FREMONT, California March 3, 2011 – Elma Bustronic Corporation, an industry leading designer and manufacturer of high performance backplanes now offers a new 3U 6-slot OpenVPX backplane with a twisted-ring routing topology.

Compliant to VITA 65 specifications for OpenVPX, the 6-slot backplane has configurable thin pipe links for distributed Gigabit Ethernet to slot 1 through slot 5 and two fat pipes for rear I/O. In slots 1-5 any or all of the P1 thin pipes (x2 channels) assigned to the control channel star can be reconfigured as rear I/O by removing zero ohm SMT shunts.  In slots 1-5 all P2 differential pairs are available on the rear side for I/O.  The OpenVPX backplane also features a Gigabit Ethernet Control Plane providing a separate star or dual star network for out-of-band communication. This can be particularly important for system management, software and firmware upgrades, and initiating new processes on specific boards.

 The lead time is 2-4 weeks ARO.
