Mode of operation
1) Ignition=OFF. Nothing happens. M3-ATX-HV is waiting for ignition
signals.
2) Ignition=ON. M3-ATX-HV waits for 2-3 seconds then turns on the
5Vsb rail. After another second M3-ATX-HV sends an "ON" signal to
the motherboard via the 2 wires connected to the motherboard's
ON/OFF pins. The motherboard will turn ON and your system should
start booting.
3) Ignition=ON. Your computer will remain ON.
4) Ignition=OFF. M3-ATX-HV waits for "OFFDELAY" in seconds (see
jumper chart) and then it turns the motherboard OFF by sending a
signal to the motherboard's ON/OFF switch. Your computer should
turn off gracefully (shutdown procedure). After shutdown, 5VSB will
still be provided for another "HARDOFF" seconds. In the event where
the shutdown process is longer than "HARDOFF" (Operating System
gets frozen, etc), power will be shut down hard, turning off all power
rails. During the HARDOFF procedure, the battery levels will be
constantly monitored to prevent deep discharge situations.
5) M3-ATX-HV will go to step 1, if ignition is tuned ON again.
NOTE.
When all config. jumpers are removed, M3-ATX-HV acts as a regular power
supply, no ignition timing, no HARDOFF. M3-ATX-HV will send a gratuitous
"ON" pulse to the M/B when power is applied for the first time. Do not connect
the on/off switch if you don't want your PC to be started automatically.
