VITA 46, 48, and 65: The Next Generation VME system replacement. VITA 46 is the VPX base electrical and mechanical specification. VITA 48 is the VPX REDI cooling spec. VITA 65 is Open VPX. Open VPX was the industry's attempt to bring order to chaos. Open VPX methodically defines a system of profiles that would fully explain the interactions between the backplane and plug-in modules. The profiles are the physical mapping of resources in the system. This information can then be used to determine compatibility.
