These devices can interface to an SCXI systemthe instrumentation front
end for plug-in DAQ devicesso that you can acquire analog signals from
thermocouples, RTDs, strain gauges, voltage sources, and current sources.
You can also acquire or generate digital signals for communication and
control.
Using PXI with CompactPCI
Using PXI compatible products with standard CompactPCI products is an
important feature provided by PXI Specification, Revision 1.0. If you use a
PXI compatible plug-in card in a standard CompactPCI chassis, you cannot
use PXI-specific functions, but you can still use the basic plug-in card
functions. For example, the RTSI bus on your PXI E Series device is
available in a PXI chassis, but not in a CompactPCI chassis.
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 E Series device works in any standard CompactPCI
chassis adhering to PICMG CompactPCI 2.0 R2.1 core specification.
PXI specific features are implemented on the J2 connector of the
CompactPCI bus. Table 3-3, Pins Used by PXI E Series Device, lists the J2
pins used by your PXI E Series device. Your PXI device is compatible with
any Compact PCI 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. Damage can result if these lines are driven by the sub-bus.
