Pocketwizards have upgraded their tt1/tt5 firmware to add new features. But, as you’ll know if you follow me on Twitter or Google+, I’ve been struggling to get this sceanrio working:

tt1 on camera
580ex II on tt5
second 580ex II trigger by IR from first 580ex II

But, the IR trigger only works if you have the 580 on the tt1 it would seem. Unfortuanely, for me at least, this doesn’t seem to have been addressed in this upgrade.
