Trigger a 580EX II with a Cybersync Commander

[pierceography]

Hi Everyone,
So I received my first Einstein and Cybersync Commander today, and I'm trying to trigger a 580ex ii as a slave. However, I'm reading that the 580ex ii can't be triggered as an optical slave by a non-Canon flash. So my question(s) are: 1) Is this true? And 2) If so, how can I trigger the 580ex ii as a slave? Can I use the cord from the Einstein to the 580ex ii or do I pretty much have to pony up for another PCB wireless trigger?

Thanks in advance for the help!

Another PCB trigger may be easiest. Or, you can get an Sonia attachment to make your 580 a generic optical slave ($16, you need the ones with a green base).
