# Script to operate a Roco crane from screen # # The crane DCC addresses are set by the user in the main window # This is for the older Roco crane (part number 46800 (DCC))or newer ones where the user has not set CV53 to 2 # Functions are as follows # Rotating the crane: # F0 # LED (GREEN) flashes in single-cycle interval # Raising and lowering the Boom: # F1 # LED (GREEN) flashes in two-cycle interval # Raising and lowering the crane hook # F0 F1 # LED (GREEN) flashes in three-cycle interval # Additional function Magnet, Bucket or Spotlight # Throttle Rev and 1 speed step = OFF, Fwd and 1 speed step = ON # LED may light up RED # # Author: Nelson Allison, copyright 2009 #
