System components
Ribbon cable connections:
The ribbon cable has symmetrical
connectors, so that either connector
can be used for either connection.
To eliminate the risk of installing the
connector in the wrong orientation,
each connector of the ribbon cable
includes a keying/polarized feature,
which means that the connector can
only be installed the correct orientation.
Figures 6.31 and 6.32
show the
ribbon cable connection to the
controller board.

Note: Do not force the ribbon cable
connector in the wrong orientation
as it could damage the plastic and
cause the I/O Board to malfunction.
If the connector does not insert
easily, check to be sure you are not
attempting to connect it in the
wrong orientation.
