Using Pxi With Compactpci - National Instruments 653X User Manual

Using PXI with CompactPCI

© National Instruments Corporation
You can use your PXI-653X device as a plug-in device in a standard
CompactPCI chassis, but you will not be able to access PXI-specific
functions, such as RTSI bus features detailed in the PXI Specification,
rev. 1.0.
The CompactPCI specification permits vendors to develop sub-buses that
coexist with the basic PCI interface on the CompactPCI bus. Compatible
operation is not guaranteed between CompactPCI devices with different
sub-buses nor between CompactPCI devices with sub-buses and PXI.
The standard implementation for CompactPCI does not include these
sub-buses. Your PXI-653X device will work in any standard CompactPCI
chassis adhering to the PICMG CompactPCI 2.0 R2.1 document.
PXI-specific features are implemented on the J2 connector of the
CompactPCI bus. The following table lists the J2 pins used by your
PXI-653X device. Your PXI device is compatible with any CompactPCI
chassis with a sub-bus that does not drive these lines. Even if the sub-bus is
capable of driving these lines, the PXI device is still compatible as long as
those pins on the sub-bus are disabled by default and not ever enabled.
