CompactPCI Connector Keying
CompactPCI connectors support guide lugs to ensure a
correct polarized mating. A proper mating is further
assured by the use of color coded keys for 3.3 V and 5 V
operation. The CP342 versions support 3.3V VIO and are
5V tolerant (universal). Therefore, there is no keying
necessary.
