A data transmission link is especially designed to meet new FCC regulations setting 5 KHz band widths for transmitting control signals to industrial systems. The new band width creates timing distortions which are overcome by inserting a new timing pulse into a data pulse stream. The center of that inserted timing pulse is taken as an axis of reference for retiming each pulse in the data pulse stream so that the fluctuations of a time frame synchronizing pulse become irrelevant. The retiming process is repeated for each data time frame.

A method of retiming a data pulse stream after a possible time distortion caused by a transmission line during a transmission of said data pulse stream, said method comprising the step of: detecting a synchronizing pulse in said data pulse stream, starting a timer responsive to a pulse transition edge following said detected synchronizing pulse, generating and inserting a new timing pulse into said data pulse stream at a location following said synchronizing pulse response to said timer, dividing said new timing pulse by two in order to identify a calculated time at the center thereof, and retiming said data pulse stream following said insertion of said new timing pulse relative to said calculated time identified at the center of said new timing pulse.
