Abstract:
A method for transmitting data by a transmitting device connected to an IEEE-1394-1995 serial data bus, comprising the steps of:(a) transmitting, by the transmitting device, a data packet onto said bus at a known speed, said data packet containing identification information of a target receiving end device connected to the bus; (b) detecting, by said transmitting device, whether an acknowledgement signal was sent by the receiving end device confirming receipt of the transmitted data packet; (c) if an acknowledgement signal is detected, setting, without the use of a bus manager, a transmission speed for a subsequent data transmission by the transmitting device to the target receiving end device at the transmission speed of said transmitting step; and (d) if no acknowledgement signal is detected, repeating step (a) at a reduced transmission speed and then repeating steps (b) and (c).
