth limitations in the controller or on the chassis backplane. If you experience lower than expected bandwidth when using NI-PXImc, check that your controller and chassis are capable of supporting the desired bandwidth, and that your PXImc card is inserted into an appropriate chassis slot to obtain the best performance. Consult your chassis and controller documentation for specific information relevant to your hardware configuration.
National Instruments recommends setting the hardware Mode DIP switch (Switch 4) to User Mode for optimal performance. Refer to the NI PXImc Devices Getting Started Guide, available in the PXIe-8383mc kit and on ni.com/manuals, for information about the DIP switch functionality and location. Refer to the Hardware Configuration section in the NI-PXImc Help for more information about the differences between the two modes.
The PXIe chassis that contains the PXIe-8383mc module must be powered on before the system connected to the front panel connector is powered on. Furthermore, the PXIe chassis that contains the PXIe-8383mc module must be continuously powered while the system connected to the front panel connector is powered on. If it is necessary to turn off the chassis containing the PXIe-8383mc, the system connected to the front panel must be powered off first. Refer to the NI PXImc Devices Getting Started Guide, available in the PXIe-8383mc kit and on ni.com/manuals, for more information about power sequence.
Many third-party PXI Express controllers, both PXIe embedded controllers and desktop PCs, have been observed to have BIOS issues that prevent the enumeration of some PXIe modules. If you have boot or device enumeration issues, set the hardware Mode DIP switch (Switch 4) on your PXImc modules to Factory mode and try again. Refer to the NI PXImc Devices Getting Started Guide, available in the PXIe-8383mc kit and on ni.com/manuals, for information about the DIP switch functionality and location. If you continue to have issues, either contact your controller vendor for a BIOS fix or upgrade your controller to a National Instruments high performance PXIe embedded controller.
When configuring the PXIe-8383mc module in "User" mode, NI recommends no more than six modules be connected to a single system running 64-bit Windows 10, Windows 8.1 or Windows 7, and no more than four modules be connected to a system running 32-bit Windows 8.1 or Windows 7, either directly in the system or connected through the PXImc module front panel connector. If you are using the PXIe-8383mc or PXIe-8830mc in a system with LabVIEW Real-Time (ETS) OS, NI recommends no more than four modules to a single system, either directly in the system or connected through the front panel connector. If your system needs more than the recommended number of modules, either change Switch 4 to the "FACT" position for all modules or contact National Instruments support.
NI recommends no more than six PXIe-8830mc modules be placed in a single system with the embedded controller running Windows 10/8.1/7(64-bit), and no more than four modules be placed in a system running Windows 10/8.1/7 (32-bit) on the host/embedded controller. If you are using the PXIe-8830mc in a system with the embedded controller running LabVIEW Real-Time (ETS) OS, NI recommends no more than four NI PXI-8830mc modules be in the system. If your system needs more than the recommended number of modules contact National Instruments support.
