Backplane Overview
The cBX-3008L backplane can accept both PXI compatible prod-
ucts and standard CompactPCI products. The signals on the P1
connector of the backplane meet CompactPCI specifications for
both peripheral and system modules.
PXI-specific signals are located on P2. Only reserved signals or
signals not used for the CompactPCI 64-bit specification are found
on PXI specific signals; therefore, all modules that meet Compact-
PCI 64-bit specification requirements are capable of operating in
the PXIS-2680P.
3.1 Specifications
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 (four total), 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 towards the left to prevent the
controller from using up peripheral slots.
Star Trigger Slot
The star trigger (ST) slot is located at slot 2. This slot has dedi-
cated trigger lines between itself and slot 3 to 8, which are
intended for modules with ST functionality to provide individual
triggers to the peripherals.
Peripheral Slots
There are 7 peripheral slots including the star trigger controller
slot.
