1. Confirm the electric voltage DC12V and differentiate positive anode and cathode of power supply

2. When external Power is used, suggest to use same power GND with controoller panel.

3. The wire connects reader to controller, advise use 8 cores stranded twisted pair cable(among them,two strands are spare,if no need reader show illegal cards by sound and lightm, SPK,LED wire can not be used, data wire Data 1 Data 0 are twisted pair would be better ,we suggest sectional area are 0.22 square millimeterat least.The length should not exceed 100 meters. Shielded wire connect to GND, over striking and double strand cable will improve reader working performance.
