So, Just got my first Einstein and went the cyber commander route as I want to add more lights as time goes by. At the moment I also have and use 3 600 ex RT's and a st e3 RT. Will I be able to plug the Cyber commander into my PC port on camera, and have the Canon RT transmitter (Plan on using a 600 as a Hair light) attached as well and get both to fire? or do I need to buy one of the Paul C Buff receivers? I can't find reliable documentation of this working but would be super happy if it did~
