Backplane Overview
3.1 CompactPCI Compatibility
The PXIS-2700 backplane cBX-3018L is compatible with PXI-compatible
products and standard CompactPCI products.
The signals on the P1 connector of the backplane meet the requirements
of the CompactPCI specification for both the peripheral and system
modules.
The PXI-specific signals are located on P2. Only the signals that are
reserved or not used in the CompactPCI 64-bit specification are found on
PXI-specific signals. Therefore, all modules that meet the requirements of
the CompactPCI 64-bit specification will function in the PXIS-2700.
3.2 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, which are used 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 up peripheral slots.
3.3 Star Trigger Slot
The Star Trigger (ST) slot is Slot 2. This slot has a dedicated trigger line
between itself and slots 3-15 is intended for modules with ST functionality
that can provide individual triggers to the peripherals.
