 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)
