PXI-1025 Backplane Overview

Interoperability with CompactPCI

The PXI-1025 MegaPAC backplane is interoperable with PXI-compatible 
products and standard CompactPCI products. This is an important feature, 
as many PXI-compatible systems may not 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 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 and are found on only 
the signals that are 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-1025 MegaPAC.

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.

Star Trigger Slot

The Star Trigger (ST) slot is Slot 2. This slot has a dedicated trigger line 
between each peripheral slot (see Figure 1-3). This slot is intended for 
modules with ST functionality that can provide individual triggers to all 
other peripherals. Additionally, you can use the ST slot as a high-precision 
10 MHz clock source. However, if you do not require advanced trigger 
functionality, you can install any standard peripheral module into this slot.

Peripheral Slots

There are seven peripheral slots including the ST slot.

Local Bus

The PXI backplane’s local bus is a daisy-chained bus that connects each 
peripheral slot with its adjacent peripheral slots to the left and right, as 
shown in Figure 1-3.
