System Components
Ribbon Cable Connections
The ribbon cable has symmetrical
connectors, so that either connector
can be used for either connection.
In order to eliminate the risk of
installing the connector in the wrong
orientation, each connector of the
ribbon cable is equipped with
keying/polarized feature, which
means that the connector can only
be installed in one orientation.
Figures 6.23 and 6.24 show the
ribbon cable connection to the I/O
board.

Note: Do not force inserting the
ribbon cable connector on the
opposite orientation as it could
damage the plastic and cause
malfunction of the I/O Board.
