The RailCom® and update enabled decoder (only digital) is suitable for the switching of functions such as light for the DCC system. It does not feature a motor connection and is preferably built into wagons or driving trailers where it can switch for example the headlights or the interior lights. The true to the original light change will also happen on ordinary DC layouts. The decoder features 4 exits, 2 of them are pre-installed for the white and red light change at the front. 2 more exits can be activated by choosing the functions f1 or f2 of the control unit. The parameters can be largely changed for each function output. For each output, the brightness can be adjusted individually (dimmed), or you can also select a flashing mode.
