3 Backplane Overview
3.1 Interoperability with CompactPCI
The PXIS-2670 backplane XBP-3014L can use both PXI-compati-
ble products and standard CompactPCI products.
The signals on the P1 connector of the backplane meet the
requirements of the CompactPCI specification for both the periph-
eral 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-2670.
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 con-
troller 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 trig-
ger line between itself and slots 3-14 is intended for modules with
ST functionality that can provide individual triggers to the peripher-
als.
