I am new in this field so please be patient with me

I just bought 1 RGB laser on ebay, only thing i got with it is two pages of operating instructions.
It supports DXM 512 and there are few tables with dim switch positions for Sound,Auto,Animations,DMX512 address.
I was searching for serial number or a name but there is just two things written, TVS(r) and Doplhin.
Please is there anyone who can help me with laser and not to connect it properly to FreeStyler?
Thank in advance, I really appreciate any hint!
