12.6 Speaker and Miscellaneous Connector
J3 is used for optional connection of an auxiliary speaker or control switches.
The panel board contains a miniature speaker which is enabled by default. To enable this speaker, install a jumper across pins 11 and 13 of J3 (default setting). If a different speaker is desired, or if no speaker is desired, remove the jumper.
To connect an auxiliary speaker, connect the speaker across pins
External momentary switches may be connected to J3 to control power or reset. For power, connect the switch between pins 1 and 2 of J3. For reset, connect the switch between pins 3 and 4. Each switch operates by connecting the selected control signal to ground.
To lock out the keyboard and mouse ports on the panel board, install a jumper across pins
An auxiliary switched +5V pin is provided on J3 for customer application. In addition the unswitched power may be used on this header to power a panel light or other customer circuit, with the current limited to 1A.
