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.
