General Description
This standard backplane is member of the ERNI backplane familiy for
use in Compact PCI computer systems. Its high-performance features
make it ideally suited for telecom, datacom, and industrial applications
like CNCs, robotic controls, and video image processing.
The inherent limitations of Compact PCI are broken by the use of a
Optional this backplane may be used to implement a two-bus multiprocessor system when equipped with a non-transparent bridge
ERNI develops and manufactures backplanes according to ISO 9001
at several productions sites around the world.
Custom and semi-custom designs based on our standard backplanes
are possible in various configurations.
