2.0 Mode of operation
1) Ignition=OFF. Nothing happens. M2-ATX-HV is waiting for ignition signals.
2) Ignition=ON. M2-ATX-HV waits for few seconds then turns on the 5VSB rail. After another
second M2-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. The Ignition state will be latched for 60 more seconds so that the motherboard will
have a change to come up in a clean manner.
3) Ignition=ON. Your computer will remain ON.
4) Ignition=OFF. M2-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) M2-ATX-HV will go to step 1, if ignition is tuned ON again.

Operating at temperatures above 85C / 185F will drastically reduce the MTBF. When operating at high temperatures or fanless
operation, must reduce PSU load by ~25%.
