8 : D0 Wiegand Data Output Port
This output port provides the D0 Wiegand data. Connect it to the D0 input port of the controller.
9 : D1 Wiegand Data Output Port
This output port provides the D1 Wiegand data. Connect it to the D1 input port of the controller.
10 : RS-232 (TX) Output Port
This is a standard RS-232 transmission output port. Connect it to the COM port of the PC.
See following diagram for the details.
