Hi, I had a profilux 3ex and now upgraded to profilux 4 also have 3 Mitras LX6300 lights. I used expansion card PLM-PWC (Radio module) to communicate P3ex with the lights as slaves. Do I still need this expansion card to do the same with the P4 or will they communicate any way as P4 has its own WiFi? If this is the case how do I set it up?
