A communication system controller having an input for receiving output signals of a sending device. The communication system controller further has a clock signal. The communication system controller further has an output for transmitting input signals to a target device. The communication system controller further has a signal processing element capable of determining if the received output signals of the sending device are synchronous with the clock signal. The signal processing element is further capable of determining if the received output signals of the sending device are asynchronous with the clock signal. The communication system controller is capable of transmitting the received output signals of the sending device as input signals to the target device if the received output signals of the sending device are determined to be synchronous with the clock signal.
