WHOLE SYSTEM
You only need 1 STATION-X.
You can connect any number of Z-RAY's to your STATION-X - there is no limit to the number of Z-RAY's connected to 1 STATION-X.
STATION-X must be connected to USB power (this can come from a computer - STATION-X needs very little power).
Z-RAY doesn't matter - it can run from it's own internal rechargeable battery - or it can run whilst connected to USB power (and charge the battery at the same time).
For really simple applications you can use the STATION-X internal modes (EFFECTS or HOUSE), or set each Z-RAY to the colour you want.
But - for most users - you will want to use either a traditional lighting desk with physical sliders, or an app that is the software equivalent of a lighting desk running on your computer.
Think Radio cannot test all DMX lighting software and hardware - but everything we have tried works!
