30 CMX34GS cpuModule BDM-610000082 Rev A
Speaker
A speaker output is available on pins 1 and 2 of the Utility Port 2.0 connector. These outputs are controlled by a
transistor to supply 0.1 W of power to an external speaker. The external speaker should have 8 Ohm impedance
and be connected between pins 1 and 2.
System Reset
Pin 3 of the Utility Port 2.0 connector allows connection of an external push-button to manually reset the system.
The push-button should be normally open, and connect to ground when pushed. The type of reset generated by
this button can be set in the BIOS configuration utility.
Soft Power Button
Pin 5 of the Utility Port 2.0 connector allows connection of an external push-button to send a soft power signal
to the system. The push-button should be normally open, and connect to ground when pushed. For more
information on the modes of the Soft Power Button, refer to the Power Management section in Chapter 4, Using
the cpuModule.
