The Canon flash units do NOT have a simple optical slave mode, you must use E-TTL to trigger them.  This is Canon's attempt to force you to use only their hot-shoe flash units.

The solution is to use a hot-shoe optical slave like those suggested by Klaus dk, fotowbert, and Boomanbb.  There are no pre-trigger flashes to be ignored with your PCB CyberCommander and Einsteins so all you need is a simple hot-shoe optical trigger.

If you want to get fancy you might try using Yongnuo YN-622C triggers.  Mount one on the camera then mount the CyberCommander on top it.  Mount the 430EX II and 600EX RT on additional YN-622Cs.  If this works you have remote control of the Canon flash units and they should trigger in sync with the Einsteins.
