The system controller and calibration management system

By the end of 2005 the PC industry, commercial bus technology evolution from PCI to PCI Express, diesel pump manufacturers ， increase the available bus bandwidth. At the same time, PXI PXI Express technology is introduced, significantly improved bus bandwidth. PXI combines PCI Express integrated into the PXI standard, to meet the more demanding applications.

PCI Express technology can be integrated into the backplane, with existing systems while maintaining backward compatibility. In addition to x1, x4, gas station management software  and x8 PCI Express links, the system controller slot supports up to x16 PCI Express link that can provide up to 6GB / s of bandwidth PXI Express backplane.

The use of PCI Express technology, PXI Express to increase PXI bandwidth available in more than 45 times, that is up from 132MB / s to 6GB / s; at the same time, automatic vehicle identification system you can also maintain PXI modules and software, and hardware compatibility. Because of this enhanced performance, PXI can be used in many new applications, which in many areas achieve only by expensive and proprietary hardware in the past.
