The module works great with the 422D and ringlights. there is supposed to be a battery attachment which didnot come with the module. Even though this allows the flash units to work in ttl mode with the Nikon af cameras it DOES NOT work with the digital cameras and could possibly damage the digital bodies.
Since it doesn't work with the digital Nikon models, I'd say it is outdated. Sunpak should do something about that!
