Pin#1 and pin#2 are used to turn on or turn off the system remotely by connecting to an
external switch. Users should connect a non-latched switch to Ctrl+/Ctrl- as it acts exactly
the same as the power button on the front panel. For detail information of using remote
on/off control function, please refer to section 3.7.2.
Pin#3 to pin#10 are used to output the system status including power, HDD, ignition signal
and watchdog timer status. The status LED output has a built-in series-resistor and
provides 3.3V, 10mA current, which means you can use these pins to directly drive an
external LED indicator.
