THEMA:

I am trying to configure a Vortex 250 Pro quad, using Jeti Tx and a Rex3 Rx. I have set Rx to output PPM (Positive Output) and used the Vortex Configurator to look for CPPM, but when starting the OSD Wizard, I now get channel bars which are 'blank' with '0' values, when the system requests sticks centred, but the Wizard does not go any further.
What am I doing wrong, please? I am pulling my hair out!
