NOTE:
In ACC On mode, the Power 1 connector must connect to the ACC on
signal to be able to control system power.
The ACC On mode is designed for vehicle applications. When the TANK-700 is in ACC
On mode, the main power input is the Power 1 connector and the backup power is from
the Power 2 connector.

When both power connectors are connected to a power source with over 9 V, the two
power LEDs on the front panel remain off until the ACC ON signal jumps from low to
high. The user can choose AT power mode or ATX power mode to control the system.
The following flow diagrams show the boot-up process and the LED status in AT and ATX
power modes.
