I have (4) AS-201 strobes and I am having what I hope is a simple problem.
Here is my setup for my test:
(1) AS-201 connected by PC Sync
(1) AS-201 triggered by optical sensor on unit
I cannot get the Britek's to sync fire with my camera if I have my 430EX firing from my cameras hotshoe. Once I take off the speedlight and trigger them with the PC Sync cord to one of them, they both sync up fine with my camera.
Also will not work with the on-board flash.
I also tried this on my 40D and have the same issue so I'm betting it's not the camera?
Tried shutter speeds from 1/60 to 1/250 with the 430EX firing 1st and 2nd curtain sync.
Any suggestions or tips would be GREATLY appreciated.
