A communication system, which is particularly useful for communications onboard a vehicle, allows a single, low cost controller (30) to communicate with more than one device (32, 34) using a single, synchronous communication interface (50). An adjuster module (72) selectively adjusts a speed of a synchronous clock (54) associated with the communication interface (50). The adjuster module (72) lowers the speed of the clock to allow the controller to communicate through another communication port (68, 74) that is separate form the synchronous communication interface (50). The adjuster module (72) and the additional communication port (68, 74) facilitate communication with more than one device even though the controller has only a single transmit port (56) and a single receive port (58) that are part of the synchronous communication interface (50).
