The RailSync lines communicate a copy of the track signals to the Boosters for amplification and transmission to the rails. RailSync lines can power a limited number of LocoNet connected devices on small layouts. As the number of power consuming LocoNet devices attached to LocoNet increases, the need to separately power those devices increases.
RailSync is a low power signal that mirrors the Digital Command Control packets on the rails. It is generated by the Command Station and sent out via LocoNet (pins 1 & 6) to devices such as Boosters, Occupancy Detectors and any other device which requires RailSync to operate. Boosters receive the RailSync data, amplify or boost the signal and output it to the track. RailSync can also be used as a source of power for low current devices such as throttles.
RailSync uses pins 1 and 6 of the LocoNet cable.
