I just got a Norman 400B which I am super psyched to get into. I used one at work for years and finally got one of my own!! I also bought a Pocket Wizard PlusX to fire it with. Now I'm trying to set the channel and have the Norman pop a flash to say 'Yup, we're synched!" and I'm getting nothing. Reading and re-reading the instructions isn't giving me much more "enlightenment". Does anyone have any on the ground experience with either of these units or even more hopefully, as a pair? I'm shooting with a Pentax K-5II if that makes any difference.
