4. Signalling Environment
4.1 V(I/O) Setting
The backplane provides a block of three high-current terminals (designated as V(I/O)) for connecting V(I/O) to either the +5V or +3.3V power supply. V(I/O) must be connected either to the
+5V or the +3.3V input power. It is the responsibility of the system integrator to ensure that the
required signalling voltage is implemented and that the backplane P1 connector coding corresponds to the implemented signalling voltage.
Warning!
Using both 3.3V and 5V boards within the same system may result in
damage to your equipment. Please note that the presence of only one
5V board determines a 5V signalling environment. The default setting
is 5V.

CPCI Backplane PD02: CP3-BP4-M
4.2 P1 Connector Coding for V(I/O)
The CompactPCI Specification foresees coding of the P1 connector to correspond to the signalling environment of the PCI bus. For this reason, only boards with universal or the corresponding 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.
Warning!
Using boards with an inadequate signalling voltage may result in damage to your equipment. Therefore, when changing the signalling environment 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 Manual, ID 24229, for details).
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.

5.2 Power Supply Connector
The input voltages to the power supply unit and the V1 ... V4 output voltages from the power
supply unit to the backplane are connected via a 32-position, DIN type M, female power supply connector.

Warning!
System integrators must ensure that only power supplies which comply
with the pinout as provided in Table 3 are used with this connector!
Pins B2, B5, B28, and B31 do not comply with the CompactPCI Power
Interface Specification.

5.3 Auxiliary Signal Connectors
The connection of the auxiliary signals is accomplished via two 5-contact, 2.54 mm pin-row,
male connectors, JP1 and JP2, which can be soldered or wrapped or be used with appropriate connectors.
