3.9.1 ACC ON Mode
1. The TANK-870AI series supports single power input and also can be simultaneously
connected to two power sources. When both power connectors are connected to
power sources with 9 V~36 V power input, the one with higher voltage will supply
power to the system.
2. If ACC signal is low, the system will not boot up. If ACC ON signal is high (9 V~36 V),
the system will boot up and work normally.
