Claim 15:
16. A controller for reading of RS485 and Wiegand data signals from a user connector having a first and a second output port, the controller comprising:
an RS485 transceiver with two input ports coupled to the user connector for reading data signals on said first and second output ports, and an output port for providing an RS485 data signal that is defined by the data signals read on said first and second output ports;
an RS485 interface with an RS485 data port coupled to said output port of the RS485 transceiver for receiving the RS485 data signal;
a Wiegand interface with a Wiegand data port coupled to said output port of the RS485 transceiver for receiving the RS485 data signal and a data ready port coupled to the two input ports via a first logic circuit, comprised in the controller, for determining whether the RS485 data signal is to be read as a Wiegand data signal or not on the Wiegand data port.
