michael kilner Offline • • • • • Upload & Sell: Off p.1 #1 · puzzling issue re triggers I have just acquired a 2nd hand set of calumet genesis 200 strobes which came with 2 triggers and a hotshoe transmitter.When I connect both triggers and fire the flash only one head fires (both optical slaves are turned off).The flash that fires I shall call no 1 as it is the head which actually has sync written on it next to the port.If I turn off head one and fire the camera, head 2 will then fire but if I again power up both heads only head one fires.I get both heads to fire by turning on the optical sensor in head 2 and all is fine.I hope it is me being dim but I was under the impression that if both heads where connected to triggers via their sync ports then they would both fire whether the optical slaves were on or not.Forgot to mention that the triggers are the inline mains type and swapping them around gives exactly the same result Dec 01, 2012 at 05:33 PM

That is odd. The only thing I can think of is that the optical sensor isn't being cut out when the radio trigger is plugged in, and a doubled sync signal is locking it up. To rule that out, try putting a piece of black tape over the optical sensor on the problem head and see if it then works with both strobes firing. Dec 01, 2012 at 06:34 PM

The optical sensor should disconnect when the receiver is plugged in; something must be stuck inside...or loose...or something. (I don't know much about Calumet products.) As long as you don't mind the black tape being there, it should work that way indefinitely. Dec 01, 2012 at 07:22 PM
