Power Terminals Assignment:(Figure 3)
ATC-804 can get power from USB port. You should need External Power Supply if the USB port can’t offer enough
power. The power supply voltage should be from +12V-24V
VDC@500mA. It can connect to V1-,V1+ terminals.
(Terminal V2-,V2+ is only for power input backup)
