Originally posted by derekkite A quick glance through the manual a week ago, there was a section on how to power up the whole thing so that they all talk. I wonder if is a reference to the power up procedure? Or a vague mistranslation.
There
is a weird power-up procedure, but it makes sense when you consider that the "normal" P-TTL communication is bi-directional, and the triggers exist inside this loop. Briefly; power up the receiver, then the flash, then the transmitter, then the camera. In this order, the receiver has a signal to send that tells the camera what "flash" is mounted on its hotshoe, and the camera can send a signal to the flash.
If this order isn't followed, things might still work, but there is potential for the camera to not "know" a P-TTL flash is attached, or for the triggers to not communicate properly, etc. After I learned it, it became second nature.
