I have a Canon T2i with a 430ex ii and recently bought a radio transmitter kit (YN-622C and YN-622C-TX). The setup works, i.e.the TX on the camera, the 430ex on the 622C transceiver, all on channel 1 and group A and the flash set to slave. The flash fires as I shoot.
But I can't seem to be able to control the flash power from the TX unit. Thus every shot after lowering or elevating the values the flash fires with the exact same setting. I have to set the flash on manual and then adjust the setting at the flash, which beats the purpose of my TX unit. Anybody have a similar setup or experienced this problem?
