Hi Jeco,
The WDP user Werner Kroha gave me the following answer:
"I'm using the RocoMouse 2 with the Lenz LI101F. WDP you have to set to Lenz V3."
The Retrosignalisation is not implemented in the RocoMouse, he is using the HSI from Littfinski Datentechnik instead.
So far he had no problems
Best Regards Bernd
