DC Power Cable (PXI-1031DC Only)
An optional DC power cable is available from National Instruments to
provide power through the DC input connector on the rear panel of the
chassis.
PXI-1031/PXI-1031DC Backplane Overview
Interoperability with CompactPCI
The PXI-1031/PXI-1031DC backplane is interoperable with 5 V and
universal PXI-compatible products and standard CompactPCI products.
This is an important feature, because some PXI systems may require
components that do not implement PXI-specific features. For example,
you may want to use a standard CompactPCI network interface card in a
PXI chassis.
The signals on the backplane P1 connectors meet the requirements of the
CompactPCI specification for both peripheral and system modules. Refer
to Appendix B,
, for pinout information.
The PXI-specific signals are on the backplane P2 connectors and are
found only on those signal lines reserved or not used in the CompactPCI
64-bit specification. Therefore, all modules that meet the requirements
of the CompactPCI 64-bit specification will function in the
PXI-1031/PXI-1031DC. Refer to Appendix B,
, for pinout
information.
The chassis backplane has +5 V V(I/O). Refer to the
CompactPCI
Specification PICMG 2.0 R 3.0
for details regarding V(I/O).
System Controller Slot
The system controller slot is slot 1 of the chassis as defined by the PXI
specification. It has three controller expansion slots for system controller
modules that are wider than one slot. As defined in the PXI specification,
these slots allow the controller to expand to the left to prevent the controller
from using peripheral slots.
