Summary:A controller, a method and a medium for reading RS485 data signals and Wiegand data signals are provided. The controller includes an RS485 transceiver having: two input ports, each of which is connected to a respective one of the two output ports of the user connector to read one data signal from each of the output ports of the user connector; and the output ports are used for providing RS485 data signals defined by the data signals read on the two output ports. The controller comprises an RS485 interface with an RS485 data port, and the RS485 data port is connected to the output port of the RS485 transceiver so as to receive the RS485 data signal. The controller comprises a Wiegand interface with a Wiegand data port and a data ready port, the Wiegand data port is connected to the output port of the RS485 transceiver to receive the RS485 data signal, and the data ready port is connected to the two input ports via a first logic circuit to receive the RS485 data signal from the two input ports.
