General information
DCC Categories Beginner, Command Station

Command stations retransmit packets to mobile digital decoders as often as possible, so if one packet is lost, another one with the same information will arrive soon after. If power to the locomotive is interrupted for long enough, the digital decoder goes into reset mode - and stops the locomotive. When power is restored, it will not move until it gets a new packet.
