The Crane is controlled like a conventional DCC sound loco using a DCC locomotive address and controllable functions. Function 2 is important as it allows you to rotate the crane. Your system needs to be able to lock F2 on. The majority of DCC systems do this as the factory setting. I have used Lenz, Roco, Fleischmann, ESU, Piko and Uhlenbrock and all these are fine.
Optional control with a PS4 wireless handset
Connecting the PlayStation4 Controller to a PC and Roco Z21 to control the crane. (EDK750 PC programme from the z21.eu website - Click Here)
