PMC I/O Module Form Factor

The PMC I/O module form factor is identical to the single-wide PMC form factor with the
following differences:

Shorter by 80mm

Deletes the +5 V and +3.3 V keys

Pn1 and Pn3 are deleted

The 80mm is “cut out of the middle” of the PMC I/O module. This means that features in the
front half of the module keep their positioning relative to the front edge of the board while
features in the back half of the board keep their positioning relative to the back edge of the
board.

5.7.9

PMC I/O Connector

The mapping used by the CPCI-6200 SBC of the PMC I/O connectors onto the CompactPCI user
I/O connectors is reversed by the CPCI-6115-MCPTM. This allows the designer of a PMC to
create a PMC I/O module without knowledge of how the CPCI-6200 SBC maps signals through
the backplane. There is nothing to tie the PMC I/O module to the CPCI-6200 SBC platform and
in this sense the module is “universal”.

5.7.10 Host I/O Connector

The second connector on the PMC I/O module is used to provide power and ground to the
module. In addition, the remaining pins may be used for host I/O signals. Any host I/O
functionality for which there is no space available, or which the cost of does not justify its
presence on the standard board, may be implemented in a “host I/O module”. This
functionality is special to the host (in this case the CPCI-6200 SBC) and so the host I/O module
is not a “universal” module. However, if the host I/O connector pinout is reused on future
transition modules, the host I/O module may be reused.

If possible, optional host I/O routed to the host I/O connector will be terminated in such a
fashion that the host does not incorrectly determine that a device is connected to that I/O
when no module is present. This termination must not interfere with normal operation of the
I/O when a module is present.
