The NI 6034E/6035E/6036E device can interface to an SCXI system—
the instrumentation front end for plug-in DAQ devices—so 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 2.0. If you
use a PXI-compatible plug-in card in a standard CompactPCI chassis, you
are unable to 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 1-1 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.
Caution
Damage can result if these lines are driven by the sub-bus.
