The PCB Cyber-Commander is a seriously useful tool, especially if you've got 5-6 Einsteins set up for a shoot, and some of them out of reach, but perfectly positioned. But the GUI of the CC is very rudimentary, definitely not a design that Jonny Ive would approve of! Bluntly, it's a shocker. But once learned, it's wacky logic is pretty obvious.
You'd be best off getting some help at the PCB Technical Forums http://www.paulcbuff-techforum.com/
FWIW I used the CC on the hotshoe a total of once. It was fiddly and annoying. Far better to keep it in your pocket or on a lanyard, and adjust your settings as needed. Trigger the flashes with Cyber Sync trigger http://paulcbuff.com/cst.php on camera and the Cyber Sync receiver http://paulcbuff.com/csxcv.php plugged into the Einstein.
Enjoy the Einsteins. They're the best.
