Connect a PoE adapter or a 12V DC / 3A power adapter (not included). When
using PoE:

Note:
To calculate the total power consumption, add the power consumption of the
controller, output devices and readers connected. For example, if you connect 4 GV-EL202B
and 8 GV-DFR1352 to the GV-AS2120, the total power consumption will be 25.16 W.
⚫ Each GV-EL202B uses 3.6W * 4 = 14.4W
⚫ Each GV-DFR1352 uses 0.72 W * 8 = 5.76 W
⚫ GV-AS2120 uses 5 W
Total power consumption: 14.4 + 5.76 + 5 = 25.16 W
