Well we just got the Pocket Wizard AC9 for Alien Bees B1600 and could not get it to work. No one on the internet had any helpful advice to get the AC9 for Nikon to work, which is why we created this support page. We called Pocket Wizard and they could not get it to work either. They said we were the first to call for the Nikon version. But we found the solution on our own. As you know we proudly use Nikon therefore we are one of the first to use the AC9 for Nikon. What you have to do to get it to work:
Go to Pocket Wizard utility (open)> plug in your TT5 with the AC9 attached> Click on the little blue gear on the bottom left corner of the Pocket Wizard utility (the configure updates button)> Click on the firmware updates tab (note: simply updating firmware to the latest update wont do it, you have to manually get the beta test firmware)> Click on "yes i would like to have access to the beta test firmware (version 2 build 146 or Latest Beta)> Hit OK and download the firmware (version 2- build 146 or Latest Beta)> Then repeat the process for the rest of your TT1's and TT5's and your good to go. (Note: make sure you have the dummy mini sync cord in to shut down the optical slave)
