I Just got my new Canon 600ex-rt. I have a Canon 7d, a flash 430ex II, and a pair of yongnuo yn-662c wireless flash trigger transceiver.
Basically what I want to do is put one of my transeiver on my camera, to fire my 630ex and I want my 430ex II to fire as a slave.
I'm able to do it, when my flash is on my camera, but I can't do it when my 630ex-rt is mount to my yn-622c.
Is there a non-compatibility with those two? What should I do ?
Sorry for my bad english, I speak french.
Let me see if I understood correctly, are you putting the 430 on the second YN622c and still it is not working?
