Loop-Back Test Switches (SW6 and SW14)

The loop-back test switch SW6 is located at the top left side of the board. The second loop-back test switch, SW14, is located at the top right side of the board. These switches are used only for testing; all switch positions should be OFF.

Push Button Enable Switch (SW7)

The push button enable switch (SW7) disconnects the push buttons from the corresponding processor pins. This allows the signals to be used for another purpose. Table 2-6shows the SW7 connections. By default, all position of the SW7 switch are ON, allowing the push buttons to function as designed.
