4.2 P1 Connector Coding for V(I/O)
The CompactPCI Specification foresees coding of the P1 connector to correspond to the sig-
nalling environment of the PCI bus. For this reason, only boards with universal or the corre-
sponding coding can be physically inserted into the backplane. PEP’s factory default setting
for V(I/O) is +5V and male, 1567 code, brilliant blue coding keys are used.
5. Interfaces
5.1 Line Connector
Instead of a 3-pole Mate-N-Lok connector the power supply to the backplane is connected by
means of 3 separate pins on the reverse side of the backplane, to which power supply cables
should be soldered.

Warning!
Using boards with an inadequate signalling voltage may result in dam-
age to your equipment. Therefore, when changing the signalling envi-
ronment from 5V to 3.3V or vice versa, it is mandatory that proper
coding keys are used (refer to chapter 3 of the CPCI Backplane Man-
ual, ID 24229, for details).
