Functional Description
General Purpose Inputs/Outputs
The CP3002-RC/CP3002-RA provides five general purpose inputs (GPI) and three general
purpose outputs (GPO) on the rear I/O CompactPCI connector J2.

PIN on J2 SIGNAL
D15 GPI0
A3 GPI1
D19 GPI2
D3 GPI3
A21 GPI4
C18 GPO0
A20 GPO1
E3 GPO2
Note ...
The GPI signals tolerate only 3.3 V signaling and the inputs have internal pull-
up resistors.
Power Signals
The CP3002-RC/CP3002-RA provides three power signals on the rear I/O CompactPCI con-
nector J2.

PIN on J2 SIGNAL
B4 5V
E19 3.3V
A4 VI/O
C19 Back-up 3.3V
C12 RSVD
Warning!
Pin C12 MUST NOT be connected to any signal, either within the backplane
itself or within a rear I/O module.
Failure to comply with the above will result in damage to your board.
For further information regarding the rear I/O signals, please contact Kontron.

CompactPCI Grounding Configuration

On the CP3002-RA, the chassis ground and the digital ground are not isolated due to the direct
mounting of the front panel to the heat sink. Thus, the CP3002-RA can be operated only in a
system with common grounding.
