DMX AM-8.3 – How to Control Different Light Colors on Separate Floors?

Hey! I’m a complete beginner and honestly, I have no idea how this stuff works. I’m using a device called the DMX AM-8.3 from Sigma Net. The building has three floors, and each floor should have a different light color when turned on. There are 5 basic color options, but when I turn on, for example, red on one floor, it changes to red on all floors. I want each floor to have independent control of the light colors. Any ideas how to set this up? I’d really appreciate simple explanations. Thanks in advance!
