PMC Interface Connector
The mapping used by the CPCI-6020 of the PMC I/O connectors onto the CompactPCI user I/O
connectors is reversed by the CPCI-6020-MCPTM-01. This allows the designer of a PMC to
create a PIM without knowledge of how the CPCI-6020 maps signals through the backplane.
There is nothing to tie the PIM to the CPCI-6020 platform and in this sense the module is
universal.

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-6020) and so the host I/O module is not a universal
module. However, if the host I/O connector pinout is reused on future modular transition boards,
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.

Speaker Port
The 2-pin header provides connection to an external speaker from the CPCI-6020 speaker
counter output.
4.26
Floppy Disk Port
The CPCI-6020 uses the PC97307 ISASIO from National Semiconductor to provide a floppy
disk controller. The interface is routed to the CompactPCI J5 connector. The CPCI-6020-
MCPTM-01 brings the signals to a planar 34-pin header on board. Refer to the PC97307 data
sheet for further details. This feature is supported only in the 5E variant.
4.27
Mouse and Keyboard Port
The CPCI-6020 uses the PC97307 ISASIO from National Semiconductor to provide a PS/2
mouse/keyboard interface which is routed to the CompactPCI J5 connector. The CPCI-6020-
MCPTM-01 brings the signals to a PS/2 mouse/keyboard port on the real panel. Refer to the
PC97307 data sheet for further details. This feature is supported only in the 5E variant.
