My camera doesn't have a PC port, can I place a YN-622C transceiver on top of the camera, and connect the pc cable from the YN-622C to my strobe? I'm assuming I can, but I'd like to double check. Likewise, can I have a 580EX II set as master disabled sitting on top of my camera and then attach a PC cord from the flash to the strobe to fire the strobe?
