Claim 14:
15. A non-transitory computer-readable storage medium having stored thereon a computer program comprising computer code which, when run on processing circuitry of a controller comprising an RS485 transceiver, an RS485 interface, and a Wiegand interface, causes the controller to:
read, at two input ports of the RS485 transceiver, one data signal on each of two output ports from a user connector, where each of the two input ports is connected to a respective one of the two output ports of the user connector;
provide, at an output port of the RS485 transceiver, the RS485 data signal that is defined by the data signals read on the two output ports;
receive the RS485 data signal at an RS485 data port of the RS485 interface, the RS485 data port being connected to the output port of the RS485 transceiver;
receive the RS485 data signal at a Wiegand data port of the Wiegand interface, the Wiegand data port being connected to the output port of the RS485 transceiver; and
determine, at data ready port of the Wiegand interface, the data ready port being connected to the two input ports via a first logic circuit, comprised in the controller, whether the RS485 data signal is to be read as a Wiegand data signal or not on the Wiegand data port.
