1.3.1 PXI Bus Interface
The system controller PXD-3710/3710F follows the PICMG 2.8
Instrumentation Extensions to CompactPCI specifications. PXI specifications
dedicate the leftmost slot of the PXI chassis to the system controller. PXI is
electrically compatible with the PCI bus standard, and provides enhanced
instrumentation signals for synchronization or communication between
peripherals. Based on the mechanical design of CompactPCI systems, PXI
systems can work in harsh, shocking, and high temperature environments.
The PXD-3710/3710F utilizes a 32-bit/33MHz PCI bus. The 64-bit PCI
signals on the PXI J2 connector are not used and therefore reserved for rear
