procedure until successfully turn on motherboard.
C.
Power smart function sends "ON" pulse to motherboard when ignition is on for
more than 2 seconds.
D.
Power smart function will ignore the status change of ignition after ON pulse is
send to motherboard for 3 minutes. After this period, the Power smart function will
start to check its status. This can avoid an improper "OFF" process before the OS is
complete booted.
E.
Power off is controlled by remote switch or ignition. Remote switch has higher
priority than ignition. (Remote switch is optional).
F.
Power smart function sends "off" pulse to motherboard 5 seconds after ignition is
turned off or remote switch is pressed. (Soft delay)
G. Power smart function will ignore the status change of ignition and remote switch
during the "OFF" pulse is sent out and the /PSON return to high. This will avoid an
improper ON process before the motherboard is completely shot off.
H.
The digital output (optional) will go from high to low at the moment that "OFF"
pulse is sent to motherboard. The low state will be kept until /PSON back to high. If
the /PSON does not back to high within 3 minutes, the Power smart function will
enter a retry cycle (described in next section).
I. Power off retry: If the motherboard cannot be shouted down normally (/PSON does
not go to high) within 3 minutes after "OFF" pulse is sent, the Power smart function
will send off pulse to motherboard again. If the motherboard still cannot be shouted
down normally, the power output will be turned off directly. (Figure 3)
J. Hard off delay: 1 minutes, During this period system can be turned on again if the off
procedure already finished and power button is pushed again(or ignition on again)
