Abstract:
1. A method for communicating between a bus controller and at least one data channel via a common digital bus, the method comprising: communicating between a bus controller and at least one data channel using a first bit rate; transmitting a first message from the bus controller to the at least one data channel at a predetermined second bit rate, wherein the predetermined second bit rate is selected from a predetermined number of different bit rates that may be used to communicate on the common digital bus; receiving the first message at the at least one data channel; analyzing the first message at each of the predetermined number of different bit rates upon receipt of the first message by the at least one data channel; determining from the predetermined number of different bit rates that the first message is being transmitted at the second predetermined bit rate at which the first message was transmitted, where the determination is made independent of a synchronous clock signal from the bus controller; and transmitting a second message from the at least one data channel to the bus controller in response to the first message at the second predetermined bit rate.
