Using + type screw driver to loosen the screw between the panel and mother board, then embed the motherboard to the side wall with
the plastic plug and screws.

1. Confirm the electric voltage (DC12V) and differentiate positive anode and cathode of power supply
2. When external Power is used, make sure sharing the power with Controller Box or using the same GND
3. When the distance between card reader and controller is more than 50m, please use Power Line with at least 1.5 square cm Dia,or using several parallel Network wires.
