# 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
