Backplane Overview
3.1 Interoperability with CompactPCI
The PXIS-2650 series backplane cBX-3008L can use both 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-2650 series.
3.2 System Controller Slot
The System Controller slot is located at 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 spotted at Slot 2. This slot has a dedicated
trigger line between itself and Slot 3 to 8 is intended for modules with ST
functionality that can provide individual triggers to the peripherals.
